最后发现是pcre-devel在捣鬼，卸载

?

1	yum remove pcre-devel

　　

关联卸载了两个东西

?

1 2	Erasing    : php56w-devel-5.6.40-1.w6.x86_64                                                                                                     1/2 Erasing    : pcre-devel-7.8-7.el6.x86_64

再安装，没问题：

?

1	python36 -m pip install  uwsgi
