我在 LyX 2.0.5.1 和 RStudio 0.97.318 上使用最新版本。我已经在 R 中安装了 knitr，我的 /usr/bin/Rscript 在 LYX 的 PATH 前缀中，但我仍然无法运行示例文件 knitr.lyx。我得到的错误是：
An error occurred while running:
Rscript --verbose --no-save --no-restore
"/Applications/LyX.app/Contents/Resources/scripts/lyxknitr.R"
"/var/folders/ls/mbs_stj505lc25gj2m7h5h100000gn/T/lyx_tmpdir.JL9170/lyx_tmpb...
我将 lyxknitr.R 更改为官方引用中列出的其他版本，它也不适用于它们。当我在 Windows 7 上做类似的事情时，它运行正常。我试图重新安装lyx，它没有帮助。我还可以做些什么？
谢谢！
更新：我在 R 中安装了 stringer 包，重新配置，但 Lyx 仍然给出错误：

我不必在 Windows 下安装 stringr，它工作正常。感谢帮助！
