推荐答案
您需要root特权
由于要安装系统级的库，因此通常会将它们放置在需要具有root用户特权才能进行写入的目录中(例如，/usr/lib下的任何内容).因此，您需要以root用户身份运行命令:
You Need Root Privileges
Since you are installing sistem-wide libraries, these usually will be placed in directories which need root privileges for writing in them (for example anything under /usr/lib). Hence you need to either run the command as root:
# pip install gittle
或者您可以使用sudo:
Or you can use sudo:
$ sudo pip install gittle
虚拟环境如何?
更有效/Python化的方法是使用虚拟环境.如果要安装特定于项目的库，则尤其如此，而其他项目很可能不需要该库.虚拟环境的另一种经典应用是在没有root特权的计算机上工作，例如在大学里.
What About Virtual Environments?
The more efficient/pythonic way to go about this would be using virtual environments. This is especially true if you are installing project-specific libraries, which will most probably not be required by other projects. Another classical application of virtual environments is when you are working on a machine on which you don't have root privileges, say at university for example.
设置虚拟环境后，如果将其放置在具有写权限的目录中，则可以运行:
Once you set up a virtual environment, if you place it in a directory on which you have writing rights, you can run:
$ pip install gittle
在这种情况下安装gittle.
