大佬教程收集整理的这篇文章主要介绍了无法使用 home-brew 和 r 4.1 在 Big Sur 上安装 rcurl，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
我正在尝试使用 Big Sur 和 R 4.1 在我的 macOS 上安装 RCurl。请参阅下面的输出 - 它不起作用。
我确实需要它，因为我需要 GenomeInfdb。@H_801_7@
有谁知道如何使用“命名空间”和 RCurl 解决这个问题？@H_801_7@
非常感谢您的建议。@H_801_7@
谢谢@H_801_7@

我在 macOS 上开发 R 包，强烈建议不要在 R 内的系统 PATH 中激活 conda。这会导致 R 选择 conda gcc，这与构建许多不兼容macOS 上的 R 包。看看 R for macOS Developers guide，它详细解释了这一点。或者，您可以使用 PATH 文件在 R 中专门设置 Renviron，这将有助于防止编译器与 conda gcc 混淆。@H_801_7@
此外，从源代码构建软件包时，建议在 macOS 上使用 CRAN R binary 安装。不建议将通过 conda 提供的 R 版本用于在 macOS 上从源代码构建包。@H_801_7@
这可以通过 Homebrew 安装：@H_801_7@
brew install --cask r
