On 'npm outdated' error: Only tag, version, and range are supported

Question

There are "named" references in my package.json (npm 7.20.3)

 "bootstrap-legacy": "npm:bootstrap@4.6.0",
 "sass-legacy": "npm:sass@1.32.13",

But after this npm outdated stop working:

npm ERR! Only tag, version, and range are supported npm ERR! A complete log of this run can be found in: npm ERR! ..\\npm-cache_logs\\2021-09-09T09_14_26_242Z-debug.log

Nothing interesting in the log

Do we have any workaround for this? Any key for the outdated command ? Other command to list outdated packages? Solved in later npm versions?

PS npm install works well.

Answer 1

there is an open issue on github which you can follow and like in order to get it fixed. There seems not to be a general solution to the alias issue, but in some cases the usage of aliases can be avoided.
