Python on Android subprocess: /bin/sh: ls: not found

Question

As I'm running an old Python version on android which gives incorrect file sizes for files > 4 GB I tried writing a workaround to get the correct sizes, code:

def getsize_workaround( filename ):
import subprocess as s
output = s.Popen("ls -l " + filename, shell=True, executable="/system/bin/sh", stdout=s.PIPE).communicate()[0]
size = long(re.split(r'\s+', output)[3])
return size

This works well when I try to call it using a simple python script:

print(getsize_workaround(path))

However, when I try to use it in my NZBGet VideoSort script it can't find ls and pops this error at: output = s.Popen("ls -l " + filename, shell=True, executable="/system/bin/sh", stdout=s.PIPE).communicate()[0] -> : /bin/sh: ls: not found. (function is called at line 824, see dropbox link below).

Haven't got a clue why it can't find ls anymore, anyone help is much appreciated. You can find the VideoSort script here: https://db.tt/oM3U5gZR .

Answer 1

PATH variable didn't include the correct directories when run from NZBGet. Fixed by setting os.environ['PATH'] manually. Thanks to abernert for the tip.

Answer 2

还尝试在 bash 脚本中为要使用的 python 版本添加别名

alias python=<python version you want to use>
