在 macOS Mojave 上全局安装 nodemon 时出现问题

Question

In the Visual Studio Code terminal I issue to following command:

npm install -g nodemon

The result in terminal is:

npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules
npm ERR! code EACCES
npm ERR! syscall access
npm ERR! path /usr/local/lib/node_modules
npm ERR! errno -13

How can I solve it?

Answer 1

安装前使用 sudo，它会要求输入凭据并完成

sudo npm i - g nodemon

Answer 2

This means that you do not have root privileges / are not a superuser. You have two ways to solve this.

• Use sudo before the command - this will usually then ask for credentials and run the command without a problem (hopefully)
• Run sudo -s to automatically run commands with sudo every time in the current terminal window (will deactivate once the terminal has been closed)
• Run sudo su which will make the computer think that the current terminal window has been opened by a root user (again will deactivate once current window has been closed)
