## Installation
|
||||
|
||||
First you'll need to make sure your system has a c++ compiler. For OSX, XCode will work, for Ubuntu, the build-essential package works. You'll also need `git` if you want to track HEAD.

|

|
||||
To install create a folder somewhere in your filesystem with the "`nvm.sh`" file inside it. I put mine in a folder called "`.nvm`".

|
|||
|
||||
git clone git://github.com/creationix/nvm.git ~/.nvm
|
||||
|
||||
Then add two lines to your bash profile:
|
||||
|
||||
NVM_DIR=$HOME/.nvm
|
||||
. $NVM_DIR/nvm.sh
|
||||
nvm use
|
||||
|
||||
The first line loads the `nvm` function into your bash shell so that it's available as a command. The second line sets your default node version to the latest released version.
|
||||
To activate nvm, you need to source it from your bash shell
|
||||
|
||||
. ~/.nvm/nvm.sh
|
||||
|
||||
## Usage
|
||||
|
||||
To download, install, and use the v0.1.94 release of node do this:
|
||||
To download, install, and use the v0.2.5 release of node do this:
|
||||
|
||||
nvm install v0.1.94
|
||||
nvm install v0.2.5
|
||||
|
||||
And then in any new shell just use the installed version:
|
||||
|
||||
nvm use v0.1.94
|
||||
|
||||
If you want to track HEAD then use the clone command:
|
||||
|
||||
nvm clone
|
||||
|
||||
Then in any new shell you can get this version with:
|
||||
|
||||
nvm use HEAD
|
||||
|
||||
When you want to grab the latest from the node repo do:
|
||||
|
||||
nvm update
|
||||
nvm use v0.2.5
|
||||
|
||||
If you want to see what versions you have installed issue:
|
||||
|
||||
nvm list
|
||||
nvm ls
|
||||
|
||||
To restore your PATH, you can deactivate it.
|
||||
|
||||
nvm deactivate
|
||||
|
||||
If you want to install nvm to somewhere other than `$HOME/.nvm`, then set the `$NVM_DIR` environment variable before sourcing the nvm.sh file.
