Errno2在python中没有这样的文件或目录。 无法打开.py或.csv或.tar.gz

Question

Donnas-MBP:~ donna$ cd Applications
Donnas-MBP:Applications donna$ python3 app.py
/Library/Frameworks/Python.framework/Versions/3.6/Resources/Python.app/Contents/MacOS/Python: can't open file 'app.py': [Errno 2] No such file or directory

app.py is saved in Applications. I know it's there. All of my .csv and .py files are there. I know because it was working before. But now nothing is working. I tried absolute path and that did not work. I'm using high sierra.

I tried running ls

Donnas-MBP:Applications donna$ ls
Documents   Utilities

My files were not here. This used to work fine. Not sure what happened.

Answer 1

FRom the result of ls you posted, there are no files in Applications just those two directories. Perhaps the files you seek are in those directories not Applications .
