Install pip

To install pip, securely download get-pip.py. [2]

Then run the following (which may require administrator access):

python get-pip.py

If setuptools (or distribute) is not already installed, get-pip.py will install setuptools for you. [3]

To upgrade an existing setuptools (or distribute), run pip install -U setuptools. [4]

Additionally, get-pip.py supports using the pip install options and the general options. Below are some examples:

Install from local copies of pip and setuptools:

python get-pip.py --no-index --find-links=/local/copies

Install to the user site [5]:

python get-pip.py --user

判断是否已经安装好，在命令行界面下，输入 pip --help，如果有反馈，没报错，就说明已经安装好了。
