pip3未安装软件包

Question

我在终端输入以下行：

pip3 install numpy 

这给了我：

    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)
  File "/usr/local/lib/python3.5/dist-packages/pip-9.0.1-py3.5.egg/pip/basecommand.py", line 251, in main
    timeout=min(5, options.timeout)) as session:
  File "/usr/local/lib/python3.5/dist-packages/pip-9.0.1-py3.5.egg/pip/basecommand.py", line 72, in _build_session

  File "/usr/local/lib/python3.5/dist-packages/pip-9.0.1-py3.5.egg/pip/download.py", line 329, in __init__
    self.headers["User-Agent"] = user_agent()
  File "/usr/local/lib/python3.5/dist-packages/pip-9.0.1-py3.5.egg/pip/download.py", line 93, in user_agent
    from pip._vendor import distro
  File "/usr/local/lib/python3.5/dist-packages/pip-9.0.1-py3.5.egg/pip/_vendor/distro.py", line 1050, in <module>
    _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

我认为这是一个路径问题，但我不确定。

这是pip提供的distro软件包中的错误 。 该错误已解决，但是最新版本的pip使用了非常老版本的distro ，但未应用此错误修复程序。

现在，您只需尝试使可执行文件在路径中可用。
