折腾：
【已解决】升级CentOS中的supervisor到最新版本
期间，已经卸载了（yum安装的）旧版本的supervisor后，去用官网：
Installing — Supervisor 3.3.4 documentation
“* Using easy_install, which is a feature of setuptools. This is the preferred method of installation.”
推荐的easy_install去安装，希望是最新版本的supervisor
对于easy_install，注意到此处CentOS服务器中是Python3.4版本的：

先不管了，直接用此处的python3.4的easy_install去安装
安装之前，先去找找，如何easy_install查找supervisor的版本
easy_install search version

好像没有search

PyPI – the Python Package Index · PyPI
https://pypi.org/search/?q=supervisor
是：
supervisor 3.3.4
3.3.4 (2018-02-15)
所以就可以去安装了。

然后是不支持python3
-》看来前面注意到 ，此处easy_install是python3，还是有影响的。
看来只能换用pip，且是python2的pip去安装了
<code>[root@xx-general-01 robotDemo]# ll /usr/bin/pip* -rwxr-xr-x 1 root root 216 Apr 24 11:05 /usr/bin/pip -rwxr-xr-x 1 root root 216 Apr 24 11:05 /usr/bin/pip2 -rwxr-xr-x 1 root root 216 Apr 24 11:05 /usr/bin/pip2.7 -rwxr-xr-x 1 root root 216 Apr 24 11:03 /usr/bin/pip3.4 [root@xx-general-01 robotDemo]# pip --version pip 10.0.1 from /usr/lib/python2.7/site-packages/pip (python 2.7) </code>
然后去安装
然后也是，pip中先去看看，能否支持search，查看到要安装的supevisor的版本是多少

【总结】
此处的CentOS中，（不知何故）easy_install是python 3.4的，而由于supervisor暂时不支持Python3，所以去安装会失败，提示不支持。
此处只能换用python 2的pip去安装才可以。
<code>pip install supervisor </code>
安装完毕后，看看版本：
<code>pip show supervisor </code>
