导读：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）

咦，需要装这个包setuptools-scm，直接无脑装

sudo pip install setuptools-scm

我天。。隐约察觉到有点不对劲，这什么鬼。。 too old ?？所以要我先升级下？

sudo pip install --upgrade setuptools

这次没毛病了吧？装我的 lz4

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：

sudo pip install -U pip setuptools wheel

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

Uninstalling setuptools-scm-2.1.0:
