If you run Windows 10 Home Edition you could change you Registry to enable Long Paths.

Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem in regedit and then set LongPathsEnabled to 1.

If you have Windows 10 Pro or Enterprise you could also use Local Group Policies.

Go to Computer Configuration > Administrative Templates > System > Filesystem in gpedit.msc, open Enable Win32 long paths and set it to Enabled.

git config --system core.longpaths true
