=> Appending nvm source string to /Users/cony/.zshrc
=> bash_completion source string already in /Users/cony/.zshrc
=> Close and reopen your terminal to start using nvm or run the following to use it now:
export NVM_DIR="/Users/cony/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
3、根据提示执行命令load nvm
[root@mini ~]# soft export NVM_DIR="/Users/cony/.nvm"
[root@mini ~]# soft [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
[root@mini ~]# soft nvm
Node Version Manager
Note: <version> refers to any version-like string nvm understands. This includes:
- full or partial version numbers, starting with an optional "v" (0.10, v0.1.2, v1)
- default (built-in) aliases: node, stable, unstable, iojs, system
- custom aliases you define with `nvm alias foo`
Any options that produce colorized output should respect the `--no-colors` option.

Now using node v7.5.0 (npm v4.1.2)
Creating default alias: default -> node (-> v7.5.0)
5、验证node及npm版本
[root@mini ~]# soft node -v
v7.5.0
[root@mini ~]# soft npm -v
