node.js - 使用 npm 安装 Express 时出错

Question

我已经使用安装了express

npm install express

但看起来为了创建应用程序，我应该全局安装它。所以我用了:

npm install -g express

但收到:

npm ERR! Error: EACCES, mkdir '/usr/lib/node_modules/express'
npm ERR!  { [Error: EACCES, mkdir '/usr/lib/node_modules/express']
npm ERR!   errno: 3,

npm ERR! 
npm ERR! Additional logging details can be found in:

然后尝试 sudo 后:

sudo npm install -g express

我明白了:

axconfig: unable to open axports file /etc/ax25/axports (No such file or directory)

这是为什么？？？

正如错误明确指出的那样，您没有在/usr/lib 中创建的权限。 堆栈错误:EACCES，mkdir '/usr/lib/node_modules/express'

因此使用 sudo 权限安装..

sudo npm install -g express
