设置 Odoo 12 开发者环境，Werkzeug 版本的问题

Question

我正在尝试使用 Pycharm 在 Ubuntu 版本 18.04 上使用 Python 3.7 virtualenv 设置 Odoo 12 实例。我不断收到与 Werkzeug 相关的问题，如下所示：

如果我使用写在 requirements.txt 文件中的所需版本的 werkzueg (Werkzeug==0.11.15)，我会收到此错误。我认为这个错误来自 werkzueg 的版本不支持 Python 3.7

During handling of the above exception, another exception occurred:

如果我使用最新版本的 werkzueg (Werkzeug==1.0.1)，我会收到此错误。

对不起，我不得不缩短错误日志，堆栈溢出给我一个错误，说邮件看起来像垃圾邮件。 任何帮助将不胜感激！

werkzeug.contrib 在 v1.0.0 中被移除。

将 requirements.txt 条目更改为

werkzeug==0.16.1

会起作用的。
