unable to solve error code 1 when running"npm install"

Question

when I try to run "npm install" I get errors that I have brought parts of them here:

npm ERR! code 1
npm ERR! git dep preparation failed
npm ERR! command /usr/local/lib/node_modules/node/bin/node

npm ERR! npm WARN old lockfile 
npm ERR! npm WARN deprecated [email protected]: fsevents 1 will break on node v14+ and

after reading few articles , I used many commands like this:

npm cache clean --force

or npm i --package-lock-only

But none of them fixed the issue, even some of them like "npm audit fix --force" showed other types of errors.

Any advice would be appreciated.

What version of node and npm are you using?

I had the same error, spent hours Googling and trying the same things...

npm cache clean --force
rm -rf node_modules
rm -rf package-lock.json

The error remained...

I ended up downgrading my version of npm to 6.14.15. I was using the latest version of npm which I believe is 7.something. I downgraded to 6.14.15 because that's the one that comes in the stable node.js download.

I don't have the details on why it worked or what's different in the versions but running npm i worked for me after downgrading.
