角度升级从5到6：资产路径必须从项目源根开始

时间：2018-05-06 18:13:07

标签： angular font-awesome

我将现有应用从Angular 5升级到了6.

运行ng serve后，我收到以下错误：

  

node_modules / font-awesome / fonts资源路径必须以   项目源根。错误：node_modules / font-awesome / fonts资产   path必须以项目源根开头。       at assetPatterns.map.assetPattern（/home/kay/Documents/<>/<>/node_modules/@angular-devkit/build-angular/src/utils/normalize-asset-patterns.js:37:23 ）

如下所示，我有一个资产数组，它从节点模块包中提取字体。这在Angular 5中不是问题。

好的，试试这个：

"assets": [
    {"glob": "**/*", "input": "./node_modules/youpackage", "output": "/where_you_want_theasset/"}
]

参考： https://github.com/angular/angular-cli/blob/master/docs/documentation/stories/asset-configuration.md

原始答案： 因为它帮助了我（我的所有资产都在src中）

更新后我得到了同样的错误，

尝试将应用的根添加到angular.json

对我来说，sourceRoot和root是相同的

"root": "src",
  "sourceRoot": "src",
像这样：

{
  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
  "version": 1,
  "newProjectRoot": "projects",
  "projects": {
    "demo": {
      "root": "src",
      "sourceRoot": "src",
      "projectType": "application",
      "architect": {
        "build": {
          "builder": "@angular-devkit/build-angular:browser",

好吧， 澄清Abann的解决方案。 对于sourceRoot以外的资产，您必须使用长格式。我确实认为documentation对此可能更加清楚。声明

  

您可以使用此扩展配置从项目外部复制资产。例如，您可以从节点程序包中复制资产：

但实际上，它应该说您必须使用 

"assets": [
          "src/assets",
          "src/favicon.ico",
           {
            "glob": "*",
            "input": "node_modules/font-awesome/fonts",
            "output": "assets/fonts/"
          }
        ],

assets/fonts/是您可能在SASS / SCSS文件的$fa-font-path变量替代中配置的路径。

将sourceRoot更改为＆＃39;。＆＃39;似乎已经解决了这个并允许我编译，并且表面测试显示一切正常。但不相信这不会引入其他意想不到的后果。

答案 3 :(得分：0)

我将项目升级到角度6.x后得到了相同的错误消息。我的项目引用了PrimeNG，它使用了字体很棒。将PrimeNG升级到6.0.0-alpha.2后，错误已经消失（他们努力工作以获得角色6官方支持）。

因此，如果您遇到此问题，请验证您的依赖项是否也支持Angular 6.x，并且已安装的软件包是最新的。

这是真的，但是必须写一些不同的东西。这对我有用，在我的有角JSON中

<div class="status" ng-repeat="emp in groups" ng-attr-id="{{emp[attr]}}">
</div>

div.status:not(:first-child) {
  display: none;
}

在将新项目添加到现有工作区并将开发配置从现有项目的The src/assets asset path must start with the project source root部分复制并粘贴到新项目的serve部分之后，我收到了serve错误消息我的angular.json文件中的项目，但无法更新browserTarget属性以反映新项目的名称。错误消息抱怨现有项目，这对我来说似乎很奇怪，因为我确定我没有修改与该项目有关的任何内容。

错误

请注意，projects.project2.architect.serve.configurations.development.browserTarget的值为project1:build:development，而不是project2:build:development。
