Python安装lz4-0.10.1遇到的坑

因为项目的需求，要 lz4.0.10.1 的，因为本机已经有一个 1.1.0 版本的，所以必须先卸掉，然后我差点没疯了（手动微笑）

sudo pip uninstall lz4

准备愉快地装上 0.10.1

又是 too old ？？这样真的很迷。。赶紧谷歌了下，尝试了好几次，还是这个坑爹结果。

突然发现一个博文提到一个很神奇的语句， 不管了先试下：

抱着一些幻想，再装下我的 lz4，结果很明显，幻想就是幻想，还是报的神奇的too old...
我天。。要死了。。

对比了线上的机器，发现人家根本就没装那个 setuptools_scm, 要不试下卸载了？

说干就干:

sudo pip uninstall setuptools_scm

咦，报错终于不是 too old 了，看来还真是那坑爹货的问题。既然说certifi版本不符合，那就重装下吧

然后就继续安装咯，

RuntimeError: maximum recursion depth exceeded in cmp

瞬间懵逼.. maximum recursion 最大递归错误都出现了。。直接谷歌，有人安装下get-pip-py`， 并没用

折腾好几次，还是这个问题， 仔细想了想这个是在安装了那个 certifi-2016.9.26之后出现的，会不会就是这个库本身的缺陷？

还是先更新到 certifi==2017.4.17 再看看，毫无疑问，肯定就是又会出现那个错误：

pkg_resources.VersionConflict: (certifi 2017.4.17 (/Library/Python/2.7/site-packages), Requirement.parse('certifi==2016.9.26'))

然后针对这个问题谷歌，查了好久，看到一个博主说，之前遇到相似的问题，原因就是他的distribute版本太老，尝试升级下这个库版本。

因为本身有安装，所以我们需要指定最新版本或者升级，直接去Pypi看看最新版本是什么？

Pypi地址：https://pypi.org/project/distribute/

看到最新版本是：distribute 0.7.3，所以直接安装

sudo pip install distribute==0.7.3
