vapor build --verbose
I get the error:

Does anyone have any idea what is going wrong there? Thanks in advance!

Answer 1

I found the solution:
$ brew doctor
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!
Warning: Unbrewed header files were found in /usr/local/include.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.
Unexpected header files:
/usr/local/include/base.h
/usr/local/include/bcj.h
/usr/local/include/block.h
/usr/local/include/cdefs.h
/usr/local/include/check.h
...
and solved the problem by deleting all "Unbrewed header files" from /usr/local/include/

Answer 2

That is bizarre! Just to confirm you’re in the right folder? If you run swift build does it do the same thing?

Answer 3

I had a similar issue unrelated to brew.
Error: backgroundExecute(code: 1, error: "/path/to/project: error: manifest parse error(s):\nInvalid version string: x.0.0\n", output: "")
My Package file looked like this;
...
.package(url: "https://github.com/../something.git", .upToNextMajor(from: "x.0.0")),
...
Looking into .upToNextMajor(from:) I didn't see any parsing for 'x' so I just went to the github page and found which major version I wanted and replaced it for the placeholder in my package file:
...
.package(url: "https://github.com/../something.git", .upToNextMajor(from: "1.0.0")),
...
This resolved the issue for me, Hope this helps the next person that comes by! upvote if it helps you!
