r - 使用 home-brew 和 r 4.1 在 Big Sur 上安装 rcurl 失败

Question

我正在尝试RCurl使用 Big Sur 和 R 4.1 在我的 macOS 上安装。请参阅下面的输出 - 它不起作用。我确实需要它，因为我需要它GenomeInfDB。

有谁知道如何用“命名空间”解决这个问题RCurl？

非常感谢您的建议。

谢谢

桑德

我在 macOS 上开发 R 包，强烈建议不要在 R 中的系统中激活 conda PATH。这会导致 R 选择 conda gcc，这与在 macOS 上构建许多 R 包不兼容。查看R for macOS 开发人员指南，其中详细解释了这一点。或者，您可以PATH使用Renviron文件在 R 中专门设置，这将有助于防止编译器与 conda 混淆gcc。

此外，从源代码构建包时，建议在 macOS 上使用CRAN R 二进制安装。不推荐通过 conda 获得的 R 版本用于在 macOS 上从源代码构建包。

这可以通过 Homebrew 安装，使用：

brew install --cask r
