dnu restore exception on osx yosemite

[robertmircea]

I am trying to run a dnu restore on Mac for a very simple dnxcore50 project. When executing the command at prompt in the project directory, I receive the following exception:

dnu restore
System.TypeInitializationException: The type initializer for 'Microsoft.Framework.Runtime.Common.CommandLine.AnsiConsole' threw an exception. ---> System.PlatformNotSupportedException: This platform does not support getting the current color.
   at System.ConsolePal.get_ForegroundColor()
   at Microsoft.Framework.Runtime.Common.CommandLine.AnsiConsole..ctor(TextWriter writer)

   at System.ConsolePal.get_ForegroundColor()
   at Microsoft.Framework.Runtime.Common.CommandLine.AnsiConsole..ctor(TextWriter writer)
   at Microsoft.Framework.Runtime.Common.CommandLine.AnsiConsole..cctor()

The project is configured under the following runtime:

dnvm list

Active Version              Runtime Arch Location             Alias

  *    1.0.0-beta5-11682    coreclr x64  ~/.dnx/runtimes
       1.0.0-beta4          mono         ~/.dnx/runtimes      default

Any suggestion on how to do the package restore?

Thanks,
Robert

Dnu isn't supported on coreclr xplat yet. Use the mono dnu

[robertmircea]

When I switched to mono, dnu restore did its job, but when I ran the app:

dnx . run
System.InvalidOperationException: Failed to resolve the following dependencies for target framework 'DNX,Version=v4.5.1':
   test 1.0.0

Searched Locations:
  /Users/robert/dev/{name}/project.json

  /usr/local/Cellar/mono/4.0.1/lib/mono/4.5/{name}.dll
  /usr/local/Cellar/mono/4.0.1/lib/mono/4.5/Facades/{name}.dll

Try running 'dnu restore'.

  at Microsoft.Framework.ApplicationHost.Program.Main (System.String[] args) [0x00000] in <filename unknown>:0

My project.json looks like this:

{
    "version": "1.0.0-*",
    "code": ["**/*.cs"],

    "frameworks" : {
        "dnxcore50": {
            "dependencies": {
                "System.Console": "4.0.0-beta-22716"
            }
        }
    }
}

I just want to demo a simple app using coreclr on a Mac. Is this an option for the moment?

Regards,
Robert

[davidfowl]

Yes you almost got it working. Switch to mono run restore then switch back to coreclr to run. You'll probably run into other bugs but give it a try

[robertmircea]

David, I did this too. Sadly, it does not work either. It says I need to run again dnu restore which does not work.

When in CoreClr will be RTM, do I need to dnx . run even for a console app (will I be able to call the binary directly)? How can I distribute my app without the source code and still be able to run it on another computer?

One of my goals would be to build a Linux daemon (headless) app running with .Net coreclr. Also, in order to be a true Linux citizen, it would have to respond to Unix signals.

Is this type of apps subject to first .net coreclr version release?

[davidfowl]

Sometime before we ship. I don't have dates for you. We're no where near the release date as this is the first preview. I suggest you follow along with http://github.com/dotnet/coreclr and http://github.com/aspnet/dnx.

[davidfowl]

I missed some of your questions:

David, I did this too. Sadly, it does not work either. It says I need to run again dnu restore which does not work.

If you get the same error you missed something. Show me the exact error you get when you ran it on coreclr.

Run dnu publish --no-source to get a self contained image. That will make a cmd file for windows and an executable script for *nix (this is similar to how node runs npm for example).

One of my goals would be to build a Linux daemon (headless) app running with .Net coreclr. Also, in order to be a true Linux citizen, it would have to respond to Unix signals.

Unix signals are just APIs. If you want specific APIs then you should file issues on https://github.com/dotnet/corefx.

OK that's not what I said, try these exact commands:

dnvm install 1.0.0-beta5-11682 -u
dnu restore
dnvm use 1.0.0-beta5-11682 -r coreclr
dnx . run

I'm running into a similar issue on Ubuntu trying to get a three line hello world console app to run on dnxcore50. Except my stack trace complains that the "type initializer for 'libcrypto' threw an exception.". But there are a number of references to SHA1 methods in the stack.

I'm on 11744 on Ubuntu and I still had to use mono to do the package restore. That should work though. However, running my console app under coreclr beta5 11744 did not work.

[nickserv]

Try running it through the artifacts generated by dnu publish.
