是不是 pip/setuptools 版本太低了，装最新版试试

[Showfom]

pip install --upgrade pip
pip install --upgrade setuptools

更新一下先

[fxxkgw]

除了版本问题，基本上遇到的 pip 安装报错都是依赖的 devel 找不到，这种错误拿关键字去 google 里搜应该都可以找到。。

[dreampython]

问题已解决，解决方法是按照 @guyskk0x0 @Showfom 的方法，升级了 pip 和 setuptools 之后再执行 pip install bleach 后安装成功，感谢

[Showfom]

@dreampython 这是基本操作=。=
