Question

unirest支持python3吗？我用谷歌搜索，零信息出现。即使在the unirest documentation中，它也没有说它只是2.x，这使我相信它支持3.x和2.x.但是安装失败了3.4并且成功用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。

该项目不兼容Python 3。如果项目没有明确说明（不在setup.py数据库分类器或文档中），那么您必须查看source code。

我找到了：

no use_2to3 use in setup自动重写安装上的代码
imports for urllib2，一个仅限Python 2的库。

项目取决于poster library，也是urllib2 specific。

我改用requests library。它支持Python 3开箱即用，除异步请求外，它支持相同的功能集（但更好，因为它没有带来的缺点urllib2）。对于异步请求，您可以添加requests-futures。

unirest是否支持python3？
