How to install Swagger in Nestjs?

i can't install swagger in my nestjs application. When I try, I get a Error:

How to resolve this?

NestJS 9 was recently released (2 days ago).
https://trilon.io/blog/nestjs-9-is-now-available.
Changes have been made to the #nestjs/swagger package. You are installing the latest version which has peer dependencies on NestJS 9 while your project is still on version 8.4.7.
The error is saying it cannot resolve the requested peer dependency #nestjs/common#^9.0.0. It does find #nestjs/common#8.4.7 instead, but that's not compatible.
Either upgrade NestJS or install an older version of the #nestjs/swagger package that is compatible with the NestJS version your application uses. Version 5.2.1 should work for you.
yarn add #nestjs/swagger#5.2.1
OR
npm i #nestjs/swagger#5.2.1

I try to run the command npm install --save opensea-js, but I always end up with an error. I tried to clean NPM's cache, I have even reinstalled Node. I am on Windows. The stack trace is the following:

Does someone have an idea how I can solve this? Thank you in advance!

Try switching to Node.js version 8.11 to make sure common crypto dependencies work.
Execute nvm use, if you have Node Version Manager.
Try installing web3
from the opensea-js npm page

Try this :
npm i -g --force npm (note the --force flag)
If your output is get running npm install -g npm:
You can fix it with "brew reinstall node"
So :
brew reinstall node
npm i -g --force npm

I had the same problem when coding my app (MEVN) and using the command vue init webpack client.
So I did a bit of research notably on npm to see what was wrong and found this: https://www.npmjs.com/package/vue-cli so apparently you can't use this command anymore.
So if you wish to use the vue cli you need to install it trough npm install -g #vue/cli and then run vue create <dir name>
For further information you can look into the documentation: https://www.npmjs.com/package/#vue/cli with the documentation on the vuejs website: https://cli.vuejs.org/
Hope this helps and have fun coding

Notes:
I have tried restarting my command line.
I have also tried npm cache clean --force
And googling about an hour.
Finally, what does that lightercollective is not recognized as.. in the above message means? Confused???

Install:
npm i -g lightercollective
They change stuff... you must specify version numbers when you get packages or it won't work in the future if there is some sort of a breaking change.

You can add lightercollective to your dependencies to solve the issue.
Official package page
"lightercollective": "^0.0.0"

Update webpack-cli: npm update webpack-cli --save-dev
In my situation, I went from 3.2.1 (which warned about "lightercollective") to 3.3.8. Seemed like the issue was resolved.
