Python pip doesn't work on Linux mint

问题:

I have had this error for a year now and still can't find a solution. I am using Linux Mint 17.3 Every time I try to install something using pip, I get a bunch of exceptions.

$ pip install -U scikit-learns Exception: Traceback (most recent call last):   File "/usr/local/lib/python2.7/dist-packages/pip-9.0.1-py2.7.egg/pip/basecommand.py", line 215, in main     status = self.run(options, args)   File "/usr/local/lib/python2.7/dist-packages/pip-9.0.1-py2.7.egg/pip/commands/install.py", line 272, in run     with self._build_session(options) as session:   File "/usr/local/lib/python2.7/dist-packages/pip-9.0.1-py2.7.egg/pip/basecommand.py", line 72, in _build_session     insecure_hosts=options.trusted_hosts,   File "/usr/local/lib/python2.7/dist-packages/pip-9.0.1-py2.7.egg/pip/download.py", line 329, in __init__     self.headers["User-Agent"] = user_agent()   File "/usr/local/lib/python2.7/dist-packages/pip-9.0.1-py2.7.egg/pip/download.py", line 93, in user_agent     from pip._vendor import distro   File "/usr/local/lib/python2.7/dist-packages/pip-9.0.1-py2.7.egg/pip/_vendor/distro.py", line 1050, in <module>     _distro = LinuxDistribution()   File "/usr/local/lib/python2.7/dist-packages/pip-9.0.1-py2.7.egg/pip/_vendor/distro.py", line 594, in __init__     if include_lsb else {}   File "/usr/local/lib/python2.7/dist-packages/pip-9.0.1-py2.7.egg/pip/_vendor/distro.py", line 933, in _get_lsb_release_info     raise subprocess.CalledProcessError(code, cmd, stdout) CalledProcessError: Command 'lsb_release -a' returned non-zero exit status 1 Traceback (most recent call last):   File "/usr/local/bin/pip", line 9, in <module>     load_entry_point('pip==9.0.1', 'console_scripts', 'pip')()   File "/usr/local/lib/python2.7/dist-packages/pip-9.0.1-py2.7.egg/pip/__init__.py", line 233, in main     return command.main(cmd_args)   File "/usr/local/lib/python2.7/dist-packages/pip-9.0.1-py2.7.egg/pip/basecommand.py", line 251, in main     timeout=min(5, options.timeout)) as session:   File "/usr/local/lib/python2.7/dist-packages/pip-9.0.1-py2.7.egg/pip/basecommand.py", line 72, in _build_session     insecure_hosts=options.trusted_hosts,   File "/usr/local/lib/python2.7/dist-packages/pip-9.0.1-py2.7.egg/pip/download.py", line 329, in __init__     self.headers["User-Agent"] = user_agent()   File "/usr/local/lib/python2.7/dist-packages/pip-9.0.1-py2.7.egg/pip/download.py", line 93, in user_agent     from pip._vendor import distro   File "/usr/local/lib/python2.7/dist-packages/pip-9.0.1-py2.7.egg/pip/_vendor/distro.py", line 1050, in <module>     _distro = LinuxDistribution()   File "/usr/local/lib/python2.7/dist-packages/pip-9.0.1-py2.7.egg/pip/_vendor/distro.py", line 594, in __init__     if include_lsb else {}   File "/usr/local/lib/python2.7/dist-packages/pip-9.0.1-py2.7.egg/pip/_vendor/distro.py", line 933, in _get_lsb_release_info     raise subprocess.CalledProcessError(code, cmd, stdout) subprocess.CalledProcessError: Command 'lsb_release -a' returned non-zero exit status 1 

The "Command 'lsb_release -a' returned non-zero exit status 1" always popped up. I have installed multiple versions of python and tried deleting them manually and it still comes up with the same error.

If you can't help me solve this error, how can I uninstall all python files?

回答1:

When I update Python and pip，I had the problem like this your can run lsb_release, if your run shell: #lsb_release

It work like:

Traceback (most recent call last): File "/usr/bin/lsb_release", line 28, in import lsb_release ImportError: No module named 'lsb_release'

You can change file (/usr/bin/lsb_release) so the shebang changes from:

#! /usr/bin/python -Es 

to:

#! /usr/bin/python2 -Es 

where you specify the path /usr/bin/python2 to the old Python binary.
