npm ERR! Invalid response body while trying to fetch http://registry.npmjs.org/accepts: Integrity verification failed for <some key i probably shouldn't share>
I get this error on my RPI4 (raspbian) when trying to install angular cli and express. I downgraded to npm 6.13.7 as advised in another thread but no success.
Try clearing the cache and install again
npm cache clear --force
npm install
