Bash脚本在virtualenv中运行python脚本

Question

I'm creating PHP application which need to run python script. I must use virtualenv. In project catalog i've created env directory and inside created virtual env named python . In another catalog i've put script i'd like to run and this bash script:

#!/bin/bash

app="$(pwd)/../"
pythonEnv="${app}env/python/"
source ${pythonEnv}"bin/activate"
"${pythonEnv}bin/python" "${app}scripts/script.py arg1 arg2"

But when i run this script (using terminal so far) i got this error:

/var/www/project/scripts/../env/python/bin/python: can't open file '/var/www/project/scripts/../scripts/script.py arg1 arg2': [Errno 2] No such file or directory

Of course there is script.py in scripts directory and has right access permissions:

-rwxrwxr-x

What am I doing wrong?

Answer 1

Reading your error message, it appears that the interpreter thinks that the file is /var/www/project/scripts/../scripts/script.py arg1 arg2 and not simply /var/www/project/scripts/../scripts/script.py . You should separate arg1 and arg2 from the file name.

Also, I think you can just write python instead of "${pythonEnv}bin/python" once you activated your virtual environment.

Answer 2

Due to your quoting, you are trying to call "${app}scripts/script.py arg1 arg2" as the script name - which does not exist. You can change your script to fix it:

${pythonEnv}bin/python ${app}scripts/script.py arg1 arg2

Adjust your quoting as needed, but keep it specific. For example, if you need to quote your pythonEnv variable do "${pythonEnv}" .
