Pyinstaller compiled binary runs from %temp% folder
I am using sys.path[0] in my script to detect the folder my script resides in. I have no issues running the executing the .py file.
I then compile the script using pyinstaller and run it, it fails. I noticed that when exe runs, the sys.path[0] changes to %temp%. Looks like exe runs from %temp% directory. However, in another place I reference sys.argv[1] which does not change.
For example, I see the following when exe runs:
sys.path[0] -> C:\Users\<username>\AppData\LocalTemp<temp folder>
sys.argv[1] -> C:pathwhereexe resides
python pyinstaller

Are you using the "One-File" mode ofPyinstaller? if so:When started it creates a temporary folder in the appropriate temp-folder location for this OS. The folder is named _MEIxxxxxx, where xxxxxx is a random number.(from the documentation)

So, what do you usesys.path[0]andsys.argv[1]for ?
– John Anderson
Nov 16 '18 at 20:21
Usingsys.argv[1]to check for the existence of CLI argument. Not usingargparsebecause there is no arg parsing required, the script just requires one argument to be passed to a function later. Forsys.path[0], the script loads external binaries that are stored in the same folder as the script, so I needed a to detect the path the script is stored in. I changed my code topath = sys.argv[0]; path = "%s\drivers" % '\'.join(path.split('\')[0:-1]). It works now.

For future reference, you can check if your app is being run in aPyinstallerbundle by checkingif getattr( sys, 'frozen', False ):. And if so, the absolute path to the bundle folder issys._MEIPASS.
