Description

  • I have searched the existing issues
Current Behavior

When installing a local dependency in Windows, the posix paths under "package-lock.dependencies" are converted to Windows style paths, with double backslashes. The paths in "package.json" and under "package-lock.packages" are kept unix style.

Expected Behavior

package-lock is kept as is when installing dependencies.

Steps To Reproduce

Clone and follow the instructions on sample repository.

Environment
  • OS: Windows 10 20h2
  • Node: 16.2.0
  • npm: 7.13.0

Research direction

Clone the linked sample repository and follow its reproduction steps on Windows with the stated Node and npm versions. Compare package-lock.dependencies with package.json and package-lock.packages; done means installing the local dependency no longer changes POSIX paths to doubled backslashes.
