Unable to run PyInstaller - “Please install PyWin32 or pywin32-ctypes”

问题

I'm using Python 3.7 32-bit on Windows 10 64-bit. Python was installed from the executable file on the Python website and NOT Anaconda package. When I run pyinstaller from the command prompt, it returns an error: Error Message I've already installed pypiwin32, pywin32 and win32ctypes. But still have the error.

I tried running pyinstaller from Windows CMD, Pycharm, and a virtual environment, all with the necessary libraries installed, but I'm unable to make it work.

I've googled a lot on this issue but unable to find an answer. Can anyone please help?

回答1:

Open python (tested using Python 3.7.4) and check if the modules can be found from the environment without intervening:

python.exe
>>>import pywintypes
>>>import win32api

If successful, the fix is simple. Find the file compat.py inside the PyInstaller folder. and edit the following two lines.

Replace:

    from win32ctypes.pywin32 import pywintypes
    from win32ctypes.pywin32 import win32api

with

    import pywintypes
    import win32api

I'm running Python 3.6 on a 32-bit Windows 10 64-bit machine. Using the latest stable version from "pip install pyinstaller" I ran into the same error as you.

The fastest way to fix this is to run the following from cmd:

pip uninstall pyinstaller

Then run the following in cmd:

pip install https://github.com/pyinstaller/pyinstaller/tarball/develop

This gives you the version currently in development where they have fixed the issue.
