Windows batch script to install locally-saved Python packages into a virtual environment

A hacky script to install Python packages from local wheels / tarballs. pip should do this by retrieving remote files, but if you're behind a firewall, you can use this instead.

• Find and download packages - ideally platform-specific wheel (.whl) files from: https://pypi.python.org/pypi
• set the path and name of your desired venv on line 6.
• package_names_in_order.txt lists files in a specific order, to enable installing requirements in the correct dependency order.
• /packages/ subdirectory (located relative to the .bat script dir) can contain anything pip accepts: .whl; .tar.gz; ...
• If you don't require a specific installation order, you can just use (note this is only for .whl files): for %%f in ( %~dp0\packages\*.whl ) do ( echo "installing %%~f" pip install %%~f ) in place of the package_names_in_order.txt line.

install_python_packages.bat

REM    Windows batch script to install local Python packages into a virtual environment.
REM    Alongside the script should be "sources" and "packages" subdirectories.
REM    'sources' can contain unzipped folders, each containing a 'setup.py' file;
REM    'packages' can contain anything acceptable for pip install. (*.whl; *.tar.gz)
REM    User should supply 1 argument, the new virtual env's name.

@echo off

set venv_root_dir="C:\Python3\virtual-envs"

if [%1]==[] goto usage

REM	set venv_name=env-test
set venv_name=%1
set venv_install_dir=%venv_root_dir%\%venv_name%

cd %venv_root_dir%
python -m venv %venv_name%

call %venv_install_dir%\Scripts\activate.bat

REM     loop over subdirectories of 'sources'
for /D %%a in (%~dp0\sources\*) do (
    echo "%%a"

    Start /WAIT cmd /k "cd /d  %venv_install_dir%\Scripts & activate & cd /d %%a & python setup.py install & cd /d %venv_install_dir%\Scripts & deactivate & exit 0"
)

call %venv_install_dir%\Scripts\activate.bat

for /F "tokens=*" %%A in (%~dp0\package_names_in_order.txt) do (
    pip install %~dp0\packages\%%A
)

REM alternatively install all *.whl files:
REM for %%f in ( %~dp0\packages\*.whl ) do (
REM     echo "installing %%~f"
REM     pip install %%~f
REM )

pip freeze > %venv_install_dir%\pip-freeze-%venv_name%.txt

call %venv_install_dir%\Scripts\deactivate.bat

exit /B 1

@echo Usage: %0 ^<New venv name^>
exit /B 1

python-virtualenv-script.bat

REM    Windows batch script to run a Python program within its virtual environment. This can be called from Windows Task Scheduler.

set venv_root_dir="C:\Path\to\venv\root"

cd %venv_root_dir%

call %venv_root_dir%\Scripts\activate.bat

call %venv_root_dir%\Scripts\deactivate.bat

exit /B 1

Hey. I think installing Python entirely with a batch script would be too complex. Instead you should look at bundling Python and your script into a single executable. You do this on your machine and send the executable to the other systems which will run it. Have a look at https://www.py2exe.org/ and the other answers here: https://stackoverflow.com/questions/5458048/how-can-i-make-a-python-script-standalone-executable-to-run-without-any-dependen . Hope that helps a bit!
