我已经尝试了所有选项更改我的版本打字稿来自＆＃34; 2.4.2＆＃34;到＆＃34; 2.4.1＆＃34; 另外，我已经单独执行了#t; npm run serve＆＃34;和＃34; npm run build：watch＆＃34;但它不起作用。我已将环境设定为可变，但根本不起作用。 请帮忙解决这个问题。

27 error Make sure you have the latest version of node.js and npm installed.
27 error If you do, this is most likely a problem with the angular-quickstart package,
27 error not with npm itself.
27 error Tell the author that this fails on your system:
27 error concurrently "npm run build:watch" "npm run serve"
27 error You can get information on how to open an issue for this project with:
27 error npm bugs angular-quickstart
27 error Or if that isn't available, you can get their info via:
27 error npm owner ls angular-quickstart

答案 0 :(得分：0)
遇到相同的问题，将“ cmd.exe”添加到解决该问题的路径中，如果您在 windows 上，只需在“ 环境变量”中添加此行：“ C：\ Windows \ System32”
希望对您有所帮助！
