Basically, I installed n(tj/n)for managing my node versions, and after that I installed a node version 14.6, it automatically switched my node version to 14.6 and also try to switch my version using n command but that shows only the one that I installed with n.
So, is there any way to switch to my main node version (that's installed previously) ??
I don't know if n preserves your current node version, but if you know your previous version e.g. 12.13.0 just type
n 12.13.0
It will install and switch to 12.13.0. After the installation you can switch versions just running n.

I want to host my node api (built in node version 12.16.0) on cPanel, but available version for node in cPanel is 12.9.0 (Most recent). What should I do now ? Does it really matter, the node version ?
Although 12.18.2 is LTS on the current date, but I think you can move ahead with 12.9 as well. It is a minor update.
In case you want to manage the version then you should use nvm node version manager. Using nvm you can manage the latest version as default on your server.
Make sure to install the latest version of Node Js before setting that as default version on your server. and you need to install nvm as well.
Use the following commands:
nvm install 12.18.2
nvm alias default v12.18.2
I'm trying to install node version 8 (node#8) on my mac through homebrew.
My current version of node is 13.6.0, which I downloaded through homebrew, and I'd like to be able to switch between node 8 and node 13 versions for different projects.
However, when I try to download node#8 using
brew info node#8
I get the following error
Error: No available formula with the name "node#8"
To diagnose why, I ran
brew search node
And I was shown the following
libbitcoin-node node ✔ node-sass node#12 nodebrew nodenv
llnode node-build node#10 node_exporter nodeenv
It looks like my current version of node can't even search for #8. That being the case, I'd like to know two things.
What is the best homebrew (or otherwise) command sequence to get node8 on my machine, given my version of homebrew can't find node8 using brew search?
What sequence should I use to switch between the node 8 and node 13 versions on a project by project basis?
Use NVM - Node Version Manager
https://github.com/nvm-sh/nvm
You can set your default Node version and install any other versions you like.
Switching off your default version is as easy as nvm use 10.12.0 or whatever version you wish.
I have been using n for a long time now. Dead simple. To install node 8 just type:
$ n 8
https://www.npmjs.com/package/n
I download Node 10.11 a few weeks back and I have a repo that requires me to have the LTS version of Node of 8.12 at the time of this question. if I download the LTS will that mess up the install I have already or will it overwrite it? I'm using a Mac with High Sierra Also without using NVM
You can use nvm and have multiple versions of node on the same machine and switch by doing "nvm use version".
I can't comment yet, but to answer your question posed to Giorgos...
"So can I install NVM without uninstalling the version of Node I have already on my mac? "
Correct. NVM allows you to install whatever versions of Node you want and switch between them whenever you want. You can also set it so certain projects run a specific Node version so you don't have to worry about switching between versions if you are jumping between projects.
This allows you to have old versions, say 0.12 for random things, but also have Node8.x.x for your one project, and Node 10.x.x for another. It is incredibly useful, and if you ever need to verify compatibility with a new version, you can install the Node version via NVM and run your tests/project with that version of node. If it works, you can stick with it, if not you can switch back and look into updating your code to work with a new version.
With nvm tool one can execute nvm use 6 to select the latest installed node.js v6. How would I do the same using the n CLI tool?
The command(s) will be executed on the CI.
n 6 will install (activate) the newest version of node 6.
You can specify partial version numbers with n it will use the newest matching version.
One simple way we can achieve it,
n ls Output the versions of node available
Select the one which you need and install by generally by regular n method ?
n <version> Install node <version>
I'm trying to install node.js on a friend's computer. We had an old version (0.4.*), then installed n to update to a more recent version of node using n - node version manager
now instead of having an old version of node, we get
$ node -v
Segmentation fault
$ n --version
1.2.1
$ npm --version
Segmentation fault
When we type n the versions we installed show up but they are all greyed out. What's a Segmentation fault, why is it happening and how can we fix it?
Unless you're using something with binary dependencies (npm doesn't), segmentation fault means on of two things:
there is a bug in node.js core, and it should be reported
your node.js installation is broken
So you can solve this by reinstalling the most recent node.js version using a standard way from nodejs.org website. If it still segfaults (highly unlikely, but possible in some non-standard environments), report it to node.js core team.
