How to install Yoeman on Ubuntu18.04

Question

I am installing Yeoman on my machine and ran this npm install -g yo This is giving me permission error:

npm ERR! code EACCES
npm ERR! syscall access
npm ERR! path /usr/local/nvm/versions/node/v12.16.1/lib/node_modules/yo
npm ERR! errno -13
npm ERR! Error: EACCES: permission denied, access '/usr/local/nvm/versions/node/v12.16.1/lib/node_modules/yo'
npm ERR!  [Error: EACCES: permission denied, access '/usr/local/nvm/versions/node/v12.16.1/lib/node_modules/yo'] {

npm ERR!   syscall: 'access',

npm ERR! }
npm ERR! 
npm ERR! The operation was rejected by your operating system.

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/siddharth/.npm/_logs/2020-04-24T22_31_29_025Z-debug.log

But this got resolved by attaching sudo

Now I am getting this error:

Running yo --version is giving zsh: command not found: yo I tried this https://stackoverflow.com/a/58277450/10309895 but this is also not working for me :,(
