python-3.x - unirest 支持 python3 吗？

Question

unirest 支持 python3 吗？我用谷歌搜索，出现零信息。即使在 the unirest documentation它并没有说它只是 2.x，这让我相信它同时支持 3.x 和 2.x。但是，安装 3.4 失败并成功安装 2.7。见下文。

目前我使用的是 2.7，但我更喜欢将 3.x 用于新项目。

Answer 1

该项目与 Python 3 不兼容。当项目没有明确说明这一点时(既不在 setup.py 宝库分类器中也不在文档中)，您将不得不查看 source code .

我发现:

• no use_2to3 use in setup在安装时自动重写代码
• imports for urllib2 ，一个仅限 Python 2 的库。

项目依赖poster library , 这也是 urllib2 specific .

我会使用 requests library反而。它开箱即用地支持 Python 3，除了异步请求外，它还支持相同的功能集(但更好，因为它没有 urllib2 带来的缺点)。对于异步请求，可以在requests-futures上加上.
