Create React App with an older version of node

I am trying to use Create React App but getting an error that it requires Node 10 or higher. My node version is Node 8.10.0 and there's no way for me to update the Node version since it's a work machine. Is there any way to run an older version of Create React App to work with my older Node version?

I managed to run it. It seems like the last versions of the packages which support Node 8.x.x are 3.4.1 for create-react-app and 3.1.1 for react-scripts. What I did:
npm uninstall -g create-react-app
npm install -g create-react-app#3.4.1
create-react-app my-app --scripts-version 3.1.1
But it's better to update your Node version to the actual (or LTS at least).

From my understanding you can add the flag --scripts-version to your npx create-react-app command. So for example if you wanted to run react version 15.6 you would run something like:
npx create-react-app appname --scripts-version 1.0.14
You can reference the react-script repo as well as the NPM Package for more information on which version of the script you would want to run. Hopefully this helped! If not please let me know and I'm more than willing to try and look more into it.
Edit:
Forgot to mention that you need to make sure to change the versions of react and react dom within your package.json after. So after installing you would run:
npm i react#15.6
npm i react-dom#15.6

Angular project creation failed because of deprecated circular-json

I used following command to create new angular project
ng new hello-world
It failed showing
npm WARN deprecated circular-json#0.5.9: CircularJSON is in maintenance only, flatted is its successor.
npm ERR! Unexpected end of JSON input while parsing near '...rocess":"~0.7.0"},"_h'
Then I installed flatted using...
npm i flatted
But the error still occurs.
How to use flatted instead of deprecated library circular-json?

Run following commands that will clean NPM cache
npm cache clean --force
after this run following command
npm install -g #angular/cli#latest
then you can create angular project.

If it doesn't work, even after clearing the cache, which happened in my case:
Make sure you try the ng new create-app command using Powershell in administrator mode.
This worked for me.

I had the same problem. None of the above mentioned answers worked for me.
So I removed the content of .npmrc, ran the generate command and it worked.
After that, you can restore the content of your .npmrc if needed.

ionic building TypeError: env.runcmd is not a function

During build of an ionic App, this error is shown:
anyone can help me ?

It says:
Error occurred during command execution from a CLI plugin
(#ionic/cli-plugin-cordova). Your plugins may be out of
date.
Did you try to install latest cordova plug-in :
$> npm install #ionic/cli-plugin-cordova#latest
Also update the dependencies....

Things to try:
run "cordova platform add ios" and "cordova platform add android"
run npm install --save --save-exact ionic#3.6.0 and then upgrade it to newest version
if it still does not work then just do downgrade without upgrade and wait until stable version will be released

In my case, I just change version package.json of this two plugins under devDependencies section. (In your case version number may differ)
"#ionic/cli-plugin-cordova" : "1.4.1",
"#ionic/cli-plugin-ionic-angular" : "1.3.2"
after this change in package.json run below command:
npm update
Now try to build, it's working.

The main problem for me was the #ionic/cli-plugin-cordova , so I downgraded it to v1.4.1 ( Don't know if any of the later versions are working fine.)
Command:
npm install --save-dev #ionic/cli-plugin-cordova#1.4.1

I my case what I did was went to the project folder and ran the following command to Get it working
cd platforms/ios/cordova && npm install ios-sim#latest

Error: Module did not self-register.

Server: Ubuntu server 14.04
Node: v4.2.6 LTS
npm: 1.3.10
I pullled my colleage's work from git remote. He made the node_modules as .gitignore. So I have to npm install the modules.
But after a successful install of npm. when I try to start the project using mocha. It remind me of a module didn't self-register
The error comes from the module of Bcrypt.
at bindings (/base_dir/node_modules/bcrypt/node_modules/bindings/bindings.js:76:44)
I don't want to downgrade my node to 0.10, because, I can't use JS promise in that version. Somehow, JS promise is a must in my work

This problem happens mostly because you copied/cloned the repository from somewhere else, but some modules for nodeJS should be installed/registered locally on your machine, during which the happens the build process(maybe some native language like C).
and be noted that the node_modules folder should not be staged for versioning. and should be ignored by versioning tool. and the one who is trying to clone this package should build / install firstly.
I find the answer to this problem.
But plz don't devoted this just because you want.
I upgrade the NPM using
npm install npm -g.
after that, delete the node_modules folder,
then,
npm install
Everything will be good.

I had this issue while setting up my Cypress project.
After trying to delete and then reinstalling all the node-modules and upgrading everything I found out the issue was caused because Cypress uses node from its bundle version by default (which was version 8.0 in my case) , whilst the package I wanted to use required the node version to be 10 or higher.
I did have node 12.0 installed on my machine but since cypress was not using that I had to add the line shown below in the settings file (cypress.json) to set the value for 'nodeVersion' to 'system', this way you are telling cypress explicitly to use the node version installed on your machine.
Add this line to your settings file:
**"nodeVersion": "system"**

How to fix npm peer dependency issue?

I have a package.json that has the following modules that are conflicting:
react-router which needs react 0.13.x
redbox-react which needs react#>=0.13.2 || ^0.14.0-rc1
I just did an npm install react and it installed react#0.14
I am trying to install react-bootstrap which needs react#>=0.14.0.
I have been a few solutions:
delete node_modules from all the node_modules of dependencies every time I update
delete and reinstall all modules every time you face an issue
upgrade to npm 3.x which is still pre-release and
What is a good way of fixing these issues without having to do 1 or 2 which is npm version agnostic.
P.S.: All the modules referred to here have been installed locally.

Ensure you have the latest version of react-router (currently 1.0.0-rc3).
The react module is only listed as a dev dependency, and the requested version is 0.14.0 so there shouldn't be any issues.
