インストール完了実行:

source ~/.nvm/nvm.sh

使用方法の概要:
To download、comple、and install the latest v 0.1.x release of node、do this:

nvm install 0.10

And then in any new shell juse the installed version:

nvm use 0.10

Or you can just run it:

nvm run 0.10 --version

Or,you can run any arbitrry command in a subshell with the desired version of node:

nvm exec 0.10 node --version

You can also get the path to the executable to where it was installed:

nvm which 0.10

In place of a version pointer like“0.10”、you can use the special default aliases“stable”and“unstable”:

nvm install stable
nvm install unstable
nvm use stable
nvm run unstable --version

If you want to install io.js:

nvm install iojs

If you want to use the system-innstalled version of node,you can use the special default alias「system」:

nvm use system
nvm run system --version

If you want to see what versions are installed:

nvm ls

If you want to see what versions are available to install:

nvm ls-remote

To restore your PATH,you can deactivate it.

nvm deactivate

To set a default Node version to be used in any new shell、use the alias'default'

nvm alias default stable

To use a mirror of the node binaries、set $NVM_NODEJS_ORG_MIRROR:

export NVM_NODEJS_ORG_MIRROR=https://nodejs.org/dist
nvm install 0.10

NVM_NODEJS_ORG_MIRROR=https://nodejs.org/dist nvm install 0.10

To use a mirror of the iojs binaries、set $NVM_IOJS_ORG_MIRROR:

export NVM_IOJS_ORG_MIRROR=https://iojs.org/dist
nvm install iojs-v1.0.3

NVM_IOJS_ORG_MIRROR=https://iojs.org/dist nvm install iojs-v1.0.3

nvm use will not,by default,create a“current”symlink.Set $NVM_SYMLINK_CURRENT to“true”to enable this behavior,which is sometimes useful for IDEs.
