Ubuntu 16.04.3 安装nvm

最近给一批执行机安装node环境，记录下过程

安装nvm

test1234@test1234:~$ wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.0/install.sh | bash
=> nvm is already installed in /home/test1234/.nvm, trying to update using git
=> error: pathspec 'v0.33.0' did not match any file(s) known to git.
=> Compressing and cleaning up git repository

=> nvm source string already in /home/test1234/.bashrc
=> bash_completion source string already in /home/test1234/.bashrc
=> Close and reopen your terminal to start using nvm or run the following to use it now:

export NVM_DIR="/home/test1234/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm

使环境变量生效

test1234@test1234:~$ source .bashrc

安装node

test1234@test1234:~$ nvm install 4.2.4
v4.2.4 is already installed.
Now using node v4.2.4 (npm v2.14.12)
