npm ERR! While resolving: @sitecore-jss/sitecore-jss-nextjs@19.0.2

Context and Solution: This is an error that occurs when you try to execute npm install (in my case, for Sitecore Edge Demo project: the \Sitecore.Demo.Edge\Website\src\rendering folder). This error was disallowing the npm_modules folder to be created. I feel this is a general error and can occur in conjunction with npm install command. When I checked the esolve-report.txt under \AppData\Local\npm-cache, i found that I could use the --force option on npm install. Once I executed npm install --force, this error was gone and node_modules folder was also created as part of the npm install.

Error:

npm WARN config global `--global`, `--local` are deprecated. Use `--location=global` instead.
