[GRASS-dev] [GRASS-user] GRASS 8.2 for Mac - wxPython problem - solved?

Wed Jun 8 10:08:08 PDT 2022

I just looked at my ~/Library folder.

I have ../GRASS/8.2/Addons but nothing is in it. My addons are all in ~/Library/GRASS/8.2/Modules. I did not move them to there manually.

I vaguely remember a bit of discussion some months back about changing where addons are stored. This may be related. If anyone remembers that discussion it would be good to relook at it.

I moved all the directories in ~/Library/GRASS/8.2/Addons into /Modules and it fired up right away...... with no error messages at all.

Hope this doesn't break something else -

Yes, no problem.

Do 7.8 and 8.0.2 open ok?

Yes, very strange.  I am able to open it with no problem in a 'clean' partition that I keep for testing.  But there is an odd prequel to the actual opening:

<Screen Shot 2022-06-08 at 9.19.03 AM.png>

where some library files seem to be missing.  The Library file structure for 8.2 is different from previous versions in that there is the addition of 'Addons' that contains most of the directories previously contained in 'Modules'.  This appears to be why the startup shell can't find the 'docs' directory.

The above is from my test partition and that's why there's no 8.0.   This probably does not affect my problem although there is one reference to the gui_user_menu.sh that might be relevant.

I replaced my grassdata directory with a new empty one and get the same 'bad magic number in 'wx' : b'\x03\xf3\r\n' ' error.

Remarkably this is not a unique problem:

https://discuss.wxpython.org/t/importerror-bad-magic-number-in-wx-b-x03-xf3-r-n/34191/14<https://urldefense.com/v3/__https://discuss.wxpython.org/t/importerror-bad-magic-number-in-wx-b-x03-xf3-r-n/34191/14__;!!IKRxdwAv5BmarQ!ap-1byJ8Fj1uktGcT4HQfHfzzBsPnTDQwyC6ZKrLo0FP2aBS_6wit5G362d4QKEfy4nAcnOnZAYqDk0-THA1YbA$>

In this case the eventual cause was the use of an illegal file name (wx.py)

This one actually makes more sense:

https://stackoverflow.com/questions/52477683/importerror-bad-magic-number-in-time-b-x03-xf3-r-n-in-django<https://urldefense.com/v3/__https://stackoverflow.com/questions/52477683/importerror-bad-magic-number-in-time-b-x03-xf3-r-n-in-django__;!!IKRxdwAv5BmarQ!ap-1byJ8Fj1uktGcT4HQfHfzzBsPnTDQwyC6ZKrLo0FP2aBS_6wit5G362d4QKEfy4nAcnOnZAYqDk0-w0OZE84$>

Since the magic number is the same, it seems that I may have some relic Python 2.7 pyc files floating around.  I've deleted all of them now (I think) but the problem remains.  So back to the drawing board......

@Nicklas - thanks for the suggestion - both calls give the same correct python3 result.

This is weird, especially because it is calling Spearfish. It opens fine on my Mac.

Have you used a GRASS 8 version previously?

Here is a guess to try.

1. Have you opened and been using Spearfish recently? If so, use an older version (preferably 8.0.2 but also 7.8 maybe) to select another location and quit cleanly. This sets the current location.

2. If you have not been using Spearfish, try moving it out of your GRASS database temporarily.

A guess is that this is a problem with the new GRASS 8 data catalog. I ran into an obscure problem when it was first started in that the data catalog would only partly open if there was a file in a GRASS mapset with the "@" character in its name. I had this for a couple of files because of an old way that 3D rasters used to be created 10+ years ago. You may have some other such obscure issue.

My guess is assuming that the error message is somewhat bogus. The 8.2 app does include wxPython and of the proper version. And it should not be looking for wxPython anyplace else on your system outside of the app.

On start up I get the following notification in the terminal - this is followed by my attempt to open wxGUI manually:

You can still use GRASS GIS modules in the command line or in Python.

Not sure if this is a packaging or dev issue.  If the latter please let me know and I'll report it.....

Thanks for the info. I thought I'd fixed that (I have to do it each time). Please try again. Hopefully fixed this time.

There seems to be a problem with the download link - Google says I don't have access for that page.  The links for the earlier versions of GRASS work fine..... also for the configuration info of the new one.

OSX 11.6.6
