Question

我在R中安装sourcetools时遇到问题，这是安装闪亮的依赖项之一。

R版本为3.4.0。

你可以从以下方面做出正面和反面：

install.packages('sourcetools', repos='http://cran.us.r-project.org')
trying URL 'http://cran.us.r-project.org/src/contrib/sourcetools_0.1.2.tar.gz'
Content type 'application/x-gzip' length 16227 bytes (15 KB)

CRAN上的sourcetools版本需要具有C ++ 11功能的编译器。开发版本解除了这一限制，并试图遵循C ++ 98标准，以便它可以在较旧的编译器上构建。

您应该可以使用例如

安装sourcetools的开发版本

devtools::install_github("kevinushey/sourcetools")
