python - 错误 : gevent 1. 4.0 要求 greenlet>=0.4.14，但您将拥有不兼容的 greenlet 0.4.13

Question

我使用的是 Windows 10，我从源代码安装 Odoo ( https://github.com/odoo/odoo/tree/aa0554d224337e1d966479a351a3ed059d297765 )。Python版本

Python 3.8.0 (tags/v3.8.0:fa919fd, Oct 14 2019, 19:21:23) [MSC v.1916 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.

pip 版本

pip 19.3.1 from c:\program files (x86)\python38-32\lib\site-packages\pip (python 3.8)

我发现错误

如何解决？

Answer 1

您可以通过以下方式将 greenlet 升级到最新版本:

pip install --upgrade greenlet --ignore-installed greenlet

或者您可以通过以下方式安装任何特定版本:

pip install greenlet==0.4.14
