Bug
What is the current behavior?
When installing with cordova as a dependency, I receive lots of warnings in the form of: warning The case-insensitive file /Users/artlogic/Code/random/yarn-issue/node_modules/npm/node_modules/readable-stream/lib/internal/streams/BufferList.js shouldn't be copied twice in one bulk copy
These files all seem to be related to npm.
If the current behavior is a bug, please provide the steps to reproduce.
Create a simple package.json with cordova as a dependency:
{
"name": "yarn-issue",
"version": "1.0.0",
"main": "index.js",
"license": "MIT",
"dependencies": {
"cordova": "^7.0.1"
}
}Run yarn install.
See a lot of warnings that look like this: warning The case-insensitive file /Users/artlogic/Code/random/yarn-issue/node_modules/npm/node_modules/readable-stream/lib/internal/streams/BufferList.js shouldn't be copied twice in one bulk copy
What is the expected behavior?
I don't expect to see all these error messages - they were not appearing before.
