我必须在笔记本电脑上重新安装Mac OS X Mavericks。现在npm不起作用。但是， Node 仍在便携式计算机上，而npm在$ PATH中。
christohersmbp3:angular-phonecat christopherspears$ npm install
-bash: npm: command not found
christohersmbp3:angular-phonecat christopherspears$ node --version
v0.10.26
christohersmbp3:angular-phonecat christopherspears$ npm start
-bash: npm: command not found
christohersmbp3:angular-phonecat christopherspears$ echo $PATH
/usr/local/share/python:/Users/christopherspears/.rbenv/bin:/Users/christopherspears/bin:/usr/local/heroku/bin:/usr/local/share/npm/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin
实际上，我能够轻松地运行 Node :
christohersmbp3:~ christopherspears$ node
> console.log('hello node');
hello node
undefined
>
(^C again to quit)
>
关于如何解决此问题的任何想法，还是应该重新安装Node.js？
更新:
我一直在尝试卸载并重新安装Node.js，但是遇到了一个问题:
christohersmbp3:angular-phonecat christopherspears$ brew uninstall node

我应该将所有者从24561更改为christopherspears吗？
更新:
我确实将AUTHORS文件的所有者更改为christopherspears。现在我收到此错误:
christohersmbp3:angular-phonecat christopherspears$ brew postinstall node
Error: Permission denied - /usr/local/lib/node_modules/npm/bin/node-gyp-bin/node-gyp
看起来像是同样的问题:
christohersmbp3:node-gyp-bin christopherspears$ ll

-rwxr-xr-x 1 24561 staff 61 Jan 28 19:21 node-gyp.cmd*
我是否必须对24561拥有的所有文件执行此操作？我希望不是。
更新:
啊。真la似乎我被要求将所有人的所有者从24561更改为我的用户名。为什么所有者首先设置为24561？
最佳答案
将所有者从24561更改为我的用户名后，我得到了npm的支持。
