I just installed Ionic with
npm install -g #ionic/cli
When I try to run
ionic start ionic-test-app
the initialization fails with a npm dependency error.
Something about a wrong version of a package called postcss.
$ ionic start ionic-test-app

I am fairly new to npm and I can't seem to find a solution on this site or anywhere else on the internet.
I have tried both the --force and --legacy-peer-deps, but received the same error.
What is the reason for this error and how do I fix it?
My node, npm & ionic versions are:
$ node --version
v16.2.0
$ npm --version
7.13.0
$ ionic --version
6.16.1
That was my first guess - installing a more recent version of postcss, but unfortunately that did not solve it for me. Solution was downgrading from npm's version 7 to version 6.
npm install -g npm#6
For some reason I couldn't get it to work on node version 16.2.0.
However, using node version manager nvm I installed a second instance of node, the LTS version 14.17.0.
With this downgrade, the setup process works.
nvm install 14.17.0
I ran into this error and manually installing postcss npm i postcss fixed it as the stack trace shows a dependency was relying on the latest version of postcss version 8.2.15 and what was found was version 8.2.14.
Had a similar issue with node start using npm v7.5.2 and was fixed by upgrading to v7.22.0.

I just updated all my node modules using npm-check-updates.
I did this so I could install the latest version ngx-stripe, which needed some updated node modules that I didn't have installed.
After updating all my node modules and then trying to install ngx-stripe I got this error below, showing me that ngx-gallery-9#1.0.6 has a peer dependency of tslib 1.10.0, which is true, but my installed version is tslib 2.5.0 in node modules.
QUESTION - Should I use --force or --legacy-peer-deps when running the npm install for ngx-stripe or is there something else I should try first like updating the tslib peer dependency for ngx-gallery-9?
Here is what I see:

➜ client git:(master) ✗
Your problem is completely unrelated to ngx-stripe, but whenever you run npm install, NPM tries to fix all of its dependencies in package.json at the same time, and because you have a problem with ngx-gallery-9, all npm installs are failing. You can ignore the error for now, using --legacy-peer-deps, which will tell NPM to not try to deal with peer dependencies and just let you install the thing you want to install (ngx-stripe).
With regards to fixing the error itself, there's not much you can do here. ngx-gallery-9 is using an older version of tslib, and hasn't been updated for a long time. There's currently an open bug requesting that the library maintainer update his packages.
More specifically,
Angular 15 requires tslib#"^2.3.0", but ngx-gallery-9 requires tslib#"^1.10.0". You can try forcing it to use the latest version by using --legacy-peer-deps during ALL your future npm installations, as well as running npm install tslib#^2.3.0 --save --legacy-peer-deps to manually choose to use the newer version, which will force the whole project to use tslib#"^2.3.0" and ignore ngx-gallery-9's complaints, but there's a strong possibility that ngx-gallery-9 won't work as expected.
Your best bet is to either
use a different gallery than ngx-gallery-9, or
Simply ignore the problem. Force everything to use tslib#"^2.3.0" with npm install tslib#^2.3.0 --save --legacy-peer-deps and hope ngx-gallery-9 won't have any errors, or
downgrade Angular to an earlier version (Which is very messy, and not really recommended unless you didn't intend to be using Angular 15).
Edit:
Or instead undo all the changes that npm-check-updates did, and instead just install an older version of ngx-stripe that's compatible with all of your packages. ngx-stripe has a chart showing which version to use depending on your version of Angular, here: https://www.npmjs.com/package/ngx-stripe
Just type:
npm install ngx-stripe #stripe/stripe-js --force
or npm install ngx-stripe #stripe/stripe-js--legacy-peer-deps

I'm trying to learn react/typescript and I'm following a tutorial line for line, but somehow getting this error when trying to install either #chakra-ui/react or #chakra-ui/core. It seems like a dependecy issue with react having been updated. Should I rollback react?

With this command you can solve the problem:
npm i #chakra-ui/react --legacy-peer-deps
I had the same issue but in Vue. I ran the following commands and it started working:
vue create test -p default && cd test && vue serve src/main.js,
It seems like it created a folder running some tests.
Then I ran: npm i -g #vue/cli-service-global..
Then: npm run serve-- to initiate the vue server.
Hopefully it gives you an idea how to solve that in React.
Good luck!
