热模块更换后服务器无法访问（Webpack）

Question

当我做出改变时，我在终端看到了这一点：

[1] [piping] File src/containers/Blocks/Blocks.js has changed, reloading.
[0] webpack building...
[0] webpack built 67cf99a9b98c59d668ed in 3497ms

但在此之后，我再也无法做任何事了，如果我刷新我会看到：

GET http://blokdemo.localhost:3000/dashboard net::ERR_CONNECTION_REFUSED

它曾经有用，但自从我更新后：

"webpack": "^1.12.9",
"webpack-dev-middleware": "^1.4.0",
"webpack-hot-middleware": "^2.5.0"

到此：

"webpack": "^1.13.0",
"webpack-dev-middleware": "^1.6.1",
"webpack-hot-middleware": "^2.10.0",
"webpack-isomorphic-tools": "^2.2.50"

它不再起作用了。

这些是我用来运行的两个命令：

  "start-dev": {
      "command": "node ./bin/server.js",
      "env": {
        "NODE_PATH": "./src",
        "NODE_ENV": "development",
        "PORT": 3000,
        "APIHOST": "http://localhost:3333"
      }
    },
    "watch-client": {
      "command": "node webpack/webpack-dev-server.js",
      "env": {
        "UV_THREADPOOL_SIZE": 100,
        "NODE_PATH": "./src",
        "PORT": 3000
      }
    }

这是我的dev.config的链接：dev config

知道可能导致这种情况的原因吗？

提前致谢。
