Pip已安装，但找不到命令

Question

Pip已经在我的机器上使用了多年，但是最近我无法使其正常工作。 为了解决这个问题，我跑了：

$ sudo python get-pip.py
The directory '/Users/tomeldridge/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

    Uninstalling pip-7.1.2:

Successfully installed pip-8.1.2 wheel-0.29.0

但是pip仍然不起作用：

$ pip --version
-bash: pip: command not found

我想可能是因为$PATH引起了这个问题。

当我运行`sudo bash -c'echo $ PATH'时，我得到：

/usr/sbin:/usr/bin:/sbin:/bin:usr/local/bin

这个对吗？

Answer 1

您的问题是路径中的usr/local/bin ，它必须是/usr/local/bin 。

那应该做。

您应该可以在~/.bash_profile文件中进行更改。
