[Raspberry Pi] install the node environment and Raspberry Pi node Environment

This article is not about node compilation and installation. It is said that it takes a long time, so at first I refused. This article shows how to deploy ndoe compiled execution files.

The download directory on the node official website contains the compiled execution files for arm. Address here: https://nodejs.org/dist/v4.2.1/

Select an appropriate version

Uname-

To display system information

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

Tar xvzf node-v4.2.1-linux-armv7l.tar.gzMobile

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

Configuration

To make the node and npm commands effective in all directories, you must either create a connection between node and npm in the existing PATH, or add the PATH of node and npm to the PATH. I selected the link scheme.

Node connection

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

Npm Link

Npm in the node-v4.2.1-linux-armv71/bin directory is soft chain by default to node-v4.2.1-linux-armv71/lib/node_modules/npm/bin/npm-cli.js due to load path and current working directory problems, there will be problems with direct hard chain or soft chain, two in the node-v4.2.1-linux-armv71/lib/node_modules/npm/bin/directory there is a bash script named npm, just link this npm.

sudo ln -s /usr/local/bin/node-v4.2.1-linux-armv71/lib/node_modules/npm/bin/npm /usr/local/bin/npm

An error occurred while trying npm-v. It indicates that the npmlog module could not be found and the working directory was faulty.

Open the script and find that the script is qualified for a slight transformation.

Paste the modified file content:

#!/bin/sh(set -o igncr) 2>/dev/null && set -o igncr; # cygwin encoding fixbasedir=$(dirname `readlink -f $0`)cd $basedircase `uname` in    *CYGWIN*) basedir=`cygpath -w "$basedir"`;;esacNODE_EXE="$basedir/node.exe"if !
