Python will not run in git bash (Windows). When I type python in the command line, it takes me to a blank line without saying that it has entered python 2.7.10 like its does in Powershell. It doesn't give me an error message, but python just doesn't run.

I have already made sure the environmental variables in PATH included c:\python27. What else can I check?

A session wherein this issue occurs looks like the following:

user@hostname MINGW64 ~
$ type python
python is /c/Python27/python
user@hostname MINGW64 ~
$ python

...sitting there without returning to the prompt.

Temporary solution

Just enter this in your git shell on windows - > alias python='winpty python.exe', that is all and you are going to have alias to the python executable. This alias will be valid for the duration of the shell session.

winpty is a Windows software package providing an interface similar to a Unix pty-master for communicating with Windows console programs.

Permanent solution

Add the command to your .bashrc in the users home directory. You can use the CLI or a text editor:

Using CLI

This can be accomplished from git bash like so:

echo "alias python='winpty python.exe'" >> ~/.bashrc

which will create .bashrc in the current users home directory if the file doesn't exist or append the alias to the end of .bashrc if it does.

Using a text editor

Alternatively, you could first create a .bashrc. Depending on your file manager, this may be easier to accomplish in git bash like so:

cd ~
touch .bashrc

At which point you can open .bashrc in your prefered text editor and add it there.

To apply the change, either use the command source .bashrc or restart the shell.

Update

Newer versions of Git no longer use .bashrc but instead use .bash_profile. Conda also uses this profile when initializing, so be sure not to overwrite or delete the initialization block. See more here: Git for Windows doesn't execute my .bashrc file.
