找不到“@/build-角:browser”构建器的节点包

Question

我正在尝试把我的应用程序部署到heroku。Heroku当地的网络运行得很好。我尝试过添加npm i@/build，但这并没有帮助，我在互联网上也找不到类似的东西。部署到Heroku可以很好地工作，直到它到达ng build命令，这个命令可以在角package.json内部的"postinstall“中找到。

package.json

{
  "name": "web",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "start": "node ./bin/www",
    "heroku-postbuild": "npm install && cd public && npm install @angular/cli -g && npm install",
    "heroku-cleanup": "cd ./public && patch-package"
  },

  },
  "engines": {

要尝试的一件事是重新安装软件包：

npm uninstall @angular-devkit/build-angular
npm install --save-dev @angular-devkit/build-angular

如果这不起作用，您可以尝试：

ng update @angular/cli @angular/core --allow-dirty --force
