问题描述
我正在将IronPython嵌入到我的应用程序中.一切正常，但是我发现当我使用CreateScriptSourceFromFile执行文件时，似乎IronPython缓存了其他导入的模块.
I'm embedding IronPython in my application. Everything goes fine but I found that when I use CreateScriptSourceFromFile to execute a file, it seems that IronPython cached other imported module.
例如，我有另一个文件为foo.py:
For example I have another file as foo.py:
foo = 'foo'
然后我使用IronPython托管API执行bar.py:
And I use IronPython hosting API to execute bar.py:
from foo import foo
print foo
如果我对bar.py进行了更改，那么在不退出主机应用程序的情况下，我可以看到所做的更改生效.但是，如果编辑foo.py，则必须重新启动应用程序才能看到更改.我已经在选项中启用了Debug，但无济于事.
If I make changes to bar.py then without exiting the host application I can see my changes made take effect. But if I edit foo.py then I have to reboot my application to see the changes. I've already enabled Debug in the options but it does not help.
请咨询.非常感谢.
推荐答案
是的，导入的模块由ScriptEngine实例缓存.如果要自动重新加载缓存的模块，则必须创建一个新的引擎实例.当前无法禁用它并始终重新加载模块.
Yes, imported modules are cached by the ScriptEngine instance. You'll have to create a new engine instance if you want to reload cached modules automatically. There's currently no way to disable that and always reload modules.
禁用缓存行为的选项不是一个坏主意； 打开问题，以便引起关注.补丁当然更好.
An option to disable the caching behaviour isn't a bad idea; open an issue so that it's on the radar. Patches are even better, of course.
