Trying to learn angular recently, but I am stuck in an error of angular. So here it is.
I am using Ubuntu 18.04, installed node latest version via nvm.
But I have "two" nodes in Ubuntu,[default] nodejs which is v8 now, and the node v13.
When I try to create angular project with ng new my-first-project it runs good, but it keeps warning of some deprecated dependencies for example core-js. I upgraded core-js to the latest(forced using sudo). But the deprecation warning did not disappear, I thought to use sudo ng new my-first-project but this time it brings me error
You are running version v8.10.0 of Node.js, which is not supported by Angular CLI 8.0+.
The official Node.js version that is supported is 10.9 or greater.
Please visit https://nodejs.org/en/ to find instructions on how to update Node.js.
How can I change angular's using nodejs -> node?
You have two Node.js versions installed with nvm, v8 and v13. It seems that Node.js v8 is active, you can check this with node --version command line command. If the version is really v8 you have to change it with nvm to v13 using nvm use 13.{x.x} command. The {x.x} should be the concrete installed version. If you don't know the installed versions by heart you can check them with nvm list command line command.
If you change the active Node.js version to v13 with nvm it will be used by Angular CLI and you won't get the above mentioned error.

Im creating a new react project using create-react-app but it gives an error that says "You are running Node 12.13.0.
Create React App requires Node 14 or higher.
Please update your version of Node."
i have tried many things which i found in online articles but did not work.
try using NVM (node version manager) is a portable solution for managing multiple versions of node.
nvm install node
nvm use node
nvm install --lts
nvm use --lts
install and use to install the latest version and use it.
I am getting below error when I tried to use ng command
Node.js version v11.13.0 detected.
The Angular CLI requires a minimum Node.js version of either v10.13 or v12.0.
Please update your Node.js version or visit https://nodejs.org/ for additional instructions.
When I try to see the node version using node -v, I see node version on my machine is v12.18.3
So from where ng is getting v11.13.0? How do I resolve this issue?
I tried below steps
Clear the NPM cache
Uninstall both node versions from the NVM
Uninstall anything that starts with node in Control Panel\Programs and Features
Install required node versions in NVM
Install Angular CLI
and things started working for me.
Had the same issue. It turns out installed Angular CLI was not compatible with the installed node and npm version. I used the https://stackoverflow.com/a/60258560 to check the compatibility. Then performed following steps:
Uninstall Angular cli
Uninstall Node and NVM
Installed Node version I wanted (10.x).
Installed specific Angular version corresponding to Node v10 which was Angular Cli v11 at this time.
I was also facing the same issue in my Windows machine where the node -v version and the version picked up by ng command were different. This was because my node.js command prompt was picking the version from AppData\Roaming\npm folder. Cleaning up this folder fixed the issue for me.
Uninstall node
Empty the contents from C:\Users<user>\AppData\Roaming\npm
Install the required node version
when I do mvn compiling for flink source code，I get:
Node.js version v9.0.3 detected.
The Angular CLI requires a minimum Node.js version of eithor v10.13 or v12.0
when I input node -v, the result is 12.18
so,what's the comand to know the Node.js version in angular's eyes?
and where does the old version v9.0.3 come from?
I restart my computer and the error remains.
Thanks for your help.
(Python3.6) appleyuchi#Desktop:~$ which npm
/home/appleyuchi/.nvm/versions/node/v12.18.0/bin/npm
(Python3.6) appleyuchi#Desktop:~$ which nodejs
(Python3.6) appleyuchi#Desktop:~$ which node
/home/appleyuchi/.nvm/versions/node/v12.18.0/bin/node
I compile and get the following message again
Node.js version v10.9.0 detected.
what do you mean by angular's eyes? There is no different node for angular. if it is installed then the node is same for all framework.

You can use nvm if you want to work with multiple node versions
this link will help in using nvm
https://www.sitepoint.com/quick-tip-multiple-versions-node-nvm/
Installed the Angular CLI using this command
npm install -g #angular/cli
But when creating new project using command
ng new PROJECT-NAME
it shows
You are running version v8.0.0 of Node.js, which is not supported by
Angular CLI v6. The official Node.js version that is supported is
8.9 and greater. Please visit https://nodejs.org/en/ to find instructions on how to update Node.js.
But actually i am using nodejs v9.11.1
See screenshot of my cli
Mostly sounds like a version problem. The new angular cli version requires the latest version of node.
All you need to do is update node and npm to latest version , everything should work fine.
If you are working on windows I'd suggest just going on their site and getting the latest one(currently at the time of this post is 8.11.2). For linux based and mac I would suggest looking for a guide how to get latest version since installing from terminal with something like (apt-get install or yum) will not have latest version you need (can easily be changed with some simple commands)
Also do check the version of node with: node -v
There has also been a naming conflict on linux regarding node vs nodejs see this question.
I am trying to install the environment for react native.
I followed the instruction of the site until the point to enter into the cmd
create-react-native-app AwesomeProject
after several moments I get a big green message:
You are currently running Node v0.12.2.
React Native runs on Node 4.0 or newer. There are several ways to
upgrade Node.js depending on your preference.
nvm: nvm install node && nvm alias default node
Homebrew: brew unlink iojs; brew install node
Installer: download the Mac .pkg from https://nodejs.org/

I try to upgrade my nodejs but I have the newest version form the site.
why does it still throws me this error ?
Hi user24136 i build react native apps myself and i have latest Node version running. Error states your Node.js installed is old and React Native does run on Node 4.0+. Seems like your on a Mac, visit this link Node.js and use installer to upgrade your NPM and Node to latest versions. After successful installations run commands node -v and npm -v and you should see newer version v6.10.3 and 3.10.10 respectively. Then run command react-native init AwesomeProject and check if it works.
This problem interested in from your only node version
you can use sudo n stable command your terminal. This command increase your node version.
