Cannot import pyo on fresh install

[xorap]

I'm just beginning to grasp python, but am at the point where I've installed pyo through pip into python 3.9.10.
(same for 3.8.9)
However, by the looks of my error, there is a missing file _pyo in the .lib folder.

I run only 'import pyo' and get the following error:

Traceback (most recent call last):
File "<tmp 1>", line 1, in
import pyo
File "C:\Users\Christopher\AppData\Roaming\Python\Python39\site-packages\pyo_init_.py", line 27, in

from .._pyo import *
ImportError: DLL load failed while importing _pyo: The specified module could not be found.

Same error if I copy the first example script from your setup guide. http://ajaxsoundstudio.com/pyodoc/gettingstarted.html

I tried looking for the '..pyo\lib_pyo.py' in github (https://github.com/belangeo/pyo/tree/master/pyo/lib) and its not there, so maybe there isn't supposed to be one, but at this point I'm at a loss and really don't want to give up this project I haven't even started.

-I've set environment variables to my python modules & python scripts.
-I've set pythonPath to the correct directory in my IDE (I'm using Pyzo).
-I've reinstalled everything a few times.

Hi,

A few things:

1. The file you are looking for should be in site-packages/pyo directory, named something like _pyo...pyd. If it's not there, something went wron with the installation.
2. Can you try to import pyo in a Command Prompt (easier to diagnose when removing the IDE layer):

py -3.9
>>> import pyo

Hi! Thank you for the rapid response!
Below I've pasted my CMD with a fresh installation of pyo.

I'm dumb and realize I was not running my cmd as an admin in that last example.

I decided to try a reisnstall of pyo after upgrading pip aswell.

Hello again,
I decided to follow the build routine to install from the source code (https://github.com/belangeo/pyo/blob/master/scripts/win/windows-10-64bit-build-routine.txt).
I managed up to the final step, after downloading the sources through git. I ran py -3.9 setup.py install --use-double
It ran several lines of code before coming to this error:

Command line error D8021 : invalid numeric argument '/Wno-strict-prototypes'
error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\Enterprise\\VC\\Tools\\MSVC\\14.29.30133\\bin\\HostX86\\x64\\cl.exe' failed with exit code 2

And from there I still attempted to import pyo in python and got the exact same error.... I think I'm getting somewhere, I think it might have to do with step 10, I verbatim copy pasted PythonXX/vcruntime140.dll from ./Python39/ into ./Python39/libs/
or perhaps it was step 12. I just used my IDE to make a fresh file:

[build]
compiler = mingw32

I was successful through every other step of the build routine.
I really don't want to give up on this.

[belangeo]

Step 12, the file must have the exact name and path...

Honestly, I don't think trying to build from scratch on Windows is the way to go, it's a much more complicated setup than on unix systems. Installation from pip should work flawlessly. I'd go with:

1. Remove everything pyo related on your computer (in the site-packages directory of all installed python distributions, check both system wide and user site-packages).
2. For the desired python installation (downloaded from python.com right?), 3.9 here:

• Open a command prompt:
• Just for sanity:
  py -3.9 -m pip uninstall pyo
• Then:
  py -3.9 -m pip install --user pyo wxPython

wxPython is not mandatory, but pyo uses it for GUI stuff.

If installation went well, you can try it:

>py -3.9
>>> import pyo

If there were errors in the pip installation, post the log messages here...

[xorap]

Okay

1. I did py -x.x -m pip uninstall pyo for each version of python I had. Also wxPython.
2. I fully uninstalled every version of python, then manually deleted every remnant from C:\Program Files\ & from .\Appdata\Roaming\Python
3. Reinstalled from a freshly downloaded (64 bit) installer from python.org (same as before). Default file paths.
4. CMD

No luck, same error. idk
I tried uninstalling my IDE, even though I wasn't using it. Repeated the whole above process, no luck.

Do you get anything more if you do:

py -X dev
>>> import pyo

[xorap]

C:\>py -3.9 dev
C:\Users\Christopher\AppData\Local\Programs\Python\Python39\python.exe: can't open file 'C:\dev': [Errno 2] No such file or directory

I'm not familiar with using dev

[belangeo]

The exact command is:

py -3.9 -X dev

-X is the flag, and dev is the value!

From the doc:

-X dev: enable Python Development Mode, introducing additional runtime checks that are too expensive to be enabled by default.

Tragic

[belangeo]

The first time, you installed pyo as admin, did you also pip uninstall as admin?

What is the content of the PATH environment variable?

[xorap]

Yep all as admin heres an imgur cap of my path variables:
https://imgur.com/a/UPzYw3n

[xorap]

Do you think it could be my network?

[xorap]

I tried a fresh install of pyo today and I think it worked! No error!! I can finally start!
