First you'll need to make sure your system has a c++ compiler. For OSX, XCode will work, for Ubuntu, the build-essential and libssl-dev packages work.

To install you could use the install script using cURL:

curl https://raw.github.com/bojoer/nvm-extended/v0.1.0/install.sh | sh

or Wget:

wget -qO- https://raw.github.com/bojoer/nvm/v0.1.0/install.sh | sh

_{The script clones the nvm-extended repository to ~/.nvm-extended and adds the source line to your profile (~/.bash_profile, ~/.zshrc or ~/.profile).}

You can customize the install source, directory and profile using the NVME_SOURCE, NVME_DIR and NVME_PROFILE variables. Eg: curl ... | NVME_DIR=/usr/local/nvme sh for a global install.

_{NB. The installer can use Git, cURL or Wget to download NVM Extended, whatever is available.}

For manual install create a folder somewhere in your filesystem with the nvme.sh file inside it. I put mine in a folder called nvme.

Or if you have git installed, then just clone it:

git clone https://github.com/bojoer/nvm-extended.git ~/.nvm-extended

To activate nvme, you need to source it from your shell:

source ~/.nvm-extended/nvme.sh OR . ~/.nvm-extended/nvme.sh

I always add this line to my ~/.bashrc, ~/.bash_profile, ~/.bash_profile or ~/.zshrc file to have it automatically sourced upon login. Often I also put in a line to use a specific version of node.

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

nvme install 0.10

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

nvme use 0.10

You can create an .nvmerc file containing version number in the project root folder; run the following command to switch versions:

nvme use

Or you can just run it:

nvme run 0.10

If you want to see what versions are installed:

nvme ls

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

nvme ls-remote

To restore your PATH, you can deactivate it.

nvme deactivate

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

nvme alias default 0.10

To use a mirror of the node binaries, set $NVME_NODEJS_ORG_MIRROR:

export NVME_NODEJS_ORG_MIRROR=http://nodejs.org/dist
nvme install 0.10

NVME_NODEJS_ORG_MIRROR=http://nodejs.org/dist nvme install 0.10

Tests are written in Urchin. Install Urchin (and other dependencies) like so:

npm install

There are slow tests and fast tests. The slow tests do things like install node and check that the right versions are used. The fast tests fake this to test things like aliases and uninstalling. From the root of the nvme git repository, run the fast tests like this.

npm run test/fast

Run the slow tests like this.

npm run test/slow

Run all of the tests like this

npm test

Nota bene: Avoid running nvme while the tests are running.

To activate, you need to source bash_completion:

[ -r "$NVME_DIR/bash_completion" ] && . "$NVME_DIR/bash_completion"

Put the above sourcing line just below the sourcing line for NVM Extended in your profile (.bashrc, .bash_profile or `.profile).

nvme

$ nvme [tab][tab]
alias          copy-packages  help           list           run            uninstall      version
clear-cache    deactivate     install        ls             unalias        use

nvme alias

$ nvme alias [tab][tab]
default

$ nvme alias my_alias [tab][tab]
v0.4.11        v0.4.12       v0.6.14

nvme use

$ nvme use [tab][tab]
my_alias        default        v0.4.11        v0.4.12       v0.6.14

nvme uninstall

$ nvme uninstall [tab][tab]
my_alias        default        v0.4.11        v0.4.12       v0.6.14

If you try to install a node version and the installation fails, be sure to delete the node downloads from src (~/.nvm-extended/src/) or you might get an error when trying to reinstall them again or you might get an error like the following:

curl: (33) HTTP server doesn't seem to support byte ranges. Cannot resume.

Where's my 'sudo node'? Checkout this link:

nvm-sh/nvm#43

on Arch Linux and other systems using python3 by default, before running install you need to

  export PYTHON=python2

After the v0.8.6 release of Node.js, nvme tries to install from binary packages. But in some systems, the official binary packages don't work due to incompatibility of shared libs. In such cases, use -s option to force install from source:

nvme install -s 0.8.6
