执行 ionic serve 时出错 [英] I have an error when executing ionic serve

问题描述

当我执行 ionic serve 时，显示以下错误:

When I execute ionic serve, it shows the following errors:

拒绝加载图像 'http://localhost:8100/favicon.ico' 因为它违反了以下内容安全策略指令:默认-src '无'".请注意，'img-src' 没有明确设置，所以'default-src' 用作后备.

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.

加载资源失败:服务器响应404 状态(未找到)

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

我该如何解决这个问题?

How can I solve this?

向我展示了一堆错误，都与此类似

showed me a bunch of errors, all similar to this

[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:

这使我通过

npm install node-sass --save

npm install node-sass --save

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

The compilation process is sometimes spitting out rather confusing error messages from time to time, but with a little digging one can start guessing where to start poking
