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

还有一件事：当我将tsconfig.json的“target”选项从“es5”更改为“es6”时，app开始运行。 请帮忙。
答案 0 :(得分：2)
npm install --save-dev @types/core-js
在compilerOptions中的tsconfig中添加：
"typeRoots": [
"../node_modules/@types"
],
"types": [
"core-js"
]
