I just want to install flutter correctly on linux , many time I get this Errors:
/home/beit/snap/flutter/common/flutter/bin/internal/shared.sh: line 24: cd: /home/beit/snap/flutter/common/flutter/packages/flutter_tools: No such file or directory
Error: Unable to 'pub upgrade' flutter tool. Retrying in five seconds... (9 tries left)
I saw some solutions for this problem such as deleting the "bin" folder, run pub repair, and stuff
but they could not solve the problem
I just want to start Flutter
note: I download the Dart SDK package many times, and use "flutter doctor"
I use the following command line for installation (as Linux install doc in flutter.dev):
sudo snap install flutter --classic
i found the solution , use manually install to solve this problem
1- first delete your previous version of flutter use :
snap remove flutter
2- next , download flutter SDK from here:
please download stable channel
3- follow this link: if you use Linux
4 - do the optionally step:
flutter precache
done! , you can use "flutter doctor" command line to check other things.
if I Open Vs code and try to code, or try to use the command flutter, flutter doctor etc. in the Terminal, It doesn't work and just says:
Error: Unable to 'pub upgrade' flutter tool. Retrying in five seconds... (9 tries left)
Failed to start the Dart CLI isolate. Could not resolve DartDev snapshot or kernel.
(null).
Later it says in an little Window at the bottom lefthand corner:
Failed to initialize Flutter: Process exited with code 1.
And I use the Mac with Mac chip!
When I try to run any Flutter Command, it gives me this error:
The system could not find the path specified
Error (1): Unable to 'pub upgrade' flutter tool. Retrying in five seconds... (9 tries left)
After that, it waits 5 Seconds and loops. To end the loop it tells me to press CTRL + C.
I've been looking for the solution all day, I've tried the following things:
Reinstalling Flutter, Dart and Android Studio
Adding Flutter to the path
Deleting the cache folder
Disabling Antivirus
Running D:\Flutter\flutter\bin\cache\dart-sdk\bin\pub.bat upgrade --verbosity=error --no-packages-dir in D:\Flutter\flutter\packages\flutter_tools>
Everything didn't work.
As Mentioned, my Flutter SDK path is D:\Flutter\flutter
I installed flutter, dart and the app on my C:\ Drive and it worked for me!
I'm new to flutter and trying to install it by following a video on youtube.
But I'm getting error and cannot proceed.
I'm getting this error,
"Because flutter_tools depends on pubspec_parse 0.1.5 which doesn't
match any versions, version solving failed. Error: Unable to 'pub
upgrade' flutter tool. Retrying in five seconds... (9 tries left)"
Here's what I have done.
vim .bash_profile
changed the path to "export PATH="$PATH:[PATH_TO_FLUTTER_GIT_DIRECTORY]/flutter/bin" (I changed the[PATH_TO_FLUTTER_GIT_DIRECTORY] to my path, something like "user/name/ ... developer/. Also I press I key to insert them. If you know how to fix it, please let me know. I searched on Google but couldn't figure out the solution.

First Make sure you have a working internet connection and if this issue still exists then, this error may be because the dart sdk may have not been properly downloaded.
The simplest solution is to delete the cache folder located in
flutter/bin(location where flutter is installed) and then Run flutter doctor
I fix that by:
Ctrl+C to stop infinite error loop.
Kill the Dart process in Windows Task Manager.
Delete the cache folder located in flutter/bin directory.
Run in command line flutter pub cache repair.
After that I run flutter doctor and get predictable results:
e:\tools>flutter doctor

I found my antivirus blocks pub upgrade,I had same issue while hitting flutter doctor, I turned off my antivirus and tried to run "flutter doctor" again, and worked well!
windows:
simplest and easiest way is download the latest version flutter sdk. replace manually current folder by pasting downloaded flutter folder instead of the current folder
in c drive. always choose replace and paste.
after finishing that check with flutter doctor. my issue solved
Solved this issue when Run the CMD as administrative.
This issue will come in protected network as well as due to anti-virus. Even I was facing the same. I downloaded latest stable version manually from the following link, which doesn't required any update process and it works for now..
Download Link For Flutter in Zip format
I updated the flutter SDK via git pull, then the flutter doctor command works.
Just delete the cache folder in flutter/bin and run flutter doctor again!!
Just Deactivate your antivirus and run it again. It would work fine. I had the same issue before.
I deactivated my antivirus for some time and executed flutter doctor command once again in cmd and got fruitful results after hours of patience.
One more thing to note, you should ensure that path of dart-sdk folder should be added to the path in user variables.
It seems it is not being able to "unzip" the downloaded Dart file because it misses 7-zip uncompressor.
