[sinadarvi]

i've got error like this when trying to install flutter.
i run
flutter doctor
and suddenly i got error like this :

This is an unexpected error. Please run

    pub --trace upgrade --verbosity=error --no-packages-dir

and include the logs in an issue on https://github.com/dart-lang/pub/issues/new

What Flutter version are you using?
flutter --version

[sinadarvi]

@zoechi i got clone of the flutter repo today for installing it and i wasn't able to install it...and when i tried to run flutter --version i got above error

[zoechi]

Sounds like a network issue
You don't have by any chance a space in the Flutter install directory path?

[sinadarvi]

yes, i just update my answer ... i got above error again trying to get version...
and i have enough space in install directory path for installation

[sinadarvi]

@zoechi even deleting pub cache wasn't helpful. any idea ?

[zoechi]

I wouldn't expect deleting pub cache to have effect

[nex3]

This issue was moved to flutter/flutter#15948

[zoechi]

@nex3 @natebosch can this issue be reopened here? It looks like this error is caused by invalid pubspec.yaml and there should be a better error message from pub.

I saw an example where the first line had a few spaces before name: ... and flutter/flutter#15948 mentions examples with invalid path: ...

People run into this quite often.

cc @mit-mit to triage

[zoechi]

There are actually 2 different cases (which I wasn't aware before)

Could not find a file named "pubspec.yaml"

A few I found in a Google search. Some are older but I think they show that in many situations the error message is not helpful. Perhaps there is a way to get more information about the root cause.

• MacOS Error: Could not find a file named "pubspec.yaml" in build#1469
• Could not find a file named "pubspec.yaml" in "...pub.dartlang.org/archive-2.0.4". flutter/flutter#22175
• Could not find a file named "pubspec.yaml" fluttercommunity/flutter_launcher_icons#50
• Could not find a file named "pubspec.yaml" in "../.pub-cache/hosted/pub.dartlang.org/term_glyph-1.0.0". flutter/flutter#16100
• https://stackoverflow.com/questions/27217278/could-not-find-a-file-named-pubspec-yaml-in
• https://stackoverflow.com/questions/52202923/flutter-running-flutter-fails-could-not-find-a-file-named-pubspec-yaml-upd?rq=1
• https://stackoverflow.com/questions/51317203/could-not-find-a-file-named-pubspec-yaml-in-users-username
• https://stackoverflow.com/questions/42209519/could-not-find-a-file-named-pubspec-yaml-in-home-vagrant-pub-cache-hosted-p
• https://intellij-support.jetbrains.com/hc/en-us/community/posts/207306545-Dart-Could-not-find-a-file-named-pubspec-yaml-

Update Seems there is another source of this error
caused by Chinese Pub mirror server being down or not responding properly for some other reason

• Could not find a file named "pubspec.yaml" in "C:\flutter\bin\cache\dart-sdk\bin" #2076 (no valuable information but from the timing probably the same as
• flutter create xxx #2078
• Error when pub upgrade flutter tool #1812

This is another open Pub issue with the same error

• pubspec.lock is different between Windows and Unix if path reference is used #950 (comment) (pubspec.lock is different between Windows and Unix if path reference is used)

and there is a similar error message

Error: No pubspec.yaml file found.

• flutter packages pub publish "no pubspec.yaml file" when pubspec.yaml is present flutter/flutter#21305
• error message displayed when trying to run 'flutter packages pub global activate <tool>' flutter/flutter#27911
• "Error: No pubspec.yaml file found" When project located in OneDrive flutter/flutter#17650
• Flutter test driver break TextField flutter/flutter#17472

which looks like it comes from Flutter https://github.com/flutter/flutter/search?q=%22No+pubspec.yaml+file+found%22&unscoped_q=%22No+pubspec.yaml+file+found%22

I just put this here to gather more information and perhaps find a pattern.

@zoechi did you come across a simple repro for this?

[zoechi]

@mit-mit no, every attempt to reproduce failed so far.

There were 2 cases where fixing the content of pubspec.yaml seems to have solved it, but I wasn't able to reproduce that way.

Most other cases were broken ~/.pub-cache or where some radical actions like reinstalling Flutter seems to have fixed it.

Simple write in terminal ,
cd your project name // for windows
flutter run // use for run your application .
