Embedded Python install manually package without pip

Question

I download and unzip python-3.9.6-embed-amd64.zip file from python.org . Then, I unzipped python39.zip and I found site-packages folder in there.I added manually pandas package from pypi. Lastly, I tried this command: python.exe setup.py install . But it doesnt work. How can I install manually a package embedded python ? I want to import that for my script.

On Windows you can use a simple cmd file that install the embeddable and add the pip to the installation. Then you have the portable embedded with pip to install whatever new package. This example will use the windows tools like curl and tar and cache the embeddable zip and get-pip.py to accelerate future installations. Just providing a command line with a specific version and installation path like:

  Install_python_embeddable.cmd 3 11 8 python_env

The script can be this:

@echo off
setlocal enableDelayedExpansion
pushd "%~dp0"

rem arguments
set major_v=%~1
set minor_v=%~2
set micro_v=%~3
set python_folder=%~4
set force_clean=%~5

rem default values
if [!major_v!]==[] set major_v=3
if [!minor_v!]==[] set minor_v=11
if [!micro_v!]==[] set micro_v=8
if [!python_folder!]==[] set python_folder=python_env
if NOT [!force_clean!]==[1] set force_clean=0

rem Composed variables
set python_version=!major_v!.!minor_v!.!micro_v!
set python_id=!major_v!!minor_v!
set python_artifact_file=python-!python_version!-embed-amd64.zip
set python_artifact_path=%~dp0\!python_artifact_file!
set cache_folder=%LOCALAPPDATA%\environmentInstall_packages\PYTHON_EMBEDDABLE

rem Check force clean
if [!force_clean!]==[1] (
    echo ++ Remove old embeddable installation [!python_folder!]
    rd /q /s !python_folder!  > nul 2>&1
)

if exist !python_folder!\Scripts\pip.exe (
    if exist !python_folder!\python!python_id!.pth (
        if exist !python_folder!\Python_!python_version!.txt  goto already_exist_python
    )
)
    rem Install an embedded python
    echo.&echo ++ Install the Python_!python_version! on !python_folder! with pip

You can download manually a tar.gz file when you don't want to use pip from pypi.org. Then you just need it to extract it in Windows PowerShell: tar -xvzf C:\Users\USERNAME\Downloads\FILENAME.tar.gz -C C:\Users\USERNAME\Downloads\FILENAMEDIR as 1st path is from and 2nd one path to. Then you just navigate to the dir cd C:\Users\USERNAME\Downloads\FILENAMEDIR\FILENAME and run py setup.py install
