百度搜索完全搜不到类似的问题，中文的技术文章清一色的复制粘贴，只能看到loguru的介绍文章，只能到外网查查看。

git上看到有说是 monkey.patch_all() 的问题。

Hi. Problems of compatibility with gevent are not new, see #258.

As the error message mentions contextvars, did you try calling monkey.patch_all(contextvars=False) instead?

然后有开发者回复了给参数加上 contextvars=False ,问题迎刃而解。

Another possibility is to import loguru after having called monkey.patch_all().

For Python < 3.7, Loguru depends on the contextvars library which perform some sanity checks for types (which therefore is not the one expected if ContextVar is patched by gevent).

另外有说先patch完再import loguru 包，也可以试一下看看。
