使用方法概述：

To download, compile, and install the latest v0.10.x release of node, do this:

nvm install 0.10

And then in any new shell just use the installed version:

nvm use 0.10

Or you can just run it:

nvm run 0.10 --version

Or, you can run any arbitrary 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-installed 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.
