我正在尝试运行由yo aspnet创建的未经修改的Web Api应用程序。
我收到了这个错误:
System.EntryPointNotFoundException: uv_loop_size
at (wrapper managed-to-native) Microsoft.AspNet.Server.Kestrel.Networking.Libuv+NativeDarwinMonoMethods:uv_loop_size ()

有什么想法吗?
dnvm列表输出:

更新
我跑了
export DYLD_FALLBACK_LIBRARY_PATH=/Users/Andy/.dnx/packages/Microsoft.AspNet.Server.Kestrel/1.0.0-rc1-final/runtimes/osx/native/
最后在运行dnx web时出现了不同的错误:

仅供参考:这不是mono
相关的
它没有通过libuv
程序集找到System.Net.Libuv
本机库:
1st)运行dnvm list -detailed
以确定您正在使用的dnx运行时的位置,即
Active Version Runtime Architecture OperatingSystem Alias Location
------ ------- ------- ------------ --------------- ----- --------
1.0.0-beta8 mono linux/osx ~/.dnx/runtimes
1.0.0-rc1-final mono linux/osx ~/.dnx/runtimes
* 1.0.0-rc2-16177 mono linux/osx default ~/.dnx/runtimes
第二次我的dnx
次安装是$HOME/.dnx/runtime
(默认设置),因此我可以运行find ~/.dnx/packages -name "libuv*"
/Users/sushi/.dnx/packages/Microsoft.AspNet.Server.Kestrel/1.0.0-beta8/runtimes/osx/native/libuv.dylib
/Users/sushi/.dnx/packages/Microsoft.AspNet.Server.Kestrel/1.0.0-beta8/runtimes/win10-arm/native/libuv.dll
/Users/sushi/.dnx/packages/Microsoft.AspNet.Server.Kestrel/1.0.0-beta8/runtimes/win7-x64/native/libuv.dll
/Users/sushi/.dnx/packages/Microsoft.AspNet.Server.Kestrel/1.0.0-beta8/runtimes/win7-x86/native/libuv.dll
/Users/sushi/.dnx/packages/Microsoft.AspNet.Server.Kestrel/1.0.0-rc1-final/runtimes/osx/native/libuv.dylib
/Users/sushi/.dnx/packages/Microsoft.AspNet.Server.Kestrel/1.0.0-rc1-final/runtimes/win10-arm/native/libuv.dll
/Users/sushi/.dnx/packages/Microsoft.AspNet.Server.Kestrel/1.0.0-rc1-final/runtimes/win7-x64/native/libuv.dll
/Users/sushi/.dnx/packages/Microsoft.AspNet.Server.Kestrel/1.0.0-rc1-final/runtimes/win7-x86/native/libuv.dll
找到libuv.dylib
在您系统上的位置后,您可以设置环境。 var DYLD_FALLBACK_LIBRARY_PATH
到该目录:
export DYLD_FALLBACK_LIBRARY_PATH=/your/libuv/directory/location:$DYLD_FALLBACK_LIBRARY_PATH
再次运行dmvm cmd:
dnvm exec 1.0.0-rc2-16177 dnx web
注意:
在OS-X上libuv
也可以通过brew
@ stable 1.7.5版本获得,但我没有尝试过,因为MS没有对他们的libuv.dylib版本进行版本控制,所以我不确定是否是custom version or not ...(?)
otool -L /Users/sushi/.dnx/packages/Microsoft.AspNet.Server.Kestrel/1.0.0-rc1-final/runtimes/osx/native/libuv.dylib
/Users/sushi/.dnx/packages/Microsoft.AspNet.Server.Kestrel/1.0.0-rc1-final/runtimes/osx/native/libuv.dylib:
/Users/asplab/Documents/buildAgent/temp/buildTmp/fs-poll-5b0daf.out (compatibility version 0.0.0, current version 0.0.0)
答案 1 :(得分:0)
如果有人来这里寻找另一种解决方案......
我尝试了以上所有方法,包括多次重新安装所有内容和PATH更新但没有成功,最后根据解决方案here切换到CoreCLR,它终于有效了!
dnvm install 1.0.0-rc1-update1 -r coreclr -arch x64
dnvm use 1.0.0-rc1-update1 -r coreclr -arch x64
dnvm list
然后,转到您的项目并再次尝试
dnx web
