- 下载并运行安装脚本
$ curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.6/install.sh | bash
$ nvm --version
Note: On Linux, after running the install script, if you get nvm: command not found, simply close your current terminal, open a new terminal, and try verifying again. If it doesn't work, your system may not have a .bash_profile file where the command is set up. Simply create one with touch ~/.bash_profile and run the install script again. If the above doesn't fix the problem, open your .bash_profile and add the following line of code: source ~/.bashrc
