Now we have mitmweb shipped with our release, if you just want to try mitmweb, follows the step shows in [http://docs.mitmproxy.org/en/stable/install.html](http://docs.mitmproxy.org/en/stable/install.html) and then you could type “mitmweb” in your terminal, the Web UI will show up with your browser. `npm install` and `gulp` is for the developing environment. (but seems we don’t have mitmweb shipped with the windows version now)

先按照这里 [https://github.com/mitmproxy/mitmproxy#development-setup](https://github.com/mitmproxy/mitmproxy#development-setup) 配置好开发环境， 然后在web目录下面执行npm install 安装依赖，再运行gulp。  
接着. venv/bin/activate 进入python虚拟环境后执行mitmweb命令，如果没有出错，浏览器会被自动唤醒并且跳转到web ui的界面。
