第一次安装nodejs时，编译prometheus时，抛错

npm ERR! code ELIFECYCLE
npm ERR! syscall spawn
npm ERR! file sh
npm ERR! errno ENOENT
npm ERR! codemirror-promql@0.19.0 build:lib: `bash ./build.sh`
npm ERR! spawn ENOENT
npm ERR! 
npm ERR! Failed at the codemirror-promql@0.19.0 build:lib script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
npm WARN Local package.json exists, but node_modules missing, did you mean to install?

查询资料后选择升级npm，但是升级时出现了开头的错误，但是这时候却卸载也卸载不掉，安装也无法安装，首先尝试了

• sudo rm -rf /usr/local/lib/node_modules
• sudo rm -rf ~/.npm
• brew uninstall --force node
• brew install node

但是无果，所以一气之下就把开头抛错的/Users/XXXX/tenv/node/v14.4.0/lib/node_modules/npm文件夹删掉了，然后重新走了第一次尝试的流程，结果ok了，芜湖
