Python: OSError: [Errno 2] No such file or directory on subprocess.Popen

Question

I have added the path to mytool in .bashrc and I could run mytool --help from any path in bash shell. However when when I run the following snippet, I get :

File "/usr/lib/python2.7/subprocess.py", line 1249, in _execute_child raise child_exception OSError: [Errno 2] No such file or directory

import subprocess

command_array = ['mytool', '--help']

p = subprocess.Popen(command_array,
                     stderr=subprocess.STDOUT, stdout=subprocess.PIPE,
                    )

for line in iter(p.stdout.readline, b''):
        print(line)
p.stdout.close()

How can I resolve this?

EDIT: When I run the python file from terminal (bash), it works fine. But when I run from PyCharm (debugger) or other shells it is giving the above error.

How do I change my script so that it runs 'mytool' in bash when I run the script from other shells? I need the environment added in .bashrc

Solution

Add this print to your file:

import os
print os.environ['PATH']

Compare the outputs after running the script from IDE and terminal.
You should observe that the IDE's PATH does not include the mytool's directory.

The path that is printed doesn't have the paths added to .bashrc. How do I change my script so that it runs 'mytool' in bash when I run the script from other shells?

Try one of two (or both): 1) command_array = ['/path/to/mytool', '--help'] 2) Update the PATH environment variable in your IDE (howTo)
