Question

我正在尝试运行由同事创建的Angular程序。我遇到了同样的错误，“ serve命令需要在Angular项目中运行，但是找不到项目定义。” 这是在运行“ npm install”和“ npm start”命令之后，尽管遵循了我能找到的所有建议。

我的软件信息： Angular CLI：7.3.9 节点：10.15.3 操作系统：Darwin x64 角度：7.2.15 @角度/ cli 7.3.9 打字稿3.2.4

注意：在package.json文件中，其内容如下所示，以表明“ ng start”脚本是使用ng serve命令运行的（据我所知）。

}

注意：仅当我运行“ ng start”命令时，才会出现以下错误。如果我使用“ ng serve”命令，则错误很简单，即“ serve命令需要在Angular项目中运行，但找不到项目定义。”

我尝试了以下建议：
    -验证根文件夹
    -验证angular.json和angular-cli.json文件是否存在
    -验证TS版本的兼容性
    -更新当前的角度cli

ng更新@ angular / cli-仅迁移--from = （也通过ng update --all --force）

-卸载/重新安装/验证缓存

npm卸载-g @ angular / cli
  npm缓存验证
  npm install -g @ angular / cli @ latest

由于某些原因，尽管我付出了很多努力，但我仍遇到Angular软件和相关软件包的问题。

任何其他建议，我们将不胜感激！

Answer 1

随着错误的出现

Error: Twit config must include `consumer_key` when using user auth.
at /Users/leonaadriennestephanieponce/Downloads/TwitterAPI-master/node_modules/twit/lib/twitter.js:511:13

您是否在twit Twitter api调用配置中提供了consumer_key？否则，它将在正确命名的函数_validateConfigOrThrow中引发错误。 511行也适用于此：check source code of twit

Answer 2

这对我有用

npm卸载@ angular / cli npm缓存验证 npm install -g @ angular / cli

Angular CLI错误：找不到项目定义
