点子不安装鼻子包

Question

First off, let me say I'm a newbie to the Unix command line, so forgive me if anything sounds naive. I've installed pip on my machine and I'm trying to use it to install nose. I have a nose zip file in my downloads folder and I'm trying to install it into my sitepackages directory so I can begin using it for unit testing. In terminal, I typed in pip install nose and got what you see below.Any idea what's going on here? Do I need to use sudo or does the nose zip file need to be placed in another directory to be accessed by pip perhaps?...

Answer 1

您需要使用sudo pip install nose的sudo 。

Answer 2

You are trying to install nose globally without having the necessary permissions.

You can either use sudo pip install nose , or, preferably, use virtual environments ( https://virtualenv.readthedocs.org/en/latest/ ) for your development. With those, you can install and remove things without root permissions, you cannot mess up your global setup and you can use different versions of libraries within different projects you are working on.

If you try virtual environments, also take a look at virtualenvwrapper , that helps a lot in keeping them organized.
