DNX红隼＆QUOT; System.EntryPointNotFoundException：uv_loop_size＆QUOT; [英] dnx kestrel "System.EntryPointNotFoundException: uv_loop_size"

问题描述

我试图运行哟ASPNET创建了一个未经修改的Web API应用程序。

我得到这个错误：

  System.EntryPointNotFoundException：uv_loop_size
  在（包装管理到本机）Microsoft.AspNet.Server.Kestrel.Networking.Libuv + NativeDarwinMonoMethods：uv_loop_size（）
  在Microsoft.AspNet.Server.Kestrel.Networking.Libuv.loop_size（）＆所述; 0x42615b8 + 0x00014＆GT;上述＆lt;文件名未知＆GT;：0

解决方案

单声道，可视code，Xamarin Studio中，DNX，libuv，节点和RoberN给我一些明确的指针升级的许多重新安装后，我想通我应该检查我的PATH环境变量。
果然，当我添加/ usr / lib目录/：在/ usr / local / lib目录到我的道路，这一切都开始工作。

成功！

I'm trying to run an unmodified Web Api application created by yo aspnet.

I'm getting this error:

Update

I ran

 export DYLD_FALLBACK_LIBRARY_PATH=/Users/Andy/.dnx/packages/Microsoft.AspNet.Server.Kestrel/1.0.0-rc1-final/runtimes/osx/native/

which ended up giving me a different error when running dnx web:

解决方案

After many reinstalls of Mono, Visual Code, Xamarin Studio, DNX, libuv, an upgrade of Node and RoberN giving me some clear pointers, I figured I should check my PATH env variable. Sure enough, as soon as I added /usr/lib/:/usr/local/lib to my PATH, it all started working!

dnx web

Hosting environment: Production
Now listening on: http://localhost:5000
Application started. Press Ctrl+C to shut down.

Success!
