The library 'libhostpolicy.dylib' required to execute the application.

Hello,

When I installed https://www.npmjs.com/package/nswag, I receive this weird “The library ‘libhostpolicy.dylib’ required to execute the application was not found in ___”

NSwag NPM CLI
A fatal error was encountered. The library 'libhostpolicy.dylib' required to execute the application was not found in '/Users/xxx/.nvm/versions/node/v8.1.2/lib/node_modules/nswag/bin/binaries/netcoreapp1.1/'.
child_process.js:631
    throw err;
    ^

Error: Command failed: dotnet "/Users/xxx/.nvm/versions/node/v8.1.2/lib/node_modules/nswag/bin/binaries/netcoreapp1.1/dotnet-nswag.dll" help --core 1.1

I’ve tried a few things.

1. Tried looking for the dynamic library online. Apparently a lot of people seem to have this issue with @dotnet/cli, A quick search in the issues seem that a lot of MacOS folks have similar issues. However I could not isolate the issue.
2. Install different versions of the dotnet core.
3. Trying to build the NSwag with build/*.bat but did not compile successfully.

Help would be greatly appreciated!

Hey I just encountered the same problem with the current npm package under Mac OS. Adding a <OutputType>Exe</OutputType> to the main PropertyGroup of NSwag.ConsoleCore/NSwag.ConsoleCore.csproj and rebuilding under Windows fixes the issue. It produces a valid NPM binary configuration by adding a dotnet-nswag.runtimeconfig.json to the publish directory. With that file present, the execution works fine.