I installed it and it worked! It will deal with .7z files.
I hope it works for other people too!!
I had the same problem and it was solved.
Steps:
Download Dart and Filters SDK then Decompress these files and move them to this directory.
C: \
Define the variables in path:
Delete cache directory in flutter/bin
Then run flutter doctor
Make sure you downloaded the windows powershell i use windows 8 it wasn't installed by default , when i downloaded it it worked for me.
Check your flutter bin path in environment variable(User Variables). If not go to Under User variables check if there is an entry called Path:in that add this flutter/bin path.
Strangly when I kill the dart process in Windows Task Manager it is working. But sometimes even when dart process is running update working.
I had to turn off the Android Emulator. It was running for me...
I got the same error and was not able to get rid of it. So I deleted the flutter and instead of cloning it I downloaded the zip from the flutter website and extracted it. Now it works just fine.
Manually downloading the SDK from flutter website fixed the issue.
Still dont know why this problem occured tho.
If you are using Avast (or possibly some other anti virus too) on Mac and have recently updated the OS to Big Sur then follow the below steps to fix this issue
Open Avast and in the Web Shield area disable the "Scan secure connection".
Run flutter config --no-analytics and then run pub upgrade.
This should probably fix the issue.
You can also refer to below threads in Github for more details about the cause
https://github.com/flutter/flutter/issues/40515
https://github.com/flutter/flutter/issues/68999
In my case, the error resolve after adding below folder into exclude option in anti virus
Flutter SDK location
D:\Android\flutter_windows\flutter\*.
Flutter Local Pub folder
C:\Users\hitesh\AppData\Local\Pub
You get the error --
"Pub failed to delete entry because it was in use by another process.
This may be caused by a virus scanner or having a file
in the directory open in another application.
Error (1): Unable to 'pub upgrade' flutter tool. Retrying in five seconds... (1 tries left)" even if you are in one of the flutter directories from Windows explorer. Close the window and try running Flutter doctor. This will resolve.
If anyone faces this problem on macOS with AdGuard installed. Try this:
Go AdGuard Preferences -> Network -> Automatically filter applications -> Select Mode... and change mode to Automatic Proxy.
Pub failed to delete entry because it was in use by another process.
This may be caused by a virus scanner or having a file
in the directory open in another application.
Error (1): Unable to 'pub upgrade' flutter tool. Retrying in five seconds... (9 tries left)
Tried switch to Dev channel and got stuck with "Unable to pub upgrade". Did everything and nothing worked.
This is what I did:
Renamed the Flutter SDK folder
Download the latest Flutter SDK
Extract to the same location of previous renamed SDK
Flutter channel Dev
Flutter upgrade
And everything back to normal.
Source of Problem
It might be possible that you don't have enough free disk space. That's what caused my problems to begin with.
Solution
In my case,
First I had to clean up space to remove any unused files.
Then I had to overwrite the flutter SDK folder due to corruption. The SDK can be found here.
I had the same issue with my MacBook M1. I tried deleting and running flutter pub cache repair But It didn't work for me.
Then I ran the command softwareupdate --install-rosetta and accepted the software licences & agreement (After installing XCode). Now the command flutter works fine. :)
Tried all of the above without success. The search order in the PATH system variable turned out to be the problem:
it was:
G:\My Drive\Compilers\flutter\bin;
G:\My Drive\Compilers\flutter\bin\flutter;
G:\My Drive\Compilers\flutter\bin\flutter.bat;
G:\My Drive\Compilers\flutter\bin\dart.exe;
G:\My Drive\Compilers\flutter\bin\dart;
G:\My Drive\Compilers\flutter\bin\dart.bat;
changed it to:
G:\My Drive\Compilers\flutter\bin\flutter
G:\My Drive\Compilers\flutter\bin\flutter.bat
G:\My Drive\Compilers\flutter\bin\dart
G:\My Drive\Compilers\flutter\bin\dart.bat
that fixed it
Mac auto iCloud upload might be causing the error
If you are using Mac and if your Desktop files are being uploaded to iCloud automatically, sometimes iCloud uploads the "bin" file or the "cache" file inside the flutter file. I've just downloaded the file onto desktop (right click the file -> "Download Now") and it downloaded the file, it ran as usual. (Automatic upload can be turned off from system preferences if youn are getting this error frequently like I was).
For my case, i was using ubuntu, and after reading the above comments, i have come to a resolution that the above error comes as a result of permissions being blocked, accessing cmd with admin access levels solves the problem, e.g on linux run sudo flutter doctor and the problem will be solved.
This error occured to me when i tried upgrading my flutter so it needed admin rights to be upgraded nothing much
