Problem Description

Sorry for potentially asking a stupid question: I installed spyder(5.5.4) via standalone Windows installer which has come with the pywin32 package. But when I run import win32gui
, I get:ModuleNotFoundError: No module named 'win32gui'

What steps reproduce the problem?

1. pip show win32gui
2. import win32gui

What is the expected output? What do you see instead?

I expect to see import win32gui smoothly.

Hey @GeolChao, thanks for reporting. I'm really not sure what's happening but we'll take a look at it.

@dalthviz, could you take a look at what's happening here? Thanks!

Note: Maybe related with mhammond/pywin32#1730 (comment)

[ccordoba12]

Thanks for checking @dalthviz. An additional question for you: are you able to run import win32gui in our installer? Or do you get the same error as @GeolChao?

[dalthviz]

I get the same ModuleNotFoundError for win32gui but when I was checking this I also tried to import win32api and I got an ImportError:

Which lead me to post the Note above

[ccordoba12]

Ok, and what happens with our Spyder 6 beta2 installer? I don't know if pywin32 is available there, but if it is, the problem shouldn't be present because our new installers use Conda packages.

Using Spyder 6.0.0b2 installer on Windows I'm unable to reproduce this:

Ok, that's great!

@GeolChao, given that the error is fixed in our new installers, I'm going to close this issue as solved for Spyder 6. That version will be released in three weeks or so, so you won't need to wait too long to get it.
