由于 swift-nio 中的奇怪错误，Swift Vapor 项目无法编译

Question

I can't get my Swift Vapor project to compile (which was running fine before), because nio produces strange errors all of a sudden:

Also, swift package update produces this:

.build/checkouts/swift-nio: error: Couldn’t check out revision ‘546610d52b19be3e19935e0880bb06b9c03f5cef’

I already cleaned, deleted derived data and rebuilt....any ideas?

Answer 1

Besides cleaning & re-building the project, you can try deleting the following files / directories:

• /.build
• /.swiftpm
• /Package.resolved

Then, run swift package update and try to build the project again.
