我使用的是LYX 2.0.5.1和RStudio 0.97.318的最新版本。我在R中安装了knitr，我的/ usr / bin / Rscript在LYX中是PATH前缀，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。我还能做什么？
谢谢！
更新：我在R中安装了stringer包，重新配置了，但是Lyx仍然给出了错误：

我没有必要在windows下安装stringr，它运行正常。谢谢你的帮助！
