pip3 install uwsgi 报错

  ERROR: Failed building wheel for uwsgi
  Running setup.py clean for uwsgi
Failed to build uwsgi
DEPRECATION: Could not build wheels for uwsgi which do not use PEP 517. pip will fall back to legacy 'setup.py install' for these. pip 21.0 will remove support for this functionality. A possible replacement is to fix the wheel build issue reported above. You can find discussion regarding this at https://github.com/pypa/pip/issues/8368.

最后发现是pcre-devel在捣鬼，卸载

yum remove pcre-devel

　　

关联卸载了两个东西

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：

python36 -m pip install  uwsgi
