c# - 为 C# 安装 Graphhopper Directions API 客户端期间出现错误

Question

我想使用通过这个 git repo提供的 C# 的 Graphhopper API 客户端库

我按照自述文件提出了以下错误。

在运行 build.bat 时，我收到以下错误：

...\directions-api-clients\csharp>build.bat

  C:\Users\richard.wieditz\.nuget\packages\

This compiler is provided as part of the Microsoft (R) .NET Framework, but only supports language versions up to C# 5, which is no longer the latest version. For compilers that support newer versions of the C# programming language, see http://go.microsoft.com/fwlink/?LinkID=533240

src\GraphHopper\Api\MatrixApi.cs(35,38): error CS1001: Identifier expected
src\GraphHopper\Api\MatrixApi.cs(46,63): error CS1001: Identifier expected
...

我没有更改direction-api-clients 目录中的任何文件。我按照自述文件中的说明进行操作。

如果我是对的，我的编译器或某些需求版本已经过时，所以我无法正确编译必要的文件。我对 C# 开发还很陌生，到目前为止，我自己无法找出错误。也许你可以指出我正确的方向。

此致。最佳答案的 Cookie :)

更新：

我使用最新的 C# 编译器并再次运行 build.bat 文件。这给了我一些改变，但仍然失败并出现错误：

../graphhopper_csharp_client>build.bat
All packages listed in "C..\graphhopper_csharp_client\src\IO.Swagger\packages.config" are already installed
..\graphhopper_csharp_client>if not exist ".\bin" mkdir bin

更新 2：

按照jdweng的建议。非常感谢您的支持。

使用干净的 bin 目录重建并没有修复错误。bin 目录下没有调试和发布文件夹。

csproj 文件包括：

到目前为止，我无法从该文件中获得有价值的信息。我将尝试通过邮件联系 graphhopper 支持。

我将继续为那些对此问题感兴趣的人更新此线程。
