Environment variables + node.js

5olar · April 16, 2019 at 3:00 PM

I'm trying to install and create environment variables for node.js.

I know it can be installed via docker, but not sure how I would create environment variables for a docker container, so I tried running manually.

I've unpacked node.js (linux / arm64) and used the export command in bash:

Code

export NODEJS_HOME=/storage/nodejs/node-v10.15.3-linux-arm64
export PATH=$PATH:$NODEJS_HOME/bin
echo `node -v`

This doesn't work even within the same bash script; it says node can't be found.

I'm a complete newb, sorry if the solution is obvious... thanks for any help.

Do you even have folder /storage/nodejs/node-v10.15.3-linux-arm64 ? Because what you wrote is correct and should work - at least it does here:

Code

LibreELEC:~/nodejs # node -v
v10.15.3

The folder does exist. If it's relevant, I'm using a custom build for Amlogic S912 by kszaq.

I tried a fresh OS install and the problem still exists. If there's a way to set environment variables for global use (not just ssh session or bash script) I could test that?

This doesn't work even within the same bash script; it says node can't be found.

What is the exact error?

And isn't S912 just arm (32 bit)?

Silly me, thought it was 64 bit. The error was "-sh: node: not found" so assumed I was doing something wrong, but it works with 32 bit.

That aside, how can I set environment variables without them resetting after reboot or closing ssh session?

Create file /storage/.kodi/addons/http://node.js/profile.d/node.js.profile and put both export variables NODEJS_HOME and PATH inside.

Tried that and NODEJS_HOME is set, but PATH isn't. Is PATH being overwritten by something else?

node.js.profile:

Code

export NODEJS_HOME=/storage/nodejs/node-v10.15.3-linux-armv6l
export PATH=$PATH:$NODEJS_HOME/bin

PATH stays as:

Code

export PATH='/usr/bin:/usr/sbin:/storage/.kodi/addons/service.system.docker/bin'

True, PATH can't be set here because it is overwritten later.

But bin folder from addon is automatically add to it. So move everything under /storage/.kodi/addons/node.js folder.

My all commands to make it happen:

Code

mkdir -p /storage/.kodi/addons/node.js/profile.d
cd /storage/.kodi/addons/node.js
echo "export NODEJS_HOME=/storage/.kodi/addons/node.js" >profile.d/node.js.profile
wget https://nodejs.org/dist/v10.15.3/node-v10.15.3-linux-armv6l.tar.xz
tar --strip-components=1 -xf node-v10.15.3-linux-armv6l.tar.xz
rm node-v10.15.3-linux-armv6l.tar.xz

# exit terminal and login again

LibreELEC:~ # node -v
v10.15.3

LibreELEC:~ # ls -al $NODEJS_HOME

Really useful, thanks for your help. Also, not sure why I did an OS wipe before checking if my processor is 64 bit, haha.
