Question

When I try to install pyinstaller in windows machine through pip gives me the following error.

What I tried:

Error:

Installing collected packages: pyinstaller

  WARNING: Failed to write executable - trying to use .deleteme logic

ERROR: Could not install packages due to an OSError: [WinError 2] The 
system cannot find the file specified: 'C:\\...\\Python310\\Scripts\\pyi-archive_viewer.exe' ->

Answer 1

I had a similar problem " Requirement already satisfied " with the Pillow module. I saw it in IDE, but it was broken. So I deleted the package folder in C:\Python310\Lib\site-packages and reinstalled it. You could try to do the same.

Answer 2

I had the same issue. I solved it by uninstallation of partially installed pyinstaller. Then I installed it as Administrator.
