我已经阅读了教程,并且能够生成.cs文件,但它不包含我的任何服务或rpc定义。
我已经将protoc
添加到我的路径中,并从项目目录中进行添加。
protoc project1.proto --csharp_out="C:\output" --plugin=protoc-gen-grpc="c:\Users\me\.nuget\packages\grpc.tools\1.8.0\tools\windows_x64\grpc_csharp_plugin.exe"
控制台中无错误输出

对于其他发现这一点的人来说,这里只是一个空洞的评论,关于这一点的文档非常过时,而且是完全错误的。
安装Grpc.Tools
不会在包文件夹中安装任何东西;这是遗留行为,即使在windows上也不再是这样。
安装Grpc.Tools
时,它将隐藏在本地程序包缓存中,您可以通过调用以下命令查看:
$ dotnet nuget locals all --list
info : http-cache: /Users/doug/.local/share/NuGet/v3-cache
info : global-packages: /Users/doug/.nuget/packages/
info : temp: /var/folders/xx/s2hnzbrj3yn4hp1bg8q9gb_m0000gn/T/NuGetScratch
您需要的二进制文件将位于其中一个文件夹中。
最简单的方法是直接从nuget下载Grpc.Tools
包,并将其安装到本地。
我已经破解了这个小助手脚本来做这件事,它在windows/mac/linux上工作,这可能会减轻其他人开始使用它的难度:
