解决方案
我想你在安装mongodb库时没有使用make工具。我建议你做
xcode-select --install
(在mac上)
或 sudo apt-get install gcc make build-essential
(在ubuntu上)
并运行
rm -rf node_modules
npm缓存清理
npm安装
或只是基于@tobias注释的npm更新(安装build-essential后)
npm update
A total node noob here. I've been trying to set up a sample node app but the following error keeps popping up every time I try to run:

解决方案
I guess you did not have the make tools available when you installed your mongodb library. I suggest you do
xcode-select --install
(on a mac)
or sudo apt-get install gcc make build-essential
(on ubuntu)
and run
rm -rf node_modules
npm cache clean
npm install
OR just npm update based on @tobias comment (after installing build-essential)
npm update
