Starting a new project using
npx create-react-app my-app --typescript
I had no errors, I installed
npm install --save react-router-dom #types/react-router-dom
And get the error
mixin-deep#2.0.1 added 1 package from 1 contributor, updated 1
package, moved 1 package and audited 902212 packages in 13.484s found
12969 high severity vulnerabilities
I'm running Node v12.6.0 & npm 6.10.1 on a Windows PC. I've tried running npm audit fix, but it states I have to fix them manually.
Installing react-router and getting 12969 high severity vulnerabilities seems a little excessive, does anyone know what's going on? Am I doing something wrong?

create-react-app is no longer working on my computer
A template was not provided. This is likely because you're using an outdated version of create-react-app.
Please note that global installs of create-react-app are no longer supported.
You can fix this by running npm uninstall -g create-react-app or yarn global remove create-react-app before using create-react-app again
I obviously try the npm uninstall -g create-react-app command, but it didn't work.
I tried to update npx, npm, clear cache on npx, on npm, I tried installing the latest version of the create-react-app. nothing worked so far.
npm install create-react-app#latest

I tried uninstalling tar, the exact same message as before appears.
I solved it
the command npm install tar#6 -g
was what I needed to properly update tar and the error disapear.
Thanks to all who took the time to help me

There might be a problem with the project dependency tree.
It is likely not a bug in Create React App, but something you need to fix locally.
The react-scripts package provided by Create React App requires a dependency:
"eslint": "^7.11.0"
Don't try to install it manually: your package manager does it automatically.
However, a different version of eslint was detected higher up in the tree:
/Users/sujit_jaiwaliya/node_modules/eslint (version: 6.8.0)
SOLUTION:
This worked for me I hope it does the same to you guys:
I Unistall eslint version 6.8.0 :
npm uninstall eslint#6.8.0
Then I install eslint#7.11.0:
npm i eslint#7.11.0
Then i run fix audit:
npm audit fix --force
Then i changed the DIR file by adding a .env file with this code in it :
ESLINT_NO_DEV_ERRORS=true
This issue has been fixed in the react-scipts:"4.0.3" but, the eslint errors present in the project are not converted to warnings by default. You have to create an .env file that should contain a ESLINT_NO_DEV_ERRORS=true flag. Due to this flag, you will receive the eslint errors as warnings and not as errors in the development.
This flag is ignored during production and when they are any git hooks running, which will, in turn, cause an error when you are trying to commit the code with an eslint error in it.
This is because you already have some other version of eslint installed. To resolve this, first remove that version (in this case 6.8.0) and then again run
npm start
Uninstall the other version using npm uninstall eslint
I started the project with the right versions of everything but somewhere my code broke and started requesting a different version of eslint. "react-scripts" was the only package that had eslint as a dependency.
I tried npm uninstall eslint but it didn't quite work. So I removed react-scripts and then reinstalled it as below
npm uninstall react-scripts
npm install react-scripts.
You might want to install the specific version that was installed before. If your current version is 4.0.3 then when installing just add it at the end like this npm install react-scripts#4.0.3 on step 2 above.
It totally removed the error for me, hope it does for you too.

I have been trying to start learning React and JSX but I have been running into problems with using create-react-app. Every time I have used it eventually states that it is aborting installation and that npm install --save save-exact --loglevel error react react-dom react-scripts has failed. It also state before the installation aborts that there were a number of packages added and a certain number of vulnerabilities found. I have tried searching for other ways to create a React app from scratch and have followed these tutorials to only run into problems and have these fail as well.
Node Version 10.15.2 -- Same error occurred.
Reverted to Node Version 8.15.1 -- Same error still occurs.
NPM version 5.8.0 has not been changed.
npm cache clean --force
Has not changed receiving the error.
If someone could shed some light on what I might try next or what additional information might be helpful I would greatly appreciate it. Thank you. Here is what my screen looks like after trying npx create-react-app my-app
