安装后无法加载 kableExtra

Question

如果我可以更好地格式化，我提前道歉 - 我是 Stack Overflow 的新手。我正在尝试安装 kableExtra 包。虽然我能够安装它，但在尝试加载包时我不断收到此错误消息。我该如何解决这个问题？

install.packages("kableExtra", dependencies = TRUE)

library(kableExtra)

您的 systemfonts 软件包副本似乎已损坏。您可以尝试在安装 kableExtra 之前重新安装它，但它可能会安装失败，因为您似乎还缺少 /opt/X11/lib/libfreetype.6.dylib 动态库。您可能需要安装它：但我不能建议如何在不了解您的系统的情况下安装它。

您编辑了问题以包含运行ning sessionInfo() 的结果；谢谢！这告诉我的是，您正在运行ning Mac: 所以您将安装 XQuartz 以获取 X11 库。我认为这应该让你 libfreetype.

我也看到你是运行ning R version 3.6.1。那是 2 岁的，当前的软件包可能不可用。保持最新通常是个好主意，最近发布了 R 4.1.0，因此我建议更新到该版本。在更新之前，运行 pkgnames <- rownames(installed.packages(priority = "NA")); dput(pkgnames) 并将结果保存到文件中。然后更新R，并且运行

pkgnames <- [ the long string you saved ]
install.packages(pkgnames)

安装您正在使用的任何贡献包的最新版本。
