[Raspberry Pi] Install node environment

This article is not a compiled installation of node, it is said to take a long time, so at first I was rejected. This article shows how to deploy the compiled execution file for Ndoe.

Node's official Web download directory itself has compiled executable files for arm. Address is here: HTTPS://NODEJS.ORG/DIST/V4.2.1/

Choose the right version

Download the appropriate version for the Raspberry Pi, the appropriate version of the choice is this: SSH login on the Raspberry Pi, the console will display the relevant information:

See the 4th line above the text (blank line ignored) The last word has no armv71, perfect match.

If you have a direct Raspberry Pi on the display device, then you can also enter it through the terminal window

uname -A

To display System Information

You can also find the relevant system architecture information ARMV71

Selected version of the information I can only provide such two, in addition, my hardware is Raspberry Pi 2 generation B type (E14), if the same hardware, directly select the ARMV71 version of the good, good choice of version, you can download.

Download

HTTPS://nodejs.org/dist/v4.2.1/node-v4.2.1-linux-armv7l.tar.gz

Or you could use your PC to get a good, sftp, Raspberry Pi.

Extract

tar xvzf node-v4. 2.1-linux-armv7l. tar. gz

Move

MV node-v4. 2.1-linux-armv7l/usr/local/bin

Configuration

To make the node and NPM commands available in all directories, either create a link to node and NPM in the existing path path, or add the path to node and NPM in path. I chose the link scheme.

Node link

sudo Ln /usr/local/bin/node-v4. 2.1-linux-armv71/bin/node/usr/local/bin/node

NPM Links

The NPM in the Node-v4.2.1-linux-armv71/bin directory is the default for soft links to node-v4.2.1-linux-armv71/lib/node_modules/npm/bin/ Npm-cli.js due to loading path and current working directory problems, direct hard chain or soft chain will have problems, two in node-v4.2.1-linux-armv71/lib/node_modules/npm/bin/ The directory also has a bash script called NPM, which is linked to NPM.

sudo Ln -s/usr/local/bin/node-v4. 2.1-LINUX-ARMV71/LIB/NODE_MODULES/NPM/BIN/NPM/USR/LOCAL/BIN/NPM

Try to npm-v found an error, said to be unable to find the Npmlog module, but also the working directory problem.

Open this script and find that the script can be qualified for a minor makeover.

Post the modified file content:

#!/bin/SH(Set-O igncr)2>/dev/NULL&& Set-o igncr; # Cygwin encoding Fixbasedir=$(dirname`Readlink-F $0') CD $basedir Case`uname`inch*cygwin*) basedir= ' Cygpath-W "$basedir"`;;EsacNode_exe="$basedir/node.exe"if!
