I am using Python 3.7 for my project. Then when I tried to do

```
edamame$ git commit --amend --no-edit

```

I got the follow error (`git status` works fine though): 

```
Your PYTHONPATH points to a site-packages dir for Python 3.x but you are running Python 2.x!
     PYTHONPATH is currently: "/Users/edamame/tools/sim/scripting/:/usr/local/lib/python3.7/:/usr/local/lib/python3.7/site-packages/"
     You should `unset PYTHONPATH` to fix this.

```

I tried the below but no luck:

```
edamame$ pip3 install git

Collecting git
  Could not find a version that satisfies the requirement git (from versions: )
No matching distribution found for git

```

So I have to set the PYTHONPATH each time manually like below, which is very inconvenient. Any advise? Thanks!

```
edamame$ export PYTHONPATH=

```
