node.js - Node 看不到包，路径错误

Question

我正在尝试设置和运行 microtime package ，但 Node 引发错误:

npm install microtime

ubuntu@ubuntu-desktop:~$ node
> var microtime = require('microtime')
Error: Could not load the bindings file. Tried:
 -> /home/ubuntu/node_modules/microtime/build/Debug/microtime.node

路径似乎有问题，但我不知道去哪里挖掘来解决这个问题(我是 linux 新手)

我的配置是:ubuntu 10.04，node 0.6.13，npm 1.1.10

2@Linus:嗯，我刚刚尝试重新安装 microtime，现在出现错误(但第一次不是):

ubuntu@ubuntu-desktop:~/app1$ npm install microtime
npm http GET https://registry.npmjs.org/microtime
npm http 304 https://registry.npmjs.org/microtime
npm http GET https://registry.npmjs.org/bindings
npm http 304 https://registry.npmjs.org/bindings

> microtime@0.3.1 install /home/ubuntu/node_modules/microtime
> node-gyp rebuild

info it worked if it ends with ok

Answer 1

这是您问题的根源:

make: g++: Command not found

你需要

apt-get install build-essential

然后尝试重新安装。对您的发行版使用 sudo 或 super 用户来执行此操作。
