Could not detach head

[Helen Xu]

I have this error when I tried to commit a change on SourceTree and tried to pull or push the change: is there anyone can help me?

Hi Helen,

This is the error from the output that indicates the cause of this issue:

Filename too long

This comes from a limitation in Windows as it does not properly support files and directories longer than 260 characters.

In order to solve this, you can change the Git configuration by executing the following command in a terminal/Git Bash:

git config --system core.longpaths true

This will apply to all users on the Windows machine and it will allow file paths of 4096 characters.

You can also configure it for your Windows user only with the command

git config --global core.longpaths true

You can find more info on the following knowledge base article. This article is from Bamboo knoweldge base, but it applies in cases where Bamboo is not used.
