Question

Python Version=2.7, 3.4 所以我正在尝试更新pip，因为我在终端中收到以下消息。您正在使用pip版本7.0.3，但版本7.1.2可用。您应该考虑通过'pip install --upgrade pip'命令进行升级。

和此。

Collecting pip
Using cached pip-7.1.2-py2.py3-none-any.whl 
Installing collected packages: pip
Found existing installation: pip 7.0.3
Uninstalling pip-7.0.3:

然后我收到错误消息

如何解决此错误？

Answer 1

安装需要您不具备的文件权限。以sudo（sudo pip install ...）或以root用户身份运行。您将需要root密码。

unix标准文件系统层次结构是普通用户（甚至是管理员）对其homedir之外的大多数地方没有写权限。改变＆＃34;全球＆＃34;您需要具有更高权限的层次结构的路径。 root通常是高权限用户。通过在sudo前面添加命令来运行命令意味着将其作为另一个用户运行并且通常具有root权限，然后它可以写入pip尝试安装的/ Library这样的地方。
