Why does Virtual Studio code keep failing to fine file or directory in python

I run my code in Pythons build in IDLE Shell and it will run no problem. But once it is in virtual studio it then throws this error code.
I have gone into my Python Extension settings and have checked the 'Execute In File Dir' like multiple other posts and fixes say, but it does not seem to resolve my issue.

Failed to execute script 'App-Name.py' due to unhandled exception: [Errno 2] No such file or directory

I made a python app using pygame and pygame-gui library. I've been getting this error when I try to run the python app that I've converted into an exe file. I used this command: pyinstaller App-Name.py --hidden-import=data.jsonfile --onefile --noconsole for creating the executable. And when I try to run it, it gives me this error:
Failed to execute script 'App-Name.py' due to unhandled exception: [Errno 2] No such file or directory: 'C:\Users\Acer\AppData\Local\Temp\_MEI164642\data\jsonfile\theme-1.json'

I've tried looking for the answer anywhere but nothing works so far. Any help would be appreciated!

try reinstalling pyinstaller or try other modules such as cx_freeze

djangocms: AttributeError: 'FileNotFoundError' object has no attribute 'cmd'

I am trying to install Django CMS on windows. I am using following steps.
C:\Python34\Scripts\pip install djangocms-installer
E:\Projects\example>C:\Python34\Scripts\djangocms -p mysite mysite
But throws following error:

AttributeError: 'FileNotFoundError' object has no attribute 'cmd'
I have searched on it but can't get any solution.

The root cause is this line:
output = subprocess.check_output(['pip'] + args, stderr=subprocess.STDOUT)
so put the PATH on the pip executable location and it should work:
set PATH=%PATH%;C:\Python34\Scripts
At first glance, sounds that the package is not very adapted to Windows environment... The double exception is not very nice, and calling pip without any path can be a problem.

Shelve Module Not Working

After I reinstalled Python to move it from an AppData folder to Program Files, it looks like the shelve module is no longer working and I receive the error below when I call upon shelve.open().
Please help!

>>> myShelf = shelve.open('data')

>>>

The error "FileNotFoundError: [Errno 2] No such file or directory: 'data.dat'" shows you, it can not find the data.dat, please check the file location.

I had this problem using Windows 10. I solved the issue by changing the working directory to a folder under my profile.
os.chdir('C:\\Users\\Nat\\Documents\\Python\\Project 1')
I presume I didn't have permission to write a file 'Program Files'.
