npm install -g @vue/cli

安装vue脚手架提示：

No command 'vue' found, did you mean:
Command 'vpe' from package 'texlive-latex-extra' (universe)
vue: command not found

解决方法：

1. Back up your computer.
2. On the command line, in your home directory, create a directory for global installations:

    mkdir ~/.npm-global
   

3. Configure npm to use the new directory path:

    npm config set prefix '~/.npm-global'
   

4. In your preferred text editor, open or create a ~/.profile file and add this line:

    export PATH=~/.npm-global/bin:$PATH
   

5. On the command line, update your system variables:

    source ~/.profile
   

6. To test your new configuration, install a package globally without using sudo:

    npm install -g jshint
   

Instead of steps 2-4, you can use the corresponding ENV variable (e.g. if you don’t want to modify ~/.profile):

    NPM_CONFIG_PREFIX=~/.npm-global
