无法使用pip3来安装软件包

Question

嘿伙计们，我认为我的pip3刚刚遇到障碍。有人可以帮我这个。 我运行了这个命令：

pip3 install tensorflow

它将此作为输出： 此输出不仅包含tensorflow包，而且还包含我尝试使用pip3安装的任何包。

   Traceback (most recent call last):
  File "/usr/bin/pip3", line 9, in <module>
    from pip import main
  File "/home/het/.local/lib/python3.5/site-packages/pip/__init__.py", line 26, in <module>
    from pip.utils import get_installed_distributions, get_prog

    declare_namespace(pkg)
  File "/home/het/.local/lib/python3.5/site-packages/pip/_vendor/pkg_resources/__init__.py", line 2152, in declare_namespace
    _handle_ns(packageName, path_item)
  File "/home/het/.local/lib/python3.5/site-packages/pip/_vendor/pkg_resources/__init__.py", line 2092, in _handle_ns
    _rebuild_mod_path(path, packageName, module)
  File "/home/het/.local/lib/python3.5/site-packages/pip/_vendor/pkg_resources/__init__.py", line 2121, in _rebuild_mod_path
    orig_path.sort(key=position_in_sys_path)
AttributeError: '_NamespacePath' object has no attribute 'sort'

可能是什么原因 编辑：pip工作正常，但pip3不起作用

Answer 1

尝试更新pip和setuptools

pip3 install --upgrade pip setuptools

此外，最好的方法是使用virtualenv

您使用的语法错误。只需在命令提示符下尝试pip install tensorflow，一切都应该顺利进行。我尝试了我的结果并且有效。参考附图。请参阅前几行和最后几行。
