答

我猜您在安装 mongodb 库时没有可用的 make 工具.我建议你这样做

I guess you did not have the make tools available when you installed your mongodb library. I suggest you do

xcode-select --install(在 Mac 上)或 sudo apt-get install gcc make build-essential(在 ubuntu 上)

xcode-select --install (on a mac) or sudo apt-get install gcc make build-essential (on ubuntu)

然后运行

rm -rf node_modules
npm cache clean
npm install

或者只是基于@tobias 评论的 npm 更新(安装 build-essential 之后)

OR just npm update based on @tobias comment (after installing build-essential)

npm update
