I found out that if you have installed nvm to manage different node versions, is showing one version but using another from behind, I also have problems with my global brew node installation, so I had reinstalled again from scratch. As a general tip, unload the nvm and work with the npm global installation.
Update your nodejs should fix
sudo npm cache clean -f (force) clear you npm cache
sudo npm install -g n install "n" (this might take a while)
sudo n stable upgrade to lastest version
I checked the file "/usr/lib/node_modules/react-native/local-cli/server/checkNodeVersion.js:43" and found that "React Native runs on Node 8.0 or newer."
But my node vesion was 6.0 ,so that the problem.
The error belongs with node js version.
node --v in cmd will show version less than 8.
Update your node version by installing nvm. This will help you update version.
https://stackoverflow.com/a/7718438/9090200
In-case you are using nvm to install a new version of node.
It's important that you will use nvm alias default node so it will be the default version while opening new shells.
React Native runs on Node 8.0 or newer
If you are using nvm then set "nvm alias default >=8.X.X" like "nvm alias default 8.0.0"
Re-open your terminal and try it again.

When I run npx create-react-app, I had these errors. Maybe someone knows whats it's wrong? P.S. also had tried npm-install -g create-react-app.

This seems to be a recent problem with npm. There is an issue open as of the last few hours and it seems like people are working on it. I don't think it's anything to do with yourproject.
The issue
While the issue is being fixed: try installing node version 12.12.0 as shown below (if using nvm) and run create-react-app again.
nvm install 12.12.0
nvm use 12.12.0
I'd try to clear your cache npm cache clean --force. What version of node and npm are you using?
I updated my node version from 10.16.3 to 12.14.0.
3 months ago, I made api by using node js. At that time, it worked well.
But now it throws errors.
These are what I did and errors.

Please help me
I have found is to just use the nodejs.org site
1. go to https://nodejs.org/en/download/releases/
2. find version you want and click download
3. click the .pkg executable and follow the installation instructions
One way is to use NVM, the Node Version Manager.
You can find it at https://github.com/creationix/nvm
It allows you to easily install and manage multiple versions of node. Here's a snippet from the help:
Usage:
nvm install <version> Download and install a <version>
nvm use <version> Modify PATH to use <version>
nvm ls List versions (installed versions are blue)
You can use nvm to select your preferred node version with ease.
Check this repo for details: https://github.com/nvm-sh/nvm
I found it!
Before I did do like this.
npm install
node server
But I couldn't run it.
I try many times to fix, and finally I found this!
npm install canvas or yarn add canvas
And now it works!
:D
I am trying to use the Aurelia-cli tool to create a new Aurelia project. I am using a Windows 10 machine with node and git installed.
I created a new empty folder for the project, and opened a command prompt and navigated to this folder.
I then ran the following command which completed successfully:
npm install -g aurelia-cli
Then I ran the following to create a new project:
au new
But this gave the following error:
C:\Users\xxxx\AppData\Roaming\npm\node_modules\aurelia-cli\bin\aurelia- cli.js:3
const resolve = require('../lib/resolve');
^^^^^
SyntaxError: Use of const in strict mode.

Any ideas as to what would be causing this?
Make sure you have a compatible version of Node installed. You can check the your Node version with node -v.
Aurelia CLI is only compatible with Node >= 4.x
You can download a compatible version of Node from here.
This error was to do with the node version but it was not a process of simply downloading and installing the latest version. I got this working after going through the following steps:
Open the Node command prompt and upgrade the node version with:
npm cache clean
npm update -g
Still in the Node command prompt, go to the relevant directory and run
au new
And it worked fine.
Even after upgrading the node version as above, the version had not changed in the normal windows command prompt and the aurelia cli command still did not work from there. So this problem seems to be to do with node versions, windows, and my setup, rather than with the aurelia cli.
Hello I receive the following message when trying to install npm. I downloaded the most recent node.js but it doesn't seem to download npm. I keep getting the belowenter code here error message after deleting node.js and reinstalling it.
When I try installing node.js I don't see the following being created:

This is the first time installing node.js. I just installed it on my old computer and it worked out fine. I am new to this so so your patience is much appreciated! Thanks!

Due to the bug in versions this is what i did -
I have faced the same issue in my Windows 10 PC. After looking into solutions, since i couldn't find the exact solution for the issue i was facing
Cannot find module 'npmlog'
I just uninstalled the node js and then, deleted both 'npm' and 'npm-cache' in
"C:\Users\YourPCName\AppData\Roaming"
Then, i downloaded the latest version of node from Node JS Website
And, installed node js
After that i checked with the path in environment variables.
Finally run the command prompt 'run as administrator' and npm install npm -g
Checking your version will show the latest version. 'npm -v'
I got the latest version - v3.10.9
Try this. this should work.
Install a newer version, it's been a bug in previous version.
I've uninstalled and reinstalled yo and download using npm. And switched to node 10.28 and node 11.14 but when I try and run a yo generator I keep getting:

I tried uninstalling / re-installing npm, yeoman, node, and the generator, plus googling and trying random things - nothing seemed to help.
Solution:
After some time fiddling - this fixed it:
cd /usr/local/share/npm/lib/
npm i download && npm update
Reinstall the latest version?
I don't know what went wrong here, but a module is missing. It might be because of the way you're changing the node version (it might change the path to node modules). Or it might be an installation error, make sure to read through the npm install logs.
I had this same problem on a version of node that I installed with brew and then upgraded (several months later) using brew upgrade node. I fixed it by running brew uninstall --force node to remove all the versions of node and then running brew install node and npm install -g yo generator-kraken bower grunt-cli again. This may have happened as a result of having multiple versions of node installed, as reported by brew when I attempted to unistall node the first time (output below).
brew uninstall node
Uninstalling /usr/local/Cellar/node/4.2.1... (2738 files, 36M)
node 0.10.29 is still installed.
Remove them all with `brew uninstall --force node`.
"npm i download" never worked for me at all. With "npm install -g download" I solved definitely my problem followed, as suggested, by "npm update".
