Mac 终端上没有 python 的此类文件或目录

Question

hello.py is my first python program. It is saved on my desktop.

In the terminal I write in front of

user@AA-MacBook-Air ~ % python3 hello.py

The error is

can't open file 'hello.py': [Errno 2] No such file or directory

Kindly help me understand the problem and solve it.

Answer 1

you first need to change destination with cd

Answer 2

The error message, No such file or directory pretty much gives the explanation. Check if the file hello.py is present in the correct working directory. This can done graphically or using the ls command. If it is not present, copy the file the to the directory or navigate to the location of the file hello.py in terminal using cd .

Answer 3

In the terminal you are currently in the directory ~ . This signifies the folder /Users/<username> . Your script is on your desktop.

Type cd Desktop to change to /Users/<username>/Desktop and then run python3 hello.py .
