Hello,
�
I have subscribed to the Python list.
The user name (which was optional) I entered as hsb3852, not my real name.
Does this matter?
�
My question is below…

Best regards,

Subject: Issues with pip in Python 3.8.3
�
Hello,
�
I’m quite new to Python (but not new to programming), and I’ve encountered
problems with pip which I have been unable to solve.
�
When I tried to update pip using “python.exe -m pip install --upgrade pip” (I
tried to install another package -unsuccessfully, which informed me there was a
new version of pip), which failed with the following error:
�
ERROR: Exception:

ValueError: Unable to find resource t64.exe in package pip._vendor.distlib
WARNING: You are using pip version 20.2.2; however, version 20.2.3 is available.
You should consider upgrading via the 'C:\Program Files\Python38\python.exe -m
pip install --upgrade pip' command.
�
C:\Program Files\Python38>
�
I checked that the file t64.exe does exist in the location (path) listed
(C:\Users\user\AppData\Roaming\Python\Python38\site-packages\pip\_vendor\distlib\scripts).
This path is included in the PATH environment variable.
�
Why is this upgrade failing? How do I fix it?
�
I get this same error when I try to install other packages too.
�
The package I tried to install was numPy.
�
I also need to install cv2 and OpenCV, but my searches for them in PyPA
returned dozens, if not hundreds of results. Can you perhaps indicate which
versions I need to install on my Windows 10 PC?
�
Please help as soon as possible by return email.
�
Many thanks!
Hylton
