“easy_install"期间发出的警告 [英] warnings emitted during 'easy_install'

问题描述

当我easy_install一些python模块时，警告如:

When I easy_install some python modules, warnings such as:

<some module>: module references __file__
<some module>: module references __path__
<some module>: module MAY be using inspect.trace
<some module>: module MAY be using inspect.getsourcefile

有时会被发射.

这些消息来自哪里(什么包/源文件)?为什么引用 __file__ 或 __path__ 被认为是一件坏事?

Where (what package / source file) do these messages come from? Why is referencing __file__ or __path__ considered a bad thing?

推荐答案

easy_install 不喜欢使用 __file__ 和 __path__ 不是这样很大程度上是因为它们很危险，但因为使用它们的包裹几乎总是无法用完压缩鸡蛋.

easy_install doesn't like use of __file__ and __path__ not so much because they're dangerous, but because packages that use them almost always fail to run out of zipped eggs.

easy_install 是警告，因为它将效率较低"安装到解压缩目录而不是压缩鸡蛋中.

easy_install is warning because it'll install "less efficiently" into an unzipped directory instead of a zipped egg.

实际上，当 zip_safe 检查失败时，我通常会很高兴，因为如果我需要深入了解模块的源代码，那就容易多了.

In practice, I'm usually glad when the zip_safe check fails, because then if I need to dive into the source of a module it's a ton easier.
