pip config set global.index-url http://mirrors.aliyun.com/pypi/simple/ # 或者直接修改 ~/.pip/pip.conf 配置文件
# 进行全局设置 pip config set global.index-url http://mirrors.aliyun.com/pypi/simple/ # 只为特定安装包 pip install --index-url http://mirrors.aliyun.com/pypi/simple/ "<pkg-name>"
通过 requirements.txt 文件，可以在其中保存需要安装的 Python 模块，然后使用 pip install -r requirements.txt 命令安装。

SyntaxError: invalid syntax
you’ll need to version lock PIP when you upgrade it to 9.0.3. This is the last stable version of PIP that is compatible with Python 2.6
我们先解决语法错误问题，使命令可用（否则执行 pip 将永远返回错误）：
yum reinstall -y python-pip pip install pip==9.0.3
在我们的场景中，我们需要安装 Supervisor 工具，由于 CentOS 6.5 已经自带，所以直接安装即可（yum install supervisor）。
由于 CentOS 6.5 没有提供 Python 2.7 版本，因此语法无法兼容，因此我们无法将 pip 升级到 9.0.3 版本之后。
也不建议强制安装 Python 2.7 版本，因为这可能会破坏 YUM 工具，或者其他软件。
如果需要使用其他版本，建议使用虚拟环境，或者可以考虑使用 Python 3.4 版本（存在于 CentOS 6.5 仓库中）。
