嗨，我在使用npm命令时遇到问题，无论我尝试什么，都遇到命令错误，无论我尝试ng服务如何，都遇到错误
在客户端中找不到模块@ angular-devkit / build-angular 所以我尝试安装@ angular-devkit / build-angular，然后出现波纹管错误

(or)
npm Uninstall @angular/cli

Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.
- configuration.entry should be one of these:
function | object { <key>: non-empty string | [non-empty string] } | non-empty string | [non-empty string]
-> The entry point(s) of the compilation.
Details:
* configuration.entry should be an instance of function
-> A Function returning an entry object, an entry string, an entry array or a promise to these things.
* configuration.entry['styles'] should be a string.
-> The string is resolved to a module which is loaded upon startup.

删除//注释包中的行：
//"@angular-builders/custom-webpack": "^7.0.0",
//"@angular-builders/dev-server": "^7.0.0",
如果需要在package.json中发表评论，请使用此选项：https://www.npmjs.com/package/x----x----x
最终输出如下：
//"x----x----x": "@angular-builders/custom-webpack, ^7.0.0",
//"x----x----x": "@angular-builders/dev-server, ^7.0.0",
然后，当您想重新添加这些软件包时，可以将它们转换回列表中的普通软件包。在此之前，包“ {x----x----x”基本上使它们成为注释。
