Kestrel命令抛出无法加载libuv。确保libuv已安装并可作为libuv.so.1提供。

Question

我在试着运行https://github.com/aspnet/home的样本

我遵循了文档的所有步骤，但我无法使它工作。

我正在运行dnx . kestrel (在CentOS上)，错误是：

System.InvalidOperationException: Unable to load libuv. Make sure libuv is installed and available as libuv.so.1
  at Microsoft.AspNet.Server.Kestrel.Networking.Libuv.Load (System.String dllToLoad) [0x00000] in <filename unknown>:0
  at Microsoft.AspNet.Server.Kestrel.KestrelEngine..ctor (ILibraryManager libraryManager, IApplicationShutdown appShutdownService) [0x00000] in <filename unknown>:0
  at Kestrel.ServerFactory.Start (IServerInformation serverInformation, System.Func`2 application) [0x00000] in <filename unknown>:0
  at Microsoft.AspNet.Hosting.Internal.HostingEngine.Start () [0x00000] in <filename unknown>:0

我有libuv.so.1.0.0在/usr/local/lib

[/usr/local/lib]$ ls
libuv.a  libuv.la  libuv.so  libuv.so.1  libuv.so.1.0.0  pkgconfig

我还为libuv.so.1在/usr/lib和/usr/lib64中添加了符号链接。

我甚至检查了kestrel源代码，但我找不到问题所在。

我遗漏了什么？

将库加载程序路径设置为包含本地库dir，而LoadLibrary在Libuv.cs中应该可以找到它：

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
dnx . kestrel

man dlopen获得更多详细信息：

Linux Shared Library Search Path
From the dlopen(3) man page, the necessary shared libraries needed by the program are searched for in the following order:

1) A colon-separated list of directories in the user’s LD_LIBRARY_PATH environment variable.
