PIP
On Windows pip may not be installed globally, so add to the PATH:
- C:\Users\jbloggs\AppData\Roaming\Python\Python313\Scripts
On Windows, start pip with:
py -m pip

Python Compilation
dnf groupinstall 'Development Tools' dnf install python3-devel libffi-devel wget https://www.python.org/ftp/python/3.12.2/Python-3.12.2.tar.xz tar xvf Python-3.12.2.tar.xz
./configure --enable-shared --enable-optimizations --with-ensurepip=install make sudo make altinstall
Altinstall does not execute bininstall and maninstall, so good for not overwriting system python. Test resultant binary:
/usr/local/bin/python3.12 --version
If you want somewhere else than /usr/local, add --prefix=/opt or similarto configure. Optionally:
make test
Virtual Environments
Create a virtual environment:
python -m venv py-env/demo
Activate a virtual environment on Windows:
py-env\demo\Scripts\activate
or Linux:
. py-env/demo/bin/activate
Install within a venv:
pip install --upgrade pip python -m pip install pyinstaller python -m pip install requests
Optionally, force a specific version, such as:
python -m pip install requests==2.30.0
Ensure shared libraries are accessible, eg:
export LD_LIBRARY_PATH=/usr/local/lib
Deactivate an env:
deactivate
Python Installer
pip install pyinstaller
Add C:\Users\<user>\AppData\Roaming\Python\Python312\Scripts to PATH:
pyinstaller --onefile file.py
and the resultant executable will be in the dist directory.
