Installing multiple python versions on windows

Question

I installed python 3.4 and python 3.5 to C:\Python34 and C:\Python35 respectively. and I created two bat files refering to these executables namely python.bat and python35.bat and added them to my PATH. so that I can get

C:\>python -V 
Python 3.4.3

C:\>python35 -V
Python 3.5.1

C:\>pip

This works fine for me, except when I want to call PIP because it is actually inside the PythonXX\Scripts\ folder.

Is there an easy way to get away with calling pip and other scripts from cmd, without typing C:\>Python34\Scripts\pip or C:\>Python35\Scripts\pip each time?

(Note: pip is not the only file I want to run from Scripts folder. can I do the alias for the Scripts directory?)

couldn't you do the exact same thing than with the python executable? — tglaria

Do something like set PATH=C:\Python35\Scripts;%PATH% in your bat file — J.J. Hakala

@J.J.Hakala would that be a permanent change or for a single session only? (If it's permanent, you would be updating PATH for each time you load the bat file — tglaria

@Zetys I was hoping to find a solution on the directory level, so that I dont need to rename all executables inside Scripts (pip and others) — Ahmad Abdelghany

FWIW, I have a pip2.7.exe in my c:\Python\Scripts and a pip3.5.exe in my c:\Python3\Scripts folder so I can be explicit about which one I want at the command line. — martineau

You can create symbolic links:

for %A in (c:\Python34\Scripts\*.exe) do mklink C:\Windows\System32\%~nA34.exe %A

Then call pip with pip34. Do the same thing with other python versions.

is there a way to make an alias for the Scripts directory, so it works for all executables inside it?

Ahmad Abdelghany Over a year ago

not exactly what i was hoping for as it still alias the .exe files not the directory. (for example won`t work if .exe is in sub directory of Scripts). still useful though. thanks +1

You could set up some aliases

doskey pip34=C:\python34\scripts\pip
doskey pip35=C:\python35\scripts\pip

I don't have a windows shell to test this on, but from what I've read it "should" work.

There are multiple files inside scripts. so I am searching for a solution for the whole directory. I have updated the question to clarify this point
