| 3 likuku 2018-11-25 00:56:11 +08:00 " Couldn't find a tree builder with the features you requested: html5lib" 这么明确的提示了吗... 缺啥就装啥啊。 确认你在你项目的目录下，确认使用你正确的 pyenv 或者 virtualenv 环境， pip search html5lib # 先确认 pip 库里有没有，我确认过了，有的。 pip install html5lib # 装完它之后，再试吧 |
 | 4 quinoa42 2018-11-25 07:08:03 +08:00 html5lib 并不是 beautifulsoap 的硬性依赖,要用的话得 pip install html5lib |
