The log seems to complain about this line: git log -n 1 --pretty=format:%ad --date=iso, but the command here works from my terminal.

[jonahwilliams]

What version of git do you have?

Also various build errors on 10.15

[stuartmorgan-g]

@AppleEducate Supporting Catalyst for iOS Flutter projects is completely unrelated to being able to run Flutter commands on 10.15.

I can't find the issue at the moment, but I know I've seen a bug about git failing after an OS update until you install command line tool support; this is likely a dup of that.

Edit I may be thinking of #28939 but I thought there was something clearer. Although if it runs successfully from the terminal, maybe not the same issue.

What does echo $? show after you run the git command directly? Maybe there's a bug and it's returning a bad exit code even though it's running successfully?

@timsneath
I'm using macos 10.15.
Though I've found several errors when running flutter with macos 10.15&ios13, however, this issue doesn't appear in myside.
It seems probably a git issue which may not related to 10.15.

[mclark4386]

did you install git from homebrew?

[rishabnayak]

look at #33909 for solutions!

[timsneath]

@stuartmorgan The command

git log -n 1 --pretty=format:%ad --date=iso

pipes to less on my machine. But

echo `git log -n 1 --pretty=format:%ad --date=iso`

returns a meaningful result (an ISO-formatted date) with an error code of 0.

Looking at my machine, I have two versions of git installed:

$ where git
/usr/local/git/current/bin/git
/usr/bin/git
$ /usr/local/git/current/bin/git --version      
git version 2.19.0.605.g01d371f741-goog
$ /usr/bin/git --version
git version 2.20.1 (Apple Git-117)

The Google one is first on the path:

$ git --version      
git version 2.19.0.605.g01d371f741-goog

[stuartmorgan-g]

echo git log -n 1 --pretty=format:%ad --date=iso
returns a meaningful result (an ISO-formatted date) with an error code of 0.

The error code of that command is echos error code though, not git's.

We should probably investigate further offline.

I'm having other weird problems with Catalina as well. Most of the apps after the upgrade now request you access to do something. Then you need to go to Preferences and allow them on Security section.

flutter cli was no different. Except that it is now ranging on the snapshot and I can't run it anymore... So VSCode don't work as well...

Click on Open Anyway doesn't do anything :(

Any clues?

Thanks!
