您应该在您有写入权限的目录中执行命令。所以：

  cd〜/ 
 mkdir code 
 cd code 
 git clone https：/ /github.com/kivy/kivy 
 

例如。

I'm trying to clone my fork of the kivy git, but it's not working. I've made the fork correctly, I believe, but when I type this into my Mac terminal:

git clone https://github.com/mygitusername/kivy.git

I get this error:

fatal: could not create work tree dir 'kivy.: Permission denied

Anyone see what I am doing wrong? Thanks!

You should do the command in a directory where you have write permission. So:

cd ~/
mkdir code
cd code
git clone https://github.com/kivy/kivy

For example.
