I run npm i and got this message:

npm i
npm ERR! Cannot read property 'name' of undefined

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/minta-dan/.npm/_logs/2021-02-01T12_07_22_367Z-debug.log

in the log I can tell that everything installed but:

I ran into this when trying to run npm install on a project with a yarn.lock file. If that's your situation, I suggest you run yarn install instead or do the conversion

I had this same problem not running npm i but while installing the ycm-core/YouCompleteMe plugin for vim. Running npm install -g npm@latest didn't solve the issue. But it stopped occurring only when I changed the 'global' default to false in file ~/.nmprc:

global=false

Before that, I updated all global packages without success:

npm -g outdated
npm -g update

I learned that maybe it is a good idea to use global only when required with '-g' flag.

I've got the same error, but for me, the solution was the rollback of npm to the 7.0.0 version (from the latest - 7.17.0).
