npm ERR ELIFECYCLE and ETARGET

Question

我该如何解决这两个错误？当我输入npm start时，出现此错误：

error Command failed with exit code 127.

npm ERR! code ELIFECYCLE

如果我输入npm install，则会出现此错误：

npm ERR! code ETARGET
npm ERR! notarget No matching version found for save-dev@^2.0.0.
npm ERR! notarget In most cases you or one of your dependencies are requesting

我该怎么办？

看来是因为您使用的是npm的旧版本。要将其升级到较新版本，请删除文件“ package-lock.json”并运行“ npm install”。
