pip3未安装软件包

Question

I enter the following line into terminal:

pip3 install numpy 

this gives me:

    Traceback (most recent call last):
  File "/usr/local/bin/pip3", line 9, in <module>
    load_entry_point('pip==9.0.1', 'console_scripts', 'pip3')()
  File "/usr/local/lib/python3.5/dist-packages/pip-9.0.1-py3.5.egg/pip/__init__.py", line 233, in main
    return command.main(cmd_args)

    timeout=min(5, options.timeout)) as session:

    _distro = LinuxDistribution()
  File "/usr/local/lib/python3.5/dist-packages/pip-9.0.1-py3.5.egg/pip/_vendor/distro.py", line 594, in __init__
    if include_lsb else {}
  File "/usr/local/lib/python3.5/dist-packages/pip-9.0.1-py3.5.egg/pip/_vendor/distro.py", line 931, in _get_lsb_release_info
    raise subprocess.CalledProcessError(code, cmd, stdout, stderr)
subprocess.CalledProcessError: Command 'lsb_release -a' returned non-zero exit status 1

Im thinking its a path issue but im not really sure.

Answer 1

This is a bug with the distro package vendored by pip. The bug has been solved but the latest version of pip uses and very old version of distro which doesn't have this bug fix applied.

For now, you can simply try to make the executable available in the path.
