Developer Discussion

When using pub or flutter to install libraries it fails with errors like this:

$ flutter packages get
gzip: warning: <stdin>: trailing junk was ignored                       
gzip: warning: <stdin>: trailing junk was ignored                       
tar: Child returned status 1                                            
tar: Error is not recoverable: exiting now                              
tar: Child returned status 1                                            
tar: Error is not recoverable: exiting now

tar: Error is not recoverable: exiting now                              
gzip: warning: <stdin>: trailing junk was ignored

In Clear Linux pigz is installed and it wraps gzip and gunzip.

The flutter and pub tools require the streaming functionality that real gunzip provides.

To resolve I installed brew for linux. Then ran brew install gzip and then make sure the brew path is preferred in my $PATH.

Yes, pub was able to install stagehand and the webdev server.

All good!

I will add that the initial ‘compilation’ of the stagehand
AngularDart app with webdev on Windows 10 took 2 minutes 40 seconds and on Clear Linux it took 2 minutes 4 seconds on this Core m3 laptop. The whole development cycle is much quicker.

Yes. brew install gzip and add gzip path before $PATH in bashrc to resolve all issues faced in flutter related to gunzip

Got the same problem today, /bin/tar works wrong :frowning:

flutter pub get -v 
....
[        ] IO  : Spawning "/bin/tar --warning=no-unknown-keyword --extract --gunzip --no-same-owner --no-same-permissions --directory /home/ice/development/flutter/.pub-cache/_temp/dirSYQITT" in
/home/ice/AndroidStudioProjects/pet_pro/.
[  +23 ms] gzip: warning: <stdin>: trailing junk was ignored
[        ] /bin/tar: Child returned status 1
[        ] /bin/tar: Error is not recoverable: exiting now

@nopro404 thanks for workaround!
