Python ImportError: No module named wx

Question

Im sorry to ask this question again. I have searched and found endles repeats of it both on stackoverflow and also on general google search. Unfortunatly I just cant get my system sorted.

I have the following:

C:\Python27\Lib\site-packages\wx-2.8-msw-unicode

this folder contains the wx folder and also wx & wxPython folders which each contain the _init_.py files

When I import wx I get the error message "no module named wx"

What do I need to do in order to get Python to find the relevant files to allow me to "import wx" succesfully

Solution 1

Ubuntu:

sudo apt-get install python-wxtools

Solution 2

For Windows and MacOS, Simply install it with pip

pip install -U wxPython

Reference: Official site

Solution 3

Windows:

1. Go to C:\Python27\Lib\site-packages\ find the folder wx-<version>-msw or similar

2. Move the wx from the above folder to C:\Python27\Lib\site-packages\

Solution 4

I had the same error today but I tried something and surprisingly it worked. In the site packages folder there will be a file named wx.pth. Open it using notepad and its contents would be like "wx-2.8-msw-unicode"

It is basically the name of the folder containing wxpython. Delete this using Ctrl + A and copy the name of the folder from the site packages and paste it here even if it is the same.

Sounds weird but maybe the original file contained a hidden character...

Solution 5

I had the same problem for a PyMOL plugin that required the wx module, though I installed wxpython by downloading its package from here (Unofficial Windows Binaries for Python Extension Packages) and installing it with the command:

pip install .\wxPython-3.0.2.0-cp27-none-win_amd64.whl

For some reason it gave me that error, for which I uninstalled it with:

pip uninstall wxPython

and then I downloaded it from here (wxPython 4.0.0a1) and reinstalled:

pip install .\wxPython-4.0.0a1-cp27-cp27m-win_amd64.whl

The error at this point has not been presented anymore.

please, don't do that, the name is correct. If you installation has been done properly there should be a file wx.pth in site-packages pointing to that folder name.

Hi....I have checked the site-packages folder and I do have the wx.pth file present....and it contains the follwoing single line wx-2.8-msw-unicode any suggestions for sorting this would be really appreciated !

he uses windows, not ubuntu/debian

This failed with compile errors for me, using Python 2.7.

[philshem]

This worked for me after I installed wx from Unofficial Windows Binaries for Python Extension Packages

[philshem]

If the pip installation fails, you should install the binary from lfd.uci.edu/~gohlke/pythonlibs

[philshem]

FYI - this installation requires windows admin rights

The fact OP has in the question C:\Python27\Lib\site-packages\wx-2.8-msw-unicode means this answer will be rather less than useful.

[sijo0703]

This command worked for me:: pip install wxPython

[Giuseppe Urso]

Yes but that's because python 2.7 is default on your system, try pip3

for linux too, this is the best way

As per the site, for linux distro dependent, example: pip install -U \ -f extras.wxpython.org/wxPython4/extras/linux/gtk3/ubuntu-16.04 \ wxPython
