For context, I’m trying to activate a virtual environment, and then run my python script from within that venv, all in one powershell session. I’m doing this in a .bat file that I will later start as a service (The whole point of this is to run main.py in the venv as a windows service)
I tried this:
powershell -noexit -file C:\MyPythonProject\venv\Scripts\Activate.ps1; python C:\MyPythonProject\main.py
This doesn’t seem to work. Only the first command (to activate the venv) works. What am I doing wrong?
use & to chain commands:
powershell -noexit -file C:\MyPythonProject\venv\Scripts\Activate.ps1 & python C:\MyPythonProject\main.py

Powershell workflow is not supported in powershell 32bit mode. Thus i want to execute the script using powershell 64bit mode.How to run .ps1 script in 64bit mode via jenkins?
You could create your custom powershell step like in this stackoverflow answer
Executing powershell command directly in jenkins pipeline
You'll have to replace powershell.exe by the path to your powershell 64b exe
You could also use a shebang. some literature on that at How can I use a shebang in a PowerShell script?
it works by calling using c:\windows\sysnative\WindowsPowerShell\v1.0\powershell.exe instead of c:\windows\system32\WindowsPowerShell\v1.0\powershell.exe
find more information about sysnative at https://www.thewindowsclub.com/sysnative-folder-in-windows-64-bit
I confirm that calling:
%SystemRoot%\sysnative\WindowsPowerShell\v1.0\powershell.exe -executionpolicy Unrestricted -file "%~dp0\file.ps1"
results in the 64 bit powershell.
One can validate inside their script by printing out debug of:
$GE_64BitPS_Status=[System.Environment]::Is64BitProcess
write-host $GE_64BitPS_Status
I am calling the below script in my post build configurations:
%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe -NoProfile
-ExecutionPolicy RemoteSigned -file "\Sclddev8\tfs\Scripts\slack-notice.ps1" -Verb RunAs;
However, I keep getting this error:
Send-SlackMessage : The term 'Send-SlackMessage' is not recognized as the name
But I have installed this module in my environment and if I open a PowerShell console or run the file outside of this build process, works without issue.
When you install a Powershell module, you are technically importing the module from your profile every time you open a new Powershell window. By running Powershell with the "-NoProfile" switch, you're preventing the module from being imported (even though it's "installed" and the files are present).
What may be your best option, if you want to keep the "-NoProfile" switch active, is to have a line at the top of your script to import the module before continuing. If you're using Warren Frame's "PSSlack" module, the command you need is:
> Import-Module PSSlack
I hit the same issue.
What helped was... copying the folder into C:\Windows\SysWOW64\WindowsPowerShell\v1.0\Modules.
Yup, it makes a difference.
I have an powershell script saved in a .cmd file that downloads a file from the web and then unzips it. My azure web role executes it upon startup. This is the script:
powershell -ExecutionPolicy Bypass -c $(New-Object Net.WebClient).DownloadFile('URL.zip', 'FILE.zip') ;
(New-Object -com shell.application).namespace('c:\FOLDER').Copyhere((New-Object -com shell.application).namespace('FILE.zip').items())
When I run the script via Azure startup tasks:
The first part of the script works. The file is downloaded. The second part of the script which unzips does not run.
When I run the script via the command line when remoted into the VM:
The entire script runs.
I therefore know this is not a syntax error. The only difference I can think of between the two cases above is a permissions issue. But, I am running powershell with -ExecutionPolicy set to Bypass, which is the highest permission level. Anybody have any ideas? Thanks!
Change the command so that the output of the command is dumped into a file. Something like this should work
<YOUR_COMMAND> > out.log 2> err.log
Run the task again and checkout the output in the logs.
Also, you are using relative paths rather than absolute ones. The scheduled task probably run with the windows system folder as its working directory, so you may be getting a permissions error from that. Try using an absolute path to a directory you created.
I'm using Hudson version 1.324 for CI and have a couple of issues:
Environment:
Windows Server 2008
Powershell v1.0
Hudson 1.324 running as a service
Hudson Powershell Plugin installed
Psake (aka. "Powershell Make/Rake" available from Github) 0.23
(All current/latest versions as of this initial post)
I have a Powershell (PS) script that works to compile, run NUnit tests, and if successful, create a 7z file of the output. The PS script works from the command line, on both my local development box as well as the CI server where Hudson is installed.
1) Execution Policy with Powershell.
I initially ran a PS console on the server, ran Set-ExecutionPolicy Unrestricted, which allows any script to be run. (Yes, I realize the security concerns here, I'm trying to get something to work and Unrestricted should remove the security issues so I can focus on other problems.)
[This worked, and allowed me to fire off the PS build script from Hudson yesterday. I then encountered another problem, but we'll discuss that more in item #2.]
Once Hudson could fire off a PS script, it complained with the following error:
"C:\Windows\system32\WindowsPowerShell\v1.0\powershell "&
'OzSystems.Tools\psake\psake.ps1' '.\oz-build.ps1'" The term
'OzSystems.Tools\psake\psake.ps1' is not recognized as a cmdlet, funct
ion, operable program, or script file. Verify the term and try again.
