How to install node.js v16 on VPS cPanel WHM when ea-nodejs10 installs v10.24.1?
I want to yum install xrpl to sign transactions via the xrpl.js library on a cPanel WHM VPS and have made it through How to install a Node.js Application enough that all four ea-*** RPMs, including ea-nodejs10 v10.24.1, have been installed. However, xrpl.js recommends node.js v14 while also supporting v12 & v16.
Further, package-lock.json must be installed prior to xrpl.js - yet even though WHM Edit Package shows package-lock.json added:
yum install package-lock.json throws "No package package-lock.json available." Although repeating yum install ea-nodejs10 returns "Package already installed."
So I would appreciate advice on how to install node.js v14 and package-lock.json on this system thanks.
I am now able to sign, send, and validate XRP Ledger transactions with python - hence my iOS-XRPL UI javascript brew will delegate its signing-validating to python functions.
Edit: MobileApp-XRP Ledger blockchain Linux dedicated server xrpl-py library installation
MobileApp business XRPL transactions on MoblieAppDomainName.com browser requires a Dedicated Server, instead of a VPS, to install the required xrpl-py python library. Several guides continue to evolve for the several systems.
Present solution starts with Bluehost Linux DS Python Installation latest version 3.9.2 guide.
However the make install command attempts - and fails - to break the existing python 2.7 installation integral to the cPanel framework and needs to be replaced by make altinstall as described by Grepitout: How to Install Python 3 in cPanel Server.
Except that didn't quite work either -> What eventually worked on author's Mac OS-Linux system was Computing for Geeks: Install Python 3.9 on CentOS 8 / CentOS 7 guide:
$ ssh username@serveripaddress
sudo yum -y update
sudo yum groupinstall "Development Tools" -y
sudo yum install openssl-devel libffi-devel bzip2-devel -y
$ gcc --version
sudo yum install wget -y
wget https://www.python.org/ftp/python/3.9.7/Python-3.9.7.tgz
tar xvf Python-3.9.7.tgz
cd Python-3.9*/
./configure --enable-optimizations
sudo make altinstall
$ python3.9 --version
