NPM get prefix issues - node.js

I am having issues with the npm. (on MAC)
I installed node and npm normally, but couldn't run:
$npm install -g angular-cli
it says unhandled rejection error, EACCESS: ...
and none of the solutions I found on the web couldn't help me.
I tried to reinstall node and npm multiple times, didn't help.
Then I tried to make an ionic project through the terminal, unsuccessfully. Similar issue EACCESS: permission denied...
And now I kind of messed up something with:
$npm config get prefix and $npm config set prefix
whenever I try to run some npm command I get a bunch of lines:
Eaccess, cannot read property, etc...
Does anybody know how can I solve this?
Is there a way to completely remove nodejs and npm and then to install it from scratch.
The traditional way and using homebrew didn't help me.

Try: nvm uninstall {version of node you are using}
To get the version do: npm -version

Error: Can't update or reinstall my node modules

I recently updated my Node and now whenever I try to update the node modules of this project I get errors. This is the only project that gives issues with it, all the other once are fine.
I tried removing the node module's and the react-countdown-clock in the package.json, I also tried copying the files to see if i could find the problem. But with everything I tried I still got the error's. So I was wondering if anyone has any advice for me how to fix it.
Execute below Commands
npm install -g npm-check-updates
ncu -u
npm install
npm start

Check if you have npm install by typing npm --version
If you don't have npm follow this link to download Node.js to your computer. https://nodejs.org/en/download/

can't update npm (missing access)

Breaking my head to get over that error. I've tried every forum but still I can't find a proper solution. I also uninstalled and reinstall npm and still same issue.
Please save me!
npm error

Just a wild guess:
remove .npm-modules in your home folder
remove modules from the project you are using
npm install, all should be fine
Use homebrew to install npm and nodejs. Write the command as shown below:
brew install node . Once it is successfully installed check it with node -v.

Can install but can't run npm packages

I'm having trouble with my node.js/npm setup,
I freshly installed it via the website and it worked fine.
It told me to make sure /usr/local/bin/npm has to be in my path and when I run
echo $PATH it is in there, so it should be fine.
I can now install packages (tested with npm i webpack -save-dev) the installation works as expected, without any errors.
But when i run webpack all It is giving back is command not found has anyone experienced
something like this before?
I believe what you are looking for is a global package install.
Try using
npm i -g webpack
You can get help on install with
npm help i
Did you install node v8/npm v5?
In that case, it seems there's an open big-bug ticket on the npm repository.
