CherryPy Autoloader 死于 bcrypt

Question

我在 CherryPy 上有纯项目，希望 AuthTool 使用 bcrypt 模块进行密码处理。

但是当我将 "import bcrypt" 行放入 AuthTool.py 时，CherryPy 告诉我：

[17/Nov/2017:17:55:57] ENGINE Error in background task thread function <bound method Autoreloader.run of <cherrypy.process.plugins.Autoreloader object at 0x0000026948C82E80>>.
AttributeError: cffi library '_bcrypt' has no function, constant or global variable named '__loader__'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\Serge\AppData\Local\Programs\Python\Python36\lib\site-packages\cherrypy\process\plugins.py", line 519, in run
    self.function(*self.args, **self.kwargs)
  File "C:\Users\Serge\AppData\Local\Programs\Python\Python36\lib\site-packages\cherrypy\process\plugins.py", line 651, in run
    for filename in self.sysfiles() | self.files:
  File "C:\Users\Serge\AppData\Local\Programs\Python\Python36\lib\site-packages\cherrypy\process\plugins.py", line 635, in sysfiles
    hasattr(m, '__loader__') and
SystemError: <built-in function hasattr> returned a result with an error set

Exception in thread Autoreloader:
AttributeError: cffi library '_bcrypt' has no function, constant or global variable named '__loader__'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\Serge\AppData\Local\Programs\Python\Python36\lib\threading.py", line 916, in _bootstrap_inner
    self.run()
  File "C:\Users\Serge\AppData\Local\Programs\Python\Python36\lib\site-packages\cherrypy\process\plugins.py", line 519, in run
    self.function(*self.args, **self.kwargs)
  File "C:\Users\Serge\AppData\Local\Programs\Python\Python36\lib\site-packages\cherrypy\process\plugins.py", line 651, in run
    for filename in self.sysfiles() | self.files:
  File "C:\Users\Serge\AppData\Local\Programs\Python\Python36\lib\site-packages\cherrypy\process\plugins.py", line 635, in sysfiles
    hasattr(m, '__loader__') and
SystemError: <built-in function hasattr> returned a result with an error set

在那之后一切正常，但自动加载器。我有 bcrypt (3.1.4) 和 CherryPy (11.1.0)。

我可以做些什么来解决这个自动加载器的问题吗？谢谢

Answer 1

您可以禁用自动加载器。将 'engine.autoloader.on' 设置为 False。当然，当监视的文件发生更改时，您将失去自动加载，因此您需要在每次更改时手动重新启动服务器。另一种方法是将服务器置于生产模式。查看可用模式及其作用：http://docs.cherrypy.org/en/latest/config.html#id14

顺便说一句：我发现 cherrypy (13.0.0) 和密码学 (2.1.4) 存在类似问题
