某些图书馆以我不想要的方式更改我的 sys.path 。
Some library does change my sys.path in a way that I don't want it to.
但是我找不到它。受影响的virtualenv安装了很多库。
But I can't find it. The affected virtualenv has a lot of libraries installed.
我用一个改变了修改的类替换了sys.path,但这并没有帮助,因为代码似乎更改 sys.path 如下所示:
I replaced sys.path with a own class which alters the modifications, but this does not help, since the code seems to alter sys.path like this:
sys.path= [...] + sys.path我如何找到恶代码行及其堆栈跟踪?
How can I find the "evil" code line and its stack trace?

我发现这样的恶意代码行。
I found the evil code line like this.
我改变了sys.globals ['sys' ]在sitecustomize.py:
I alter sys.globals['sys'] in sitecustomize.py:
# sitecustomize.py import sys class AttributeIsReadonly(ValueError): pass class MakeModuleAttributesReadonly(object): def __init__(self, module, readonly_attributes): self.module=module self.readonly_attributes=readonly_attributes def __setattr__(self, item, value): if item in ['module', 'readonly_attributes']: return super(MakeModuleAttributesReadonly, self).__setattr__(item, value) if item in self.readonly_attributes: raise AttributeIsReadonly('Access on attribute %r is readonly' % item) return setattr(self.module, item, value) def __getattr__(self, item): return getattr(self.module, item) sys.modules['sys']=MakeModuleAttributesReadonly(sys, ['path']) #import sys #sys.path=sys.path # this will raise the above AttributeIsReadonly它引发 AttributeIsReadonly ,我看到代码行堆栈跟踪。
It raises AttributeIsReadonly and I see the code line and the stack trace.
