When I try to run ionic commands like ionic serve on the VS Code terminal, it gives the following error.
How can I fix this?
ionic : File C:\Users\Lakshan\AppData\Roaming\npm\ionic.ps1 cannot be loaded because running scripts is disabled on this system. For more information, see

I found a way to fix this error.
It is as follows:
First, Open PowerShell with Run as Administrator.
Then, run this command in PowerShell
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned
After that type Y and press Enter.
This is because of Execution Policy. This defines how powershell scripts will run.
In Default windows desktops, it is Restricted, not allowing any scripts (signed or unsigned) only interactive sessions.
So best is you set using RemoteSigned (Default on Windows Server) letting only signed scripts from remote and unsigned in local to run, but Unrestriced is insecure lettting all scripts to run.
To set run Set-ExecutionPolicy -ExecutionPolicy RemoteSigned as administrator.
This code will fix it:
Set-ExecutionPolicy RemoteSigned –Scope Process
To Bypass this you need to change the Execution policy.
Type this into your terminal.
Set-ExecutionPolicy -Scope CurrentUser
then it will prompt you to supply a value at which point you can set Bypass / RemoteSigned or Restricted.
cmdlet Set-ExecutionPolicy at command pipeline position 1
Supply values for the following parameters:
ExecutionPolicy: "RemoteSigned" or "Bypass" or "Restricted".

I am trying to set the execution policy to Unrestricted, but I'm getting the following error:

Execution Policy Change
The execution policy helps protect you from scripts that you do not trust. Changing the execution policy might expose
you to the security risks described in the about_Execution_Policies help topic at
http://go.microsoft.com/fwlink/?LinkID=135170. Do you want to change the execution policy?
[Y] Yes [N] No [S] Suspend [?] Help (default is "Y"): Y
Set-ExecutionPolicy : Access to the registry key
'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell' is denied. To change the execution
policy for the default (LocalMachine) scope, start Windows PowerShell with the "Run as administrator" option. To

Set-ExecutionPolicy defaults to setting the script execution policy for the whole system (implied -Scope LocalMachine).
-Scope LocalMachine can only be used from an elevated session (run as admin);[1] if your session isn't elevated, you'll get the error you saw - and the error text actually both explains the problem and provides instructions for how to resolve it.
To summarize:
Either: Re-run your command from an elevated session, assuming you have administrative credentials.
You can start one with Start-Process powershell -Verb RunAs (use pwsh in PowerShell (Core) 7+).
Or: Change the persistent execution policy only for the current user (-Scope CurrentUser)
Set-ExecutionPolicy -Scope CurrentUser RemoteSigned -Force
Note:
I've chosen RemoteSigned as the policy in the sample call, as it provides a balance between security and convenience: it places no restriction on local scripts, but prevents execution of scripts downloaded from the web that aren't cryptographically signed.
-Force bypasses the interactive prompt.
While a current-user execution policy takes precedence over a local-machine one, both can be preempted by GPO-based policies - see this answer for more information.
There's also a way to set the execution policy for a single session only, via -Scope Process, though that is typically used via the PowerShell CLI (powershell.exe for Windows PowerShell, pwsh for PowerShell (Core) 7+), in the form of -ExecutionPolicy Bypass.
[1] While the same applies to PowerShell (Core) 7+ in principle, elevation is not required if you happen to have installed it in a current-user location. Also note that execution policies fundamentally do not apply when you use PowerShell (Core) 7+ on Unix-like platforms.
I am trying to run virtualenv script to activate it on powershell using:
.\env\Scripts\activate.ps1
but I get this error:

