角度 6，构建无法在 Firebase 托管上加载图像

Question

将 Angular 应用程序部署到 Firebase 托管后，我无法从 assets 文件夹中加载图像。 （构建--prod） 在本地主机上运行时，图像显示。 所有其他东西都正确加载。 这是我的包 json cli：~6.2.0-beta.2 firebase 工具：4.1.0

  }
}

在 appComponent 上试过

<img src="../assets/image.jpg">
<img src="/assets/image.jpg">
<img src="assets/image.jpg">

这些都不起作用。

firebase.json 中的托管设置

"hosting": {
"public": "dist",
"ignore": [
  "firebase.json",
  "**/.*",
  "**/node_modules/**"
],
"rewrites": [
  {
    "source": "**",
    "destination": "/index.html"
  }
]}

Firebase 有什么技巧吗？重写？有人可以帮助我！

Answer 1

firebase 部署后，现在从 Angular 6.1.3 中的资产加载图像！终于找到了解决方案，它对我有用。问题是 tsconfig.json 更改：

"outDir": "./dist/out-tsc",

到：

"outDir": "./dist",

Answer 2

在部署到 Firebase 托管后，我在静态资产方面遇到了同样的问题，即使它们在从 localhost 提供服务时运行良好。我必须从
<img src="/src/assets/img/pricing_comparison.PNG"> 更改为
<img src="/assets/img/pricing_comparison.PNG">。

（p.s. 我尝试根据接受的答案更改我的 tsconfig.json 文件，但这并没有改变或解决我的错误）

Answer 3

我也有同样的问题。这是我尝试过的解决方案

1. 打开 tsconfig.json 更改：

   "outDir": "./dist/out-tsc",

   到：

   "outDir": "./dist"

2. 打开 angular.json。确保资产配置如下所示

       "assets": [
          "src/favicon.ico",
          "src/assets"
        ],

1. img 标签的变化<br> src="/src/assets/img/pricing_comparison.PNG" 到 <br> src="/assets/img/pricing_comparison.PNG"。

Answer 4

如果你在本地工作

只要使用 url 就可以了

#login {
    background-image: url('/assets/app-assets/img/gallery/login-bg.jpg');
    background-size: 100% 100%;
    background-repeat: no-repeat;
  }

在您的 CSS 或 html 组件中，这对我有用。 只需将图片网址从/src/assets/your_image.png 更改为/assets/your_image.png

这是我的角度版本
