CodePudding user response：

The problem is specific to node-sass, in this project it seems to be the only binary dependency that depends on a platform and Node version.

There is a message that lock file version is old, this means that it was created with another version of NPM (v6), this can be is a possible source of problems due to differences in resolved dependencies.

As the documentation lists, different node-sass versions are linked to different Node versions, "node-sass": "^4.12.0" suggests that the project is supposed to run with Node v12, while v16 was used.

Possible solutions are:

Switch to Node v12 for this project (can be too old for other ones) and run as is
Switch to Node v14 (the latest LTS release, less problems in general) and update node-sass to ^4.14
Stay with Node v16 and update node-sass to ^6.0
Stay with Node v16, remove node-sass, instead add platform-independent sass, follow migration guidelines for Dart Sass if problems arise (primarily / syntax)
