Solution 1 (Recommended)
I suggest that to use a tool for switching versions of node and npm called nvm. By the way, you don't have to upgrade/downgrade whole project dependencies. It is a minimal solution and it will work on further projects.
To install nvm check the table of contents section in here.
After installation of nvm:
Step 1
Installing desired node version
nvm install v14.18.0
Also you can check supported versions by this command
nvm ls-remote
Step2
Switching version
nvm use v14.18.0
Step 3
npm install
Solution 2
It is more painful because you must repeat each project's steps.
Downgrade your node version to "14.x.x"
Delete the package-lock.json (because you installed it for the new version of the node)
And install dependencies.
And repeat these steps for different versioned projects.

Any suggestions what I am doing wrong?
I appreciate your replies!

Your problem lies in using multiple conflicting versions of autoprefixer. Those come from different packages, for instance react-scripts. I noticed that, while your react is pretty up-to-date, your react-scripts are two major versions behind (3.2.0 vs. 5.0.1). This means there have been two times breaking changes in between, which could easily explain the conflict. If you aren't sure what that means, head over to Semver for an explanation.
I can't possibly tell if this is going to resolve the problem, but I would make a quick copy of the project, remove all dependencies from package.json and run npm i babel-eslint react react-dom react-router react-scripts web3. There are more sophisticated ways to do this, but this would quickly tell you, if updating all packages fixes the problem.

'node' is not recognized as an internal or external command, operable program or batch file

I'm running "npm install node-sass" from git-bash-cli in Windows 10 and getting a "'node' is not recognized as an internal or external command,
operable program or batch file." error.
I have been using this setup for years and the issues started when I upgraded node to 10.16.0
To prevent unnecessary replies:
All the questions I have seen simply say to add the path variable.
I have added Node to the PATH variable and tried a number of different ways of writing it. I ended up reinstalling Node.js and that does it automatically, so I just left it as that.
node runs from the command line, just not from scripts, like scripts in the package.json file.
I have tried reinstalling node 8.11.3, which is the version I was using before the problems started, but I get the same error. I am back to v 10.16.0 again.
Error code is as follows:
> node-sass#4.12.0 install C:\projects\true\true\website\truevue\node_modules\node-sass
> node scripts/install.js
'node' is not recognized as an internal or external command,

Thanks all who helped, hope this can help someone else

I think you must add the path of node.js to the system variable
First: open Control Panel -> System and Security -> System -> Advanced System Settings -> Environment Variables
Second: in "User variables" or "System variables" find variable PATH and add node.js folder path as value.it is C:\Program Files\nodejs;If it doesn't exists, create it.
Third: Restart your computer.

Is this a permissions issue? Or is there something wrong with the way npm is set up? Any help would be appreciated.

Try recreating package.json for that repo with npm init . command and go through all the steps.
Remember having correct repository link in the repository section.
I had the same problem but above helped.

Problem 1: The repo on your post does not exist.
You might've used the wrong repo url.
Use the correct repo url: https://github.com/akveo/ng2-smart-table
Problem 2: The repo does not have a version specified in the package.json
Just fork it and add a version in the package.json file.
Or, use the npm version,
npm install --save ng2-smart-table

npm install -g . doesn't copy, fails

The npm developer docs say to make sure your package installs globally before publishing by running npm install -g .. I'm trying to build an ES6 CLI package that can be installed and run globally, but after running Babel to transpile it (with the es2015 plugin), the global install on my machine fails.
I've created a simple demo ES6 project that reproduces the error. Cloning and running npm install -g . throws the error in the README:
$ npm install -g .

Am I doing something wrong? I've tried a few different commands, with both Babel and NPM, but ultimately nothing seems to get copied into /usr/local/lib/node_modules.

The "bin" property of the package.json points to an app.js file in es5/bin but there is no app.js file. You'll need to point it to the csp.js file:
package.json
"bin": {
"csp": "es5/bin/csp.js"
},
