python安装setuptools步骤详解

作者：袖梨 2022-11-14

Python中当需要安装第三方python包时，可能会用到easy_install命令。easy_install是由PEAK(Python Enterprise Application Kit)开发的setuptools包里带的一个命令，所以使用easy_install实际上是在调用setuptools来完成安装模块的工作。

为了方便后续安装各种第三方python包，需要先安装setuptools。

安装setuptools的话，下面一条简单的命令就可以搞定，脚本会自动为你安装适合你系统的对应版本。

代码如下	复制代码
# wget https://bootstrap.pypa.io/ez_setup.py -O - \| python

大部分情况下，上面的命令都可以完成setuptools的安装，不过我在CentOS系统中安装setuptools的时候，貌似没那么顺利呢，所以我的解决办法如下：

代码如下

复制代码

# wget --no-check-certificate https://bootstrap.pypa.io/ez_setup.py -O - | python

自动安装脚本需要去下载一个文件，可是下载不下来，卡在Downloading这里了，只好改成手动方式下载了

代码如下

复制代码

# wget https://pypi.python.org/packages/source/s/setuptools/setuptools-5.7.zip --no-check-certificate

下面把自动安装脚本也下载下来，让这个脚本替我们去安装

代码如下

复制代码

最后完成安装
