Any idea why protractor is getting installed in a different directory on mac m1 even after giving permission to /usr/local/lib/node_modules

Question

First error user@suser-Air / % npm install -g protractor

npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142

npm WARN deprecated har-validator@5.1.5: this library is no longer supported

npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules

npm ERR! code EACCES

npm ERR! syscall access

npm ERR! path /usr/local/lib/node_modules

Solution - I gave permission to the above path and ran again npm install -g protractor

Second error

user@suser-Air / % npm install -g protractor

npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142

npm WARN deprecated har-validator@5.1.5: this library is no longer supported

you need to run the command in sudo mode

sudo npm install -g protractor
