Centos 6 自带的2.6版本队友有些情况总会出现各种错误，例如：
File "/usr/lib/python2.6/site-packages/pip/_internal/index.py", line 526
{str(c.version) for c in all_candidates}, ^
SyntaxError: invalid syntax
明确你的Linux版本
cat /etc/redhat-release
安装依赖：
yum groupinstall -y "Development tools" yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel
下载最新版本并编译安装
cd /tmp wget https://www.python.org/ftp/python/2.7.15/Python-2.7.15.tgz tar zxf Python-2.7.15.tgz cd Python-2.7.15 ./configure make && make install
#新版目录
ll -tr /usr/local/bin/python*
#系统自带老版本目录
ll -tr /usr/bin/python*
备份老版本命令，创建新版本软连接
mv /usr/bin/python /usr/bin/python.old rm -f /usr/bin/python-config ln -s /usr/local/bin/python /usr/bin/python && ln -s /usr/local/bin/python-config /usr/bin/python-config && ln -s /usr/local/include/python2.7/ /usr/include/python2.7
检查一下是否正确
python --version
为新版 Python 安装 setuptools
wget https://bootstrap.pypa.io/ez_setup.py -O - | python easy_install pip
然后就可以pip安装了
pip install itgeeker
