Rstudio的编织按钮无法编织包含rJava软件包的rmark（Rmd）文件。但是，如果我使用rmarkdown::render()，则相同的Rmd文件会呈现为html而不会出现问题。Rstudio编织按钮无法加载rJava
我可以重现错误与下面的代码：
内容test.Rmd的：
---
title: "test"
output: html_document
---
```{r}
library(rJava)
```
点击针织按钮按钮将返回：
processing file: test.Rmd
Error : .onLoad failed in loadNamespace() for 'rJava', details:
call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared object '/Library/Frameworks/R.framework/Versions/3.3/Resources/library/rJava/libs/rJava.so':
dlopen(/Library/Frameworks/R.framework/Versions/3.3/Resources/library/rJava/libs/rJava.so, 6): Library not loaded: @rpath/libjvm.dylib
Referenced from: /Library/Frameworks/R.framework/Versions/3.3/Resources/library/rJava/libs/rJava.so
Reason: image not found
Quitting from lines 7-8 (test.Rmd)
Error: package or namespace load failed for 'rJava'
Execution halted
而且rmarkdown::render("test.Rmd")工作正常。另外，通常运行library(rJava)（不是针织）也可以正常工作（在RStudio中）。
在macOS Sierra 10.12中使用RStudio version 1.0.136，knitr 1.15.1，rmarkdown 1.3，rJava 0.9-8，R 3.3.2。
更新：根据@ r2evans的要求添加Sys.getenv()的输出。 DYLD_FALLBACK_LIBRARY_PATH的值有所不同，但我不知道这是否意义重大。我用XXX替换了一些私人信息。

UPDATE2在从@ r2evans
评论，包括从DYLD_FALLBACK_LIBRARY_PATH render()在.Rmd改变了重新按照预期的Sys.getenv()的结果，但编织按钮（与上述相同的错误信息）的错误行为仍然存在，并且render()中没有错误。新.Rmd内容是：
---
title: "test2"
output: html_document
---
```{r}
Sys.setenv(DYLD_FALLBACK_LIBRARY_PATH="/Library/Frameworks/R.framework/Resources/lib:/Library/Frameworks/R.framework/Resources/lib:/Library/Frameworks/R.framework/Resources/lib:/Library/Frameworks/R.framework/Resources/lib:/Users/Jayme/lib:/usr/local/lib:/usr/lib::::::::")
library(rJava)
```
有趣的是，在此test2.Rmd略高于使用render()，并且包括Sys.getenv()现在输出两个新的变量，之前不存在，不存在使用针织按钮：
我没有，如果它是有道理的，但我尝试了一个新的.Rmd（下），它仍然给出相同的错误
---
title: "test3"
output: html_document
---
```{r}
Sys.setenv(DYLD_FALLBACK_LIBRARY_PATH="/Library/Frameworks/R.framework/Resources/lib:/Library/Frameworks/R.framework/Resources/lib:/Library/Frameworks/R.framework/Resources/lib:/Library/Frameworks/R.framework/Resources/lib:/Users/Jayme/lib:/usr/local/lib:/usr/lib::::::::")
Sys.setenv(DYLD_LIBRARY_PATH="/Library/Java/JavaVirtualMachines/jdk1.8.0_101.jdk/Contents/Home/jre/lib/server")
Sys.setenv(LD_LIBRARY_PATH= ":@[email protected]")
library(rJava)
```
我无法重现你的错误......我的工作系统，Ubuntu的LTS 16.04对所有的罚款。其余的软件包与我的系统相同。 –
在'render'和''knit''中运行'Sys.getenv（）'可能会有所帮助。寻找差异，特别是在“PATH”和任何“LIB”相关变量中。 – r2evans
@ r2evans更新了所需信息的问题。 –
