You may build the Node.js engine for any of the supported platforms.

For Windows and Mac some pre-built binaries are available; you may install them without building Node for yourself.

• GNU make 3.81 or newer. Pre-installed on most systems. Sometimes called gmake.

• python 2.6 or 2.7. The build tools distributed with Node run on python.

• libssl-dev (Node v0.6.x only.) Can usually be installed on *NIX systems with your favorite package manager. Pre-installed on OS X.

• libexecinfo (FreeBSD and OpenBSD only.) Required by V8. pkg_add -r libexecinfo installs it.

On UNIX platforms, make sure that the path doesn't contain whitespace: /home/user/My Projects/node won't work.

If you receive an error during ./configure like this

File "/home/flo/node-v0.6.6/tools/waf-light", line 157, in <module>
     import Scripting
File "/home/flo/node-v0.6.6/tools/wafadmin/Scripting.py", line 146
     except Utils.WafError, e:
                          ^
SyntaxError: invalid syntax

it is because Python3 is your default Python version. To fix this issue you have to set Python2 temporary as your default Python:

export PYTHON=`which python2`

Maybe you need to change your PYTHONHOME as well. If that doesn't work, you can try creating symlinks to the old python in a directory which comes before python's in $PATH:

cd /usr/local/bin
ln -s /usr/bin/python2 python
ln -s /usr/bin/python2-config python-config

Remember to remove the symlinks when you're done. If you have any further installation problems stop into #node.js on irc.freenode.net and ask questions.

If you are compiling on a NFS mount and get errors at the linker stage, try this:

make LINK=g++

There's a number of ways to install Node.js on Linux, instructions for installing Node.js on specific Linux distributions using a package manager can be found at: Installing Node.js via package manager.

The filenames vary with the Node's version. The following examples are for Node v0.6.18.

Do something like this

tar -zxf node-v0.6.18.tar.gz #Download this from nodejs.org
cd node-v0.6.18
./configure && make && sudo make install

Or, if you'd like to install from the repository

git clone https://github.com/joyent/node.git
cd node
git checkout v0.6.18 #Try checking nodejs.org for what the stable version is
./configure && make && sudo make install

You may wish to install Node in a custom folder instead of a global directory.

./configure --prefix=/opt/node && make && sudo make install

You can really speed up building process by adding -j argument with a number usually approximately equals number of cores plus one, so make -j 3 would be appropriate for dual-core processor.

You may want to put the node executables in your path as well for easier use. Add this line to your ~/.profile or ~/.bash_profile or ~/.bashrc or ~/.zshenv

export PATH=$PATH:/opt/node/bin

If you have SpiderMonkey installed, you may have some conflicting includes. Set CXXFLAGS="-I./deps/v8/src" before building to prioritize the v8 files over SpiderMonkey's.

Or use the one liner to install the latest node.js : bash < <(curl http://h3manth.com/njs)

It's easiest to use a package manager (as mentioned above) such as brew or macports.

1. Install Command Line Tools
   Xcode: Preferences->Downloads install Command Line Tools
   Note: I installed Xcode 4.5 in /Applications/Xcode

2. Download node.js src code

git clone https://github.com/joyent/node.git
cd node
git checkout v0.8.2

1. Compiling Source Code

export CC=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang
export CXX=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++
./configure && make && sudo make install

You need python and Microsoft Visual Studio but not OpenSSL. In cmd.exe do the following

C:\Users\ryan>tar -zxf node-v0.6.5.tar.gz
C:\Users\ryan>cd node-v0.6.5
C:\Users\ryan\node-v0.6.5>vcbuild.bat release
[Wait 20 minutes]
C:\Users\ryan\node-v0.6.5>Release\node.exe
> process.versions
{ node: '0.6.5',
  v8: '3.6.6.11',
  ares: '1.7.5-DEV',
  uv: '0.6',
  openssl: '0.9.8r' }
>

The executable will be in Release\node.exe.

You may obtain pre-compiled Node.js binaries for several platforms from http://nodejs.org/download.

Installing Node manually is recommended as a workaround for any problems with automatic install. You also have much better understanding of the things that happen if you do those things yourself.

The http://nodejs.org/dist/latest/ directory contains executables of the last version of Node.js engine (the engine only, i.e. without npm):

• 32bit version: http://nodejs.org/dist/latest/node.exe

• 64bit version: http://nodejs.org/dist/latest/x64/node.exe

The http://nodejs.org/dist/npm/ directory contains the latest .zip archive of npm (such as npm-1.1.16.zip when npm v1.1.16 was the latest).

Manual installation steps:

1. Make a clean directory and add that directory to your system's PATH variable.

2. Download the latest node.exe to that directory.

3. Download the latest npm's .zip file and unpack its contents to the same directory.

Then, with the usual help of PATH, you'll be able to run scripts (node scriptname.js) and install modules (npm install modulename) in any directory.

To update Node, download the latest http://nodejs.org/dist/latest/node.exe file and replace your old node.exe with it.

To update npm, run the npm update npm -g command.

The http://nodejs.org/dist/latest/ directory contains the latest .msi package (such as node-v0.6.15.msi when Node v0.6.15 was the latest) that you may use to install both Node.js engine and npm.

The http://nodejs.org/dist/latest/ directory contains the latest .pkg package (such as node-v0.6.15.pkg when Node v0.6.15 was the latest).

You can download the latest .pkg and run the installer and it will overwrite the existing version of Node currently installed.
