The `fs.relative()` method assumed that the file-system is a single tree, which is not the case in Windows, where you can have multiple drives, e.g. `C:`, `D:` etc. This commit changes `fs.relative()` so that it no longer forces the result to be a `PathSegment` and then flows that refactoring through the rest of the compiler-cli (and ngcc). The main difference is that now, in some cases, we needed to check whether the result is "rooted", i.e an `AbsoluteFsPath`, rather than a `PathSegment`, before using it. Fixes #36777 PR Close #37959
Angular Compatibility Compiler (ngcc)
This compiler will convert node_modules
compiled with ngc
, into node_modules
which
appear to have been compiled with ngtsc
.
This conversion will allow such "legacy" packages to be used by the Ivy rendering engine.
