去试试，把自己当前的19的gunicorn：
(RunningFast) ➜ staging gunicorn –version gunicorn (version 19.6.0) (RunningFast) ➜ staging which gunicorn /root/Envs/RunningFast/bin/gunicorn |
去降低为18
所以需要去了解：
搜：

参考：
pip uninstall gunicorn pip install gunicorn==18.0 |

再去看看gunicorn有哪些版本：
所以和18.0相近的，只有18.0版本，去试试：18.0
(RunningFast) ➜ staging pip install gunicorn==18.0 Collecting gunicorn==18.0 Downloading gunicorn-18.0.tar.gz (366kB) 100% |████████████████████████████████| 368kB 15kB/s Building wheels for collected packages: gunicorn Running setup.py bdist_wheel for gunicorn … done Stored in directory: /root/.cache/pip/wheels/64/07/89/e2dce813bea23a0ee108703f045bfd434597d3ed52671760a7 Successfully built gunicorn Installing collected packages: gunicorn Successfully installed gunicorn-18.0 |
【总结】
想要把gunicorn从最新的版本，降级到18.0版本，则可以：
先卸载最新的（19.6）的版本，再去安装指定的（18.0）的版本：
pip uninstall gunicorn pip install gunicorn==18.0 |
