我正在使用Azure WebApp，已经有几个星期了，突然间我无法继续使用管道，但失败并显示以下消息：
It looks like you're trying to use TypeScript but do not have typescript installed.
Please install typescript by running npm install typescript.
If you are not trying to use TypeScript, please remove the tsconfig.json file from your package root (and any TypeScript files).

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
实际上我正在使用打字稿，因为我从一开始就一直使用它，请帮忙吗？
