Question

我尝试按照此处的一个答案安装.NET Core运行时环境：Is it possible to run .NET Core on Raspberry PI?

我已经检查过我已经安装了所有需要的软件包，但是当我运行＆＃34; dotnet --info＆＃34;我只是得到分段错误。 Strace没有对可能遗漏的内容提出好的建议：https://pastebin.com/rBUbiYkV

我接下来应该尝试什么？

Answer 1

Raspberry Pi 1包含an ARMv6 processor。

.NET Core需要一个可以execute the ARMv7 instruction set的处理器，因为这就是JIT发出的：

注意：不支持Pi Zero，因为.NET Core JIT依赖于Pi Zero上没有的armv7指令。

所以这不会起作用。抱歉。尝试使用Raspberry Pi 2或3。

（如果你疯狂冒险，你可以尝试自己移植JIT。我不会尝试这个，除非你非常非常适合编写ARM程序集，C，C ++，C＃并深入理解编译器）

Answer 2

是的，.Net Core将在Raspberry Pi 3而不是2上运行。

您可以在stackoverflow中的 here 中找到安装过程。
