WARN install No prebuilt binaries found
in npm output. Such node is second mentioned kind.
This nodes need NPM package manager only. Install NPM via your distribution repository. For example:
apt-get install npm
for deb based distributions or:
dnf install npm (or yum install npm)
for rpm based distributions.
Now you can prepare desired node:
npm --global-style install NODE
where NODE is a node name as you can find it on www.npmjs.org.
Once it is finished you can see node_modules folder with desired node folder inside. Copy the node folder to the router via FTP/SFTP. Preferred target folder is /usr/lib/node_modules/node-red/nodes for Node-RED nodes and /usr/lib/node_modules for other nodes. It is a good idea to place files to /opt folder and create a link from the mentioned folders to avoid overriding while upgrading a firmware.
Nodes Using Other Languages
GYP package is NPM dependent on most distributions so you don't need to install it separately.
For most common languages C/C++, you can use same toolchains we use for building the router user modules. See Environment setup chapter in Developing User Modules Guideline to learn how to install it.
When you have installed all prerequisites, invoke following commands:
npm --arch=arm --global-style install NODE
and continue with copying as described above.
