命名参数“allowPrereleaseVersions”不能用于指定位置参数的参数

Question

尝试在单声道上构建 NuGet 并获得：

error CS1744: Named argument `allowPrereleaseVersions' cannot be used for a parameter which has positional argument specified

运行：

xbuild Build/Build.proj /p:Configuration="Mono Release" /t:GoMono || die

问题：它是什么？是错误还是我做错了什么？

一些分析...

代码：

    public void InstallPackage(string packageId, SemanticVersion version)
    {
        InstallPackage(packageId, version, ignoreDependencies: false, allowPrereleaseVersions: false);
    }

错误来自：https://github.com/mono/mono/blob/master/mcs/mcs/ecore.cs#L5324

是的，这是 mcs 编译器中的一个错误。您可以使用主版本或等待 3.2 更新来解决问题。
