npm不会安装快递？

Question

我目前有node.js版本0.8.8,并安装了npm 1.1.59.

每当我跑:

$ npm install -g express

我得到了这个回报:

npm ERR! Error: EACCES, open '/Users/devinandrews/.npm/64a534c1-express.lock'
npm ERR!  { [Error: EACCES, open '/Users/devinandrews/.npm/64a534c1-express.lock']

我现在正拉着我的头发试图解决这个问题.

更新:

我跑了

$ npm -g ls

但如果我跑:

$ npm ls

它返回空？

Answer 1

我有同样的问题,并npm cache clear没有解决它.导致此问题的原因是主.npm目录中的目录是使用root权限创建的.很可能你运行的第一个npm命令是sudo npm -g,现在你正在尝试npm install在本地目录中.

要解决:

• sudo chown -R yourusername ~/.npm
• 这可能没有必要,但我也必须这样做 rmdir ~/tmp

npm install 来自package.json应该在此之后工作.

Answer 2

运行npm cache clean 并尝试再次安装它

Answer 3

我遇到了同样的问题,导致此问题的原因是您的主目录中的.npm目录是使用root权限创建的.

使用 :

$sudo npm install -g express
