Installing python with path variables via batch script

Question

I'm trying to install python and 1 pypi module programmatically via a batch script, to allow me to run a script I wrote that needs that module, on several PCs. A batch script will make it easier to install. I have tried

    \\server\share\python-3.6.1.exe /quiet InstallAllUsers=1 Include_pip=1 Include_test=0 PrependPath=1
    python -m pip install utm
    pause

Without success. When run, this throws the error ‘python’ is not recognized as an internal or external command. I realize this means the system path variables have not been updated correctly, but I thought PrependPath=1 was setting these variables correctly. Any help anyone could provide would be appreciated.

You have to close cmd and open a new instance of cmd to get the new PATH value. — DavidPostill

PrependPath will add to the path, you have to re-read the path again in order for the command to work.

You can re-read the path by using RefreshEnv.cmd from chocolatey, or simply customize the path for the installation, and then pass the full path to the Python executable, like this:

\\server\share\python-3.6.1.exe /quiet InstallAllUsers=1 TargetDir=%ProgramFiles%\Python3.6 Include_pip=1 Include_test=0 PrependPath=1
%ProgramFiles%\Python3.6\python.exe -m pip install utm

This almost worked. However, it installed python in C:\program\ and gave me the error message C:\program is not a recognized command.

Ah of course, Windows. You can try running the command via PowerShell, or simply use a non-spaced path, like TargetDir=C:\Python\Python3.6

Thanks! I really appreciate it. I'll test this later tonight then mark it as solved.

Worked like a charm. Thank you very much for your help.

Or just add the required quotes, e.g. set "TARGETDIR=%ProgramFiles%\Python3.6" and install to TargetDir="%TARGETDIR%" and run "%TARGETDIR%\python.exe" -m pip install utm.
