python中安装pip_Python 2.7中安装pip的方法及步骤

1､安装setup-tools

下载安装包，可以使用wget命令下载。下载及安装命令如下，wget https://pypi.python.org/packages/45/29/8814bf414e7cd1031e1a3c8a4169218376e284ea2553cc0822a6ea1c2d78/setuptools-36.6.0.zip#md5=74663b15117d9a2cc5295d76011e6fd1

unzip setuptools-36.6.0.zip

cd setuptools-36.6.0

python setup.py install

2､Python2安装pip

可以使用wget命令下载。下载及安装命令如下，wget https://pypi.python.org/packages/11/b6/abcb525026a4be042b486df43905d6893fb04f05aac21c32c638e939e447/pip-9.0.1.tar.gz#md5=35f01da33009719497f01a4ba69d63c9

tar -zxvf pip-9.0.1.tar.gz

cd pip-9.0.1

python setup.py install

3､创建pip软链接

如果上面执行完成，可以正常使用pip命令，也可以不执行下面命令创建软链接。

进入到/usr/local/python27/bin目录，如果上面安装没报错的话，就可以看到easy_install和pip命令，创建命令如下，rm -rf /usr/bin/easy_install* /usr/bin/pip

ln -s /usr/local/python27/bin/pip2.7 /usr/bin/pip

ln -s /usr/local/python27/bin/pip2.7 /usr/bin/pip27

ln -s /usr/local/python27/bin/pip2.7 /usr/bin/pip2.7

ln -s /usr/local/python27/bin/easy_install /usr/bin/easy_install

ln -s /usr/local/python27/bin/easy_install /usr/bin/easy_install27

ln -s /usr/local/python27/bin/easy_install /usr/bin/easy_install2.7

# 验证操作是否成功

pip --version

pip 9.0.1 from /usr/local/python27/lib/python2.7/site-packages/pip-9.0.1-py2.7.egg (python 2.7)

easy_install --version

setuptools 36.5.0 from /usr/local/python27/lib/python2.7/site-packages/setuptools-36.5.0-py2.7.egg (Python 2.7)
