Python subprocess throws [Errno 2] No such file or directory, error generated only when it on a remote host

Question

I'm running python 2.6. I'm getting the subprocess throws [Errno 2] No such file or directory only when I run the script via ssh.

For example, if I run the script manually on the machine, there are no errors, but if I do ssh hostname script.py --host hostname it generates the error and tells me that File "/usr/lib64/python2.6/subprocess.py is missing, but that's not true as both servers have that file.

I've written the subprocess call like this:

p4 = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)

The command just contains a list.

Any ideas why it works locally, but not remotely?

Answer 1

The solution for this was to simply have the command set to the absolute path, for example, instead of mke2fs, I needed /sbin/mke2fs.
