尝试从脚本执行二进制文件时，pkexec“找不到这样的文件或目录”

Question

I'm trying to execute a binary from a python script by using asyncio . I'm using the run command from here . I tried running it regularly, but I apparently don't have the permissions (even though it did work with another binary) so I do know that the file name is correct. I also saw that pkexec might need the full path so I gave it the full path just in case and I still got the same error: cannot run program./linkerd: No such file or directory

import os
import asyncio

linkerd_f = linkerd_name() # The file's name in the directory
cwd = os.getcwd()
os.chmod(linkerd_f, 755)
asyncio.run(run(
    'pkexec .' + cwd + '/' + linkerd_f))

As for how I run the script, I simply run it through python: python3.7 script.py

Your error is being generated by pkexec itself as your call syntax is incorrect.

You used os.cwd() to get the CWD but then you prepend it with a . which invalidates the full path.

Effectively the equivalent of this:

amos:/tmp$ ll simple.sh
-rwxr-xr-x 1 amos amos 73 Mar 16 11:51 simple.sh*
amos:/tmp$ pkexec .$PWD/simple.sh
Cannot run program ./tmp/simple.sh: No such file or directory