I read this article and I tried to solve this by running powershell as administrator and type this command:
Set-ExecutionPolicy RemoteSigned
but unfortunately nothing change
According to this earlier asked question there are a few other things you can try:
PowerShell says "execution of scripts is disabled on this system."
To summarize from the link:
If you are running from a windows server make sure you set the execution policy on all versions of powershell that you have on the system(both x64 x86 versions of powershell)
OR
Run the following to bypass the Execution Policy:
powershell -ExecutionPolicy ByPass -File script.ps1
I have a power shell script that runs to stop services, 'stop / terminate process' , delete 2 files and then restart.
I can run this script perfect on my Windows 10 64 Bit Host Machine - with ZERO issues.
I try to run it in my Virtual Machines and I get the error
cannot be loaded because running scripts is disabled on this system. For more information, see about_Execution_Policies at https:/go.microsoft.com/fwlink/?LinkID=135170
SO just for giggles I went to see my group policies and they are not configured on either machine.
Administrative Templates > Windows Components > Windows PowerShell
Not Configured.
So why the issue on the virtual machine and not in my host ?
EDIT
Ran Get-ExecutionPolicy and also Get-ExecutionPolicy-List on VM
Restricted
MachinePolicy Undefined
UserPolicy Undefined
Process Undefined
CurrentUser Undefined
LocalMachine Undefined
Ran it on my Host
Scope ExecutionPolicy
----- ---------------
MachinePolicy Undefined
UserPolicy Undefined
Process Undefined
CurrentUser Undefined
LocalMachine Unrestricted
I do not know how my local machine was changed - software installation ??
The following will allow all local scripts to execute on the VM, irrespective of whether they're signed or not:
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine
I am going to go out on a limb here and just rehash a portion of About Execution Policies.
The default execution policy for Windows client OSes is Restricted. This means that a script will not run automatically. If your VM has a Windows client OS and you have never changed the execution policy, then your issue is expected. If the one Windows 10 machine works without issues, then someone changed the execution policy.
On the problematic VMs, you will need to determine the scope (or account) that is running your script. Then you will need to set the execution policy accordingly.
If you are testing running a script while logged into the server as yourself, then you can just open a PowerShell console and run the following:
Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
Then run the script in that same console.
The following command will list the execution policy for all scopes on that machine:
Get-ExecutionPolicy -List
You should compare the command above on the working system and the non-working system. Your issue likely be the execution policy setting for the particular scope that is running the script. If you read the link in my post, it should help you determine what you need to change specifically.
If you are on Windows here is what you have to follow:
Press the [windows] button and then type PowerShell.
Run as Adiministrator
Copy and Paste the following command and hit [Enter]
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine
Type Y and hit [Enter]
Rerun the command and type A hit [Enter]
Close the powershell and try again
Good luck.
Open your PowerShell and enter the following command
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine
I had the same problem with VS Code then I check the cmd with Administrator run. There is no problem so better to use CMD easy way to pass this problem
Run Powershell as an administrator and run the following command:
set-executionpolicy remotesigned
The least problematic approach is to use the command:
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
This will get around Admin user authority issues.
After running powershell as administrator, run the following commands:
Get-ExecutionPolicy -List
Set-ExecutionPolicy Unrestricted
Set-ExecutionPolicy Unrestricted -Force
May be you need to restart the machine.
Open your powershell as an administrator and then paste those commands:
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine
Then choose A
I had the same issue in my PC. Open the windows PowerShell ISE in administrator mode and run Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine
This command solved my issue.
I had same issue when trying to create a vue application by running vue create my-project
To fix this I have followed below steps
Open powershell as an administrator on Windows
Run this command - Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine
Now open a new session on your terminal and run your application specific script. It worked.
user powerShell as admin and execute the following commends:
1-Set-ExecutionPolicy RemoteSigned
2-Get-ExecutionPolicy -List
3-Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine*
and rerun the scrips again and it will work
I m just farwarding all the changes that implies with setting the ExcecutionPolicy to RemoteSigned with the command : Set-ExecutionPolicy -ExecutionPolicy RemoteSigned ( I really recommend to first give a look at the other policies offered : Windows Execution Policies )
RemoteSigned :
The default execution policy for Windows server computers.
Scripts can run.
Requires a digital signature from a trusted publisher on scripts and
configuration files that are downloaded from the internet which
includes email and instant messaging programs.
Doesn't require digital signatures on scripts that are written on the
local computer and not downloaded from the internet.
Runs scripts that are downloaded from the internet and not signed.
Risks running unsigned scripts from sources other than the internet
and signed scripts that could be malicious.
Note that on Windows, browsers sign downloaded files and mark them as 'coming from the Internet'. If u want to unblock such a script, u can use the cmd Unblock-File.
user powerShell as admin and execute the following commends:
PS C:\WINDOWS\system32> Get-ExecutionPolicy -List
Scope ExecutionPolicy
----- ---------------
MachinePolicy Undefined
UserPolicy Undefined
Process Unrestricted
CurrentUser Unrestricted
LocalMachine Unrestricted
To unrestrict the execution policy:
Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Scope Process
Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Scope CurrentUser
Under your normal user. The following requires to open an administrator instance:
Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Scope LocalMachine
as an administrator.
You might need to restart the computer afterwards.
You will see peerjs server is working
Use the syntax below
Set-ExecutionPolicy -Scope CurrentUser
Enter the "Unrestricted" as your value in the ExecutionPolicy parameter syntax below:
ExecutionPolicy:Unrestricted
Then run your command; you can check the node version or any version of the software you installed after implementing the commands above
I have tried these two ways that you can tackle this problem succesfully:
By enabling PowerShell execution policies:
PS C:\Users\usr1>Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted
For example, I encountered this problem when i wanted to run yarn command at my project's root folder. Then by running the command above, I was abled to run the comand yarn without a problem.
Use bash terminal instead of powershell terminal
You can use this method when you get error from the powershell terminal by running the Set-ExecutionPolicy command. Like the error below:
In such case, by switching your terminal to bash you can have your scripts run:
I'm trying to install Chocolatey to use with PowerShell.
The recommended way to install it is copy and paste the following line.
#powershell -NoProfile -ExecutionPolicy unrestricted -Command "iex ((new-object net.webclient).DownloadString('http://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%systemdrive%\chocolatey\bin
But I get the following error:

ExecutionPolicy is set as RemoteSigned and I'm running Powershell v3
I tried some apply some bits of the installation code rather than the whole line, but basically, anything after #Powershell is an unexpected token.
You must start that line from cmd.exe (a "standard" command prompt), not from PowerShell.
In PowerShell v3+ the easiest way is:
Open a PowerShell window (run as administrator)
Check the version of PowerShell is greater than 3:
$PSVersionTable.PSVersion
Enable execution of PowerShell scripts?
set-executionpolicy remotesigned

I was unable to install Chocolatey on my Windows 10 64-bit OS installation. I was getting powershell not recognized as internal or external command. Finally I found the solution, so to people who ever facing the exact same problem as I did, here is the solution for you.
The reason why you get such an error is because the WindowsPowerShell path is not set. So kindly set the Path as
%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\
Go to Environment variable (see below). You see that Path variable, click on Edit and you see one more pop-up window, which shows a couple of paths there. Now click on New and copy-paste the above path. Close your CommandPrompt(admin) and open it again. Run the command given by Chocolatey, and now it starts downloading.
Here is a step-by-step guide:
Go to Control Panel → System → Advanced System Settings → Environment Variables → User variable for Users → Select Path Variable → click Edit → Click on New → paste this %SYSTEMROOT%\System32\WindowsPowerShell\v1.0\ → Click OK → you're done.
