Can'；t使用最新版本的RProvider:R.NET初始化失败

遇到来自RProvider的相当奇怪的行为：

RDotNet的最新版本本身工作正常。 RProvider的旧版本（高达1.1.15）也不会产生任何问题。 但任何最新版本（从1.1.17到最新的1.1.22）都会抛出以下错误：“R.NET初始化失败”（即使没有导入RProvider模块）。此外，代码的第一行以红色突出显示，并带有以下警告：（“引用的程序集RProvider.dll具有程序集级属性TypeProviderAssemblyAttribute，但未找到公共类型提供程序类”）。 深入研究这个问题，我发现RProvider日志抱怨缺少R.dll（当然是存在的）
