我在我的 Linux VM (Centos 7) 中从源代码安装了 mono 3.10.0

ASP.NET我已经使用主页上提供的链接安装了 KVMGithub 

curl -sSL https://raw.githubusercontent.com/aspnet/Home/master/kvminstall.sh | sh && source ~/.kre/kvm/kvm.sh

并且kpm restore正在工作文件并恢复所有包

但我无法 在Asp.Net Home Githubk kestrel的HelloMvc示例中运行 我给出了错误 

System.NullReferenceException: Object reference not set to an instance of an object
  at Microsoft.AspNet.Server.Kestrel.Networking.Libuv.loop_size () [0x00000] in <filename unknown>:0 
  at Microsoft.AspNet.Server.Kestrel.Networking.UvLoopHandle.Init (Microsoft.AspNet.Server.Kestrel.Networking.Libuv uv) [0x00000] in <filename unknown>:0 
  at Microsoft.AspNet.Server.Kestrel.KestrelThread.ThreadStart (System.Object parameter) [0x00000] in <filename unknown>:0

我也试过libuv从源头安装仍然没有运气

编辑

libuv 安装遵循的步骤：

wget http://dist.libuv.org/dist/v1.0.0-rc1/libuv-v1.0.0-rc2.tar.gz
tar -xvf libuv-v1.0.0-rc2.tar.gz
cd libuv-v1.0.0-rc2/
./gyp_uv.py -f make -Duv_library=shared_library
make -C out
sudo cp out/Debug/lib.target/libuv.so /usr/lib/libuv.so.1.0.0-rc2
sudo ln -s libuv.so.1.0.0-rc2 /usr/lib/libuv.so.1

Libuv再次安装后出现异常

看看http://carolynvanslyck.com/blog/2014/09/dotnet-vnext-impressions/关于 Kestrel 的部分。

wget http://dist.libuv.org/dist/v1.0.0-rc2/libuv-v1.0.0-rc2.tar.gz
tar -xvf libuv-v1.0.0-rc2.tar.gz
cd libuv-v1.0.0-rc2/
./gyp_uv.py -f make -Duv_library=shared_library
make -C out
sudo cp out/Debug/lib.target/libuv.so /usr/lib/libuv.so.1.0.0-rc2
sudo ln -s libuv.so.1.0.0-rc2 /usr/lib/libuv.so.1

这对我有用

看看http://olivierlefebvre.tumblr.com/post/101523386694/asp-vnext-alpa4-on-ubuntu

我就这样修好了。

使用的步骤

git clone https://github.com/joyent/libuv.git
cd libuv
sh autogen.sh
./configure
make
make check
sudo make install

最后通过向 lib 添加符号链接

ln /usr/local/lib/libuv.so -sf ~/.kpm/packages/Microsoft.AspNet.Server.Kestrel/1.0.0-alpha4/native/darwin/universal/libuv.dylib

您遇到了一个异常，因为您有两个名称相同但大小写不同的变量。开始前转储所有环境变量：

printenv > env.dump

找到重复的变量并在开始之前取消设置其中一个（在之前保存原始值以在之后恢复它）

这是带有示例的脚本 init.d

只需保存并取消设置变量：

TMP_SAVE_runlevel_VAR=$runlevel
unset runlevel

并恢复它：

export runlevel=$TMP_SAVE_runlevel_VAR
