我重新上传了

我试了下你的代码，应该没啥问题的，应该是浏览器插件没装对，你有安装吗

可以的，其实就是把 node_modules 目录删除掉试下先

rm node_modules

重新 yarn install 试一下，

看起来好像是 initState 是不是没有写对，如何构建 store 那个文件，看下

{
  "name": "frontend",
  "version": "0.1.0",
  "private": true,
  "proxy": "http://127.0.0.1:5001",

    "extends": [

      "react-app/jest"
    ]
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

其实把证书 安装到 /srv/docker/gitlab/gitlab/certs/ 会更直接些

acme.sh --installcert -d gitlab.rails365.net \
               --keypath       /srv/docker/gitlab/gitlab/certs/gitlab.key  \
               --fullchainpath /srv/docker/gitlab/gitlab/certs/gitlab.crt \
               --reloadcmd     "sudo nginx -s reload"
openssl dhparam -out /srv/docker/gitlab/gitlab/certs/dhparam.pem 2048

好，后面应该没问题的

这个库也换下 "react-router-bootstrap": "0.25.0",

你退回到安装这个库的视频那边， 5.2.0 这个版本
