如何在Lyx 2.0.3中安装knitr-module? [英] How to install the knitr-module in Lyx 2.0.3?

问题描述

我刚刚在iMac和MacBook Air上安装了Lyx 2.0.3.尝试在iMac上打开* .lyx文档时，出现以下错误消息:

I just installed Lyx 2.0.3 on my iMac and MacBook Air. When trying to open a *.lyx document on the iMac I get the following error-message:

此文档已请求模块编织器，但尚未请求 在可用模块列表中找到.如果您最近安装了它， 您可能需要重新配置LyX."

"The module knitr has been requested by this document but has not been found in the list of available modules. If you recently installed it, you probably need to reconfigure LyX."

在MacBook Air上，一切运行正常，没有任何错误.

On the MacBook Air everything runs fine without any errors.

有什么想法如何手动安装knitr模块吗?

Any ideas how to install the knitr-module manually?

谢谢

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')
