Install
-------
## Install
This node is usually installed by default in Node-RED so should not need to be installed manually.
This node is sometimes installed by default in Node-RED so may not need to be installed manually.
Run the following command in your Node-RED user directory (typically `~/.node-red`):
npm i node-red-node-serialport
For versions on node.js prior to 4.x (ie v0.10.x and v0.12.x) please install using
sudo npm i -g npm@2.x
npm i node-red-node-serialport
You may also have to install or upgrade GCC to be version 4.8 or better.
Alternatively you can simply install the older version of this node.
npm install node-red-node-serialport@0.0.5
During install there may be multiple messages about optional compilation.
These may look like failures... as they report as failure to compile errors -
but often are warnings and the node will continue to install and, assuming nothing else
failed, you should be able to use it. Occasionally some platforms *will* require
you to install the full set of tools in order to compile the underlying package.
Usage
