Version

Description

Melos throw this error while bootstrap project using melos bs melos cli is /Users/evaisse/.pub-cache/bin/melos But it looks like the path extract by utils.getMelosRoot() gives /root/.pub-cache/hosted/pub.dartlang.org/melos-2.3.1

Generating IntelliJ IDE files...

This looks like you have multiple Dart SDKs with different .pub-cache locations, where one cache contains the right version of melos, but somehow another is resolved at runtime.

Could you run which -a dart to check which Dart SDKs are on the path?

[Salakar]

Are we also correctly handling the PUB_CACHE env variable in our check to file the melos lib path?

[blaugold]

We are using Isolate.resolvePackageUri. Not sure how that works internally, though.

[evaisse]

which -a dart resolution is : /usr/local/opt/flutter/bin/dart and no PUB_CACHE in my env.

[blaugold]

The default location for .pub_cache is $HOME. So, if melos looks for files in /root/.pub-cache, that hints to an issue related to sudo or some other way that melos is executing as root, which you probably don't want to do.

Maybe reinstalling melos helps 🤷

hello sir, how to reinstall melos?

[blaugold]

Please try the following commands:

dart pub global deactivate melos
# Also clean the pub cache in case it is corrupted.
dart pub cache clean
dart pub global activate melos

[abdulrojakdev]

Please try the following commands:

dart pub global deactivate melos
# Also clean the pub cache in case it is corrupted.
dart pub cache clean
dart pub global activate melos

Sorry, I want to ask something, I hope you like it. in my project using melos, i have done some melos command in my project. one time I found an error like in the picture. The weird thing is that the darts plugin is the latest and my android studio is also the latest version. the error only appears in the project and if I open the project in visual studio the error does not appear. Sorry, I'm asking like this because at first I was interested in the comments about reinstalling Melos. I'm afraid my problem occurs because of melos, because I've gotten this error twice.

@evaisse is this still happening? Did you perhaps run it with sudo like blaugold suggested?
