python - Cannot import name psyco_gevent

Question

I have an import error with

from psycogreen.gevent import psyco_gevent
psyco_gevent.make_psycopg_green()

it says:

ImportError: cannot import name psyco_gevent

I installed psycopg2 and psycogreen; and I followed this nice article about Django, Gevent, and Socket.io. This article also talks about it (it might be the source of the first article) and talks about a file named psyco_gevent.py on bitbucket which is not available anymore (404 error).

Answer 1

对于 psycogreen 来说，它看起来确实发生了一些变化。在 bitbucket 上查看： https ://bitbucket.org/dvarrazzo/psycogreen/overview

它看起来像这样的代码：

from psycogreen.gevent import psyco_gevent
psyco_gevent.make_psycopg_green()

应更改为与其他 psycogreen 调用相同：

from psycogreen.gevent import patch_psycopg
patch_psycopg()

Answer 2

当我导入名为的模型时，我遇到了类似的问题greenlet：

ImportError：无法导入名称“greenlet”

我不知道确切的原因，但我通过将文件名重命名greenlet.py为gl.py. 也许我们不能用模型的名字来命名文件。
