有什么想法如何手动安装knitr模块吗?
Any ideas how to install the knitr-module manually?

推荐答案
LyX中knitr模块的唯一要求是R:您必须确保可执行文件Rscript在您的PATH中；您可以通过以下方式对其进行测试:
The only requirement of the knitr module in LyX is R: you have to make sure the executable Rscript is in your PATH; you can test it by:
which Rscript
如果看到Rscript的路径，就可以开始使用了(工具->重新配置)；否则，您必须告诉LyX Rscript在哪里(将路径添加到PATH prefix):
If you see the path to Rscript, you are ready to go (Tools-->Reconfigure); otherwise you have to tell LyX where is Rscript (add the path to PATH prefix):
然后重新配置LyX.
您可以通过在R中执行以下操作来获取Rscript的路径:
You can get the path to Rscript by executing this in R:
R.home('bin')
