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

[Phani Siriki]

Hi All

I am using chaos calmer build and installed python on usb. When i tried to
install python-pip, it gives me below error. However, pip is installed. But
when I tried to run it, it says command not found. Could some one help me
on this?

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)

Hi Lars

Thank you for your reply.

Yes. "python -m pip" worked.

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

-ash: python: not found

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

You are correct. There are some relocation errors, Could you give me some
pointers on how to resolve this?

Hi Lars

I am facing new problem while I try to use pip on a different router.

I have installed python and python-pip on usb. python is working fine,
but pip is not working now.

Package python-pip (1.5.6-1) is installed on usb and has the following files:

....
/mnt/usb/usr/bin/pip

It is installed in site-packages. Does it have any effect? Could you
please provide some inputs on this?

/mnt/usb/usr/bin/pip
-ash: pip: not found

I guess, the lines above show the problem: the pip executable can be found, but
its execution fails with "not found".
This is a slightly ambiguous message telling you, that either the executable
or one its linked libraries is missing. Just run "ldd /mnt/usb/usr/bin/pip" in
order to find name of the missing library. Did you adjust the LD_LIBRARY_PATH
in order to use libraries installed outside of your root filesystem?

Cheers,
Lars

Hi Lars

Yes. I have adjusted the LA_LIBRARY_PATH as below. But still pip cant be found.

***@OpenWrt:~# echo $LD_LIBRARY_PATH
/mnt/usb/lib:/mnt/usb/usr/lib

***@OpenWrt:~#
***@OpenWrt:~# ldd /mnt/usb/usr/bin/pip

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?

Cheers,
Lars

Hi Lars

Thanks for your reply.

pip has following code.

***@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')()
)
***@OpenWrt:~#

***@OpenWrt:~# ls /usr/bin/python2.7
ls: /usr/bin/python2.7: No such file or directory
***@OpenWrt:~#
***@OpenWrt:~#
***@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
