角度升级从5到6:资产路径必须从项目源根开始

Question

我将现有的应用程序从Angular 5升级到6.

运行后ng serve我得到以下错误:

node_modules/font-awesome/fonts资源路径必须以项目源根目录开头.错误:node_modules/font-awesome/fonts资产路径必须以项目源根目录开头.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,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是一样的

"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",

好的，澄清Abann的解决方案。您必须对以外的资产使用长格式sourceRoot。我确实认为文档可能对此更加清晰。它指出

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/您可能在SASS / SCSS文件的$fa-font-path变量替代中配置的路径在哪里。
