ionic-framework - 执行 ionic serve 时出错

Question

当我执行 ionic serve 时，它​​显示以下错误:

Refused to load the image 'http://localhost:8100/favicon.ico' because it violates the following Content Security Policy directive: "default-src 'none'". Note that 'img-src' was not explicitly set, so 'default-src' is used as a fallback.

Failed to load resource: the server responded with a status of 404 (Not Found)

我该如何解决这个问题？

Answer 1

我有同样的错误信息。

查看执行时打印的日志

ionic serve

向我展示了一堆错误，都与此类似

[ng] ERROR in ./src/global.scss (./node_modules/@angular-devkit/build-angular/src/angular-cli-files/plugins/raw-css-loader.js!./node_modules/postcss-loader/src??embedded!./node_modules/sass-loader/lib/loader.js??ref--14-3!./src/global.scss)

[ng] Module build failed (from ./node_modules/sass-loader/lib/loader.js):

[ng] Error: Cannot find module 'node-sass'

[ng] Require stack:

这使我重新启动并运行应用程序

npm install node-sass --save

编译过程有时会不时地吐出相当困惑的错误消息，但稍微挖掘一下就可以开始猜测从哪里开始戳
