Re: [OpenWrt-Users] Pip command found error even though pip is installed

[Phani Siriki]

Hi Lars

Thanks for your reply.

pip has following code.

root@OpenWrt:~# cat /mnt/usb/usr/bin/pip
#!/usr/bin/python2.7
# EASY-INSTALL-ENTRY-SCRIPT: 'pip==1.5.6','console_scripts','pip'
__requires__ = 'pip==1.5.6'
import sys
from pkg_resources import load_entry_point

if __name__ == '__main__':
sys.exit(
load_entry_point('pip==1.5.6', 'console_scripts', 'pip')()
)
root@OpenWrt:~#

root@OpenWrt:~# ls /usr/bin/python2.7
ls: /usr/bin/python2.7: No such file or directory
root@OpenWrt:~#
root@OpenWrt:~#
root@OpenWrt:~# which python2.7
/mnt/usb/usr/bin/python2.7

I will try to use micro python and see if it works for me.

Best Regards
Phani

another possible cause for the above error message could be a wrong shebang
(the first line in a script indicating its interpreter).
Usually this would expose a different error message - but maybe these
messages are simplified in busybox.

If the shebang is fine, you will need to find another reason, why this file
could be non-executable.

btw.: if you really need a full Python environment (incl. third-party modules),
then maybe an embedded environment like OpenWrt could turn out to complicate
this task a bit too much. Could micropython be an option instead? Or a
distribution that is not targeted at embedded devices?

I guess, this means that one of the libraries that the python binary is linked
against, is missing.
Maybe run "ldd /usr/bin/python" and check if all referenced libraries exist.

Hi Lars

I am now facing problem with python on a different router. I have installed
python on USB stick and I could not execute it.

root@Mesh-30:~# opkg files python
Package python (2.7.9-6) is installed on usb and has the following files:
root@Mesh-30:~#
root@Mesh-30:~# which python
/usr/bin/python
root@Mesh-30:~# ls -l /usr/bin/python

root@Mesh-30:~# python
python python2python2.7

root@Mesh-30:~# python
-ash: python: not found

Tab autocompletion works, however it says command not found. Could you
please suggest if you have any idea on this?

Best Regards
Phani

did you take a look at the list of files belonging to the "python-pip"
package?

 opkg files python-pip

I could imagine, that the package contains only the python module - and
maybe not a script in /usr/bin.

Maybe "python -m pip ..." works?
(just wild guessing)
