我遵循了这个github的故事：https://github.com/angular/angular-cli/wiki/stories-configure-hmr
当我执行ng serve（环境是开发）时，我能够看到自动刷新后的更改，但是对于ng serve --hmr -e=hmr，页面会自动刷新（如闪烁）而不进行更改。我必须按F5才能看到更改。
HMR工作正常，因为我看到我的终端输出如下：
NOTICE Hot Module Replacement (HMR) is enabled for the dev server.
The project will still live reload when HMR is enabled,
but to take advantage of HMR additional application code is required
(not included in an Angular CLI project by default).
See https://webpack.github.io/docs/hot-module-replacement.html
for information on working with HMR for Webpack.
To disable this warning use "ng set --global warnings.hmrWarning=false"
** NG Live Development Server is listening on localhost:4200, open your browser on http://localhost:4200 **

我也看到了HMR的控制台输出。我还能做些什么来充分利用HMR？
我已经尝试过：
我禁用了WebStorm的“安全写入”形式。
我删除并重新安装了node_modules.
