角度6到12迁移:获得多个警告: Css迷你插件：>意外"$“

Question

在将我的角6项目迁移到12之后，我在终端中得到了多个警告。

如果在angular.json中设置了优化:错误配置，那么所有的问题都会得到解决，但我不想做这些更改，这应该是真的。

通过优化:我确实收到了所有这些警告：-

早些时候，同样的代码在没有任何警告的情况下运行良好。

我也有同样的问题，我发现在我的例子中，angular.json上的资产配置是罪魁祸首。从配置中检查这段代码：

"architect": {
    "build": {
      "builder": "ngx-build-plus:build",
      "options": {
        "aot": true,
        "outputPath": "dist",
        "index": "src/index.html",
        "main": "src/main.ts",
        "tsConfig": "src/tsconfig.app.json",
        "polyfills": "src/polyfills.ts",
        "assets": [
          "src/assets",
          "src/favicon.ico"
        ]
}
}

在src/assets文件夹中有一堆样式表代码，scss、less、css，看起来CSS只是尝试以普通CSS的形式处理所有的东西。解决方案是从这些资产中移除任何未经处理的样式表，并将它们放在angular.json上的angular.json配置下。这对我起了作用，希望它也能帮到你！

您的问题与scss文件的处理有关。这个问题在67607413中有详细的描述。很快，如果从资产文件夹中删除或省略scss文件，这个问题将得到解决。我更喜欢省略SCSS文件。

"assets": [
    "src/favicon.ico",
    {
        "glob": "**/*",
        "input": "src/assets/",
        "ignore": ["**/*.scss"],
        "output": "/assets/"
    },
    ...
]

我也有同样的问题。您应该将‘assets//variables.scss’的导入更改为‘./assets/./variables.scss’。在我的例子中，它在styles.scss中，但是可以在每个.scss文件中。