At line:1 char:2
+ & <<<< 'OzSystems.Tools\psake\psake.ps1' '.\oz-build.ps1'"
Using the same command line, I am able to successfully execute the PS script from the command line manually. However Hudson is unable to get PS to do the same. After looking at additional PS documentation I also tried this:
"& 'OzSystems.Tools\psake\psake.ps1' '.\oz-build.ps1'"
and got a similar error. There does not appear to be any documentation for the Powershell plugin for Hudson. I've gone through all the Powershell plugin files and don't see anything that's configurable. I can't find a log file for Hudson to get additional information.
Can anyone help me past this?
2) I spent yesterday wrestling with #1. I came in this AM and tried to dig in again, after restarting the Hudson server/service, and now it appears that the ExecutionPolicy has been reset to Restricted. I did what worked yesterday, opened a PS console and Set-ExecutionPolicy to Unrestricted. It shows Unrestricted in the PS console, but Hudson says that it doesn't have rights to execution PS scripts. I reopened a new PS console and confirmed that the ExecutionPolicy is still Unrestriced -- it is. But Hudson evidently is not aware of this change. Restarting Hudson service again does not change Hudson's view of the policy.
Does anyone know what's going on here?
Thanks, Derek
I just ran into the problem of running powershell scripts in hudson. The thing is that you are running a 32-bit process of Java, and you've configured Hudson for 64-bit but not for 32-bit. See the following thread we created at microsoft.
http://social.technet.microsoft.com/Forums/en/winserverpowershell/thread/a9c08f7e-c557-46eb-b8a6-a19ba457e26d
If your lazy.
1. Start powershell (x86) from the start menu as administrator
2. Set the execution policy to remotesigned
Run this once and your homefree.
When Running PowerShell from a scheduled task or Hudson you want to:
Specify the -ExecutionPolicy parameter (in your case: -Ex Unrestricted)
Specify that command using either -Command { ... } or -File NOT BOTH and not without specifying which you mean.
Try this (except that I don't recommend using relative paths):
PowerShell.exe -Ex Unrestricted -Command "C:\Path\To\OzSystems.Tools\psake\psake.ps1" ".\oz-build.ps1"
To be clear, this will work too:
PowerShell.exe -Ex Unrestricted -Command "&{&'OzSystems.Tools\psake\psake.ps1' '.\oz-build.ps1'}"
The first string after -Command is interpreted as THE NAME OF A COMMAND, and every parameter after that is just passed to that command as a parameter. The string is NOT a script, it's the name of a command (in this case, a script file)... you cannot put "&'OzSystems.Tools\psake\psake.ps1'" but you can put "OzSystems.Tools\psake\psake.ps1" even if it has spaces.
To quote from the help (run PowerShell -?) emphasis mine:
-Command
Executes the specified commands (and any parameters) as though they were
typed at the Windows PowerShell command prompt, and then exits, unless
NoExit is specified. The value of Command can be "-", a string. or a
script block.
If the value of Command is "-", the command text is read from standard
input.
If the value of Command is a script block, the script block must be enclosed
in braces ({}). You can specify a script block only when running PowerShell.exe
in Windows PowerShell. The results of the script block are returned
to the parent shell as deserialized XML objects, not live objects.
If the value of Command is a string, Command must be the last parameter
in the command , because any characters typed after the command are
interpreted as the command arguments.
I have been having the same problems as you (as you've seen from my comments). I have given up on the powershell launcher and moved to running things using the batch file launcher. Even though I had set the system to unrestricted that setting didn't seem to matter to hudson's launcher. I don't know if it runs in some other context or something, even adding things to the global profile.ps1 didn't seem to help. What I ended up doing was running
powershell " set-executionpolicy Unrestricted; & 'somefile.ps1'"
which does what I need, although it isn't ideal. I've e-mailed the plugin author about this and will update.
For question #1, try this (assuming you are using PowerShell 2.0):
"C:\Windows\system32\WindowsPowerShell\v1.0\powershell -executionPolicy Unrestricted -file OzSystems.Tools\psake\psake.ps1 C:\{path}\oz-build.ps1"
You are using "." for the path to oz-build.ps1. I suspect you will need to provide the full path to your oz-build.ps1 file to make this work. Unless the infrastructure that executes the command above happens to have the current dir set correctly. And even if it is set correctly for the "process", that only matters to .NET/Win32 API calls and not to PowerShell cmdlets. Current dir in PowerShell is tracked differently than the process's current dir because PowerShell can have multiple runspaces running simultaneously. That sort of global, mutable value doesn't work in this concurrent scenario.
As for question #2, what account does the Hudson service run under? Make sure that account has executed Set-ExecutionPolicy RemoteSigned (or unrestricted).
I just got through this exact problem. What a pain!
If you are running a 32-bit JVM on a 64-bit Windows, make sure that you set the execution policy for the 32-bit Powershell interface. I found my 32 bit executable here:
C:\Windows\syswow64\Windowspowershell\v1.0\powerhsell.exe
The 32- and 64-bit Powershell environments are completely distinct so setting the execution policy in one has no effect on the other.
