尝试为Node.js安装npm时出错

Question

我正在学习Node.js,我在安装NPM(节点包管理器)时遇到了一些问题.我很确定这是一个权限或文件夹的东西...请注意我刚刚购买了一台Mac(我一生都使用过Windows)而且我对Mac终端非常不熟悉.

好的,我去使用NPM的一行安装:我收到了一个错误......curl http://npmjs.org/install.sh | sh

All clean!

这里显然有一个文件夹问题,也许我安装在错误的地方,我的节点文件夹在Users/Mike/node,当我尝试使用NODE_PATH找出我的节点路径变量时,我收到以下错误:

Michaels-MacBook-Pro:~ Mike$ node node/NODE_PATH  

node.js:203
        throw e; // process.nextTick error, or 'error' event on first tick
              ^
Error: Cannot find module '/Users/Mike/node/NODE_PATH'
    at Function._resolveFilename (module.js:334:11)
    at Function._load (module.js:279:25)
    at Array.<anonymous> (module.js:470:10)
    at EventEmitter._tickCallback (node.js:195:26)

有人可以告诉我我做错了什么吗？我是否需要像这样添加节点路径:

$ export PATH=/path/to/node/0.n.y/bin:${PATH}
$ curl http://npmjs.org/install.sh | sh

还是我让自己困惑？

Answer 1

权限/usr/local要求您使用sudo安装NPM或更改您的权限.在这三个中,我推荐第三个选项.

选项#1:使用 sudo

(请注意,NPM的创建者建议不要使用此方法)

curl http://npmjs.org/install.sh | sudo sh

选项#2:更改权限

sudo chmod g+rwx /usr/local
sudo chgrp admin /usr/local

选项#3:使用Homebrew

我建议安装Homebrew来管理在OS X上安装*nix工具(我远离MacPorts&Fink).安装Homebrew将设置权限,/usr/local以便您可以在不使用的情况下写入sudo.然后,您可以通过Homebrew安装Node,然后正常安装NPM:

brew install node --without-npm
curl http://npmjs.org/install.sh | sh
