No APPDATA environment variable in Linux: expected str, bytes or os.PathLike object, not NoneType

Trying to run

from pandasgui import show

on Ubuntu Linux fails with:

APPDATA is a Windows-specific environment variable.

As a workaround one can set the variable to a dummy value:

export APPDATA=

In general it would be nice if “adding to the start menu” was wrapped in some operating system detection, because it only makes sense on Windows anyway.

Where to execute "export APPDATA=" ? I tried on Linux Terminal, but the error still persist

[CarelKattriggerise]

I just commended out the line #SHORTCUT_PATH = os.path.join(os.getenv('APPDATA'), 'Microsoft/Windows/Start Menu/Programs/PandasGUI.lnk', ) and that worked for me

Where did you comment out the line?

having the same issue on my mac; can not find a solution

I got same error on my mac.

The PyPI version may be old. Trying pip install git+https://github.com/adamerose/pandasgui.git solved the issue for me.

Where to execute "export APPDATA=" ? I tried on Linux Terminal, but the error still persist

I put the following in my script:

import os os.environ['APPDATA'] = ""

[Buedenbender]

Same issue for me on a debian based distribution. If possible I think it could be beneficial for the package to tackle this issue. Some possible new users might become disheartend by the error and dish this great package without ever using it.

Installing directly from git is sadly not always possible in an enterprise setting. I circumvented the problem by adding the dummy export to my .bashrc file, which is execute on the start of a new terminal. If you want to follow along:

1. Use a text editor to open your .bashrc file (e.g., nano, vim, whatever)

nano ~/.bashrc

2. Add export statement for the dummy enviroment variable to the end of the file

export APPDATA=

3. Save and exit the text editor

This fixed the error. That being said, it does not work well in devcontainer at all, my next barrier would be

ImportError: this platform is not supported: ('failed to acquire X connection: Bad display name ""', DisplayNameError(''))

Try one of the following resolutions:

 * Please make sure that you have an X server running, and that the DISPLAY environment variable is set correctly

To solve the issue I did :

git clone https://github.com/adamerose/PandasGUI.git
cd PandasGUI
nano pandasgui/constants.py

Commented the 3 last line :

#SHORTCUT_PATH = os.path.join(os.getenv('APPDATA'), 'Microsoft/Windows/Start Menu/Programs/PandasGUI.lnk', )
#PY_INTERPRETTER_PATH = os.path.join(os.path.dirname(sys.executable), 'python.exe')
#PYW_INTERPRETTER_PATH = os.path.join(os.path.dirname(sys.executable), 'pythonw.exe')

saved the file and :

pip install .

And it's now working (Ubuntu 22.04, python3.10)
