What I did:

1. Git pull from main
2. run nvm use to use node v14.17.6 (npm v6.14.15) then npm install
3. delete package-lock.json then run npm install again

After steps 2 and 3, for some dependencies package-lock.json, npmjs changed to yarnpkg.

Questions:

1. Why did this happen since this project does not use yarn
2. How can I fix this

CodePudding user response：

try this -

npm cache clear - -force npx rimraf ./**/node_modules del package-lock.json

now run npm install again
