It appears that pip is unable to connect to PyPI (where pip downloads Python packages from). Generally, you should ensure that:

• You have a working internet connection and pip is allowed to connect to external websites.

• pip is updated (pip install -U pip).

There may also (theoretically) be some issue with the certificates associated with pip/Python.

Note that you can manually download Python packages (often bundled as .whl files or tar.gz archives) and use pip to install them locally (e.g. pip install pyinstaller-4.3.tar.gz).

Be aware, however, that the most recent versions of PyInstaller rely on a number of additional Python packages. These currently appear to include:

• altgraph
• future
• importlib-metadata
• pefile
• pyinstaller-hooks-contrib
• pywin32-ctypes
• setuptools
• typing-extensions
• zipp
