对象' C_stri_join'找不到 - 在Rstudio中使用knitr

标签: r rstudio knitr stringi

在Rstudio中使用编织按钮时,我收到错误object 'C_stri_join' not found

以下是一个例子:

---
title: "Sample Document"
output:
   html_document:
   toc: true
   theme: united
---

<!--
%\VignetteEngine{knitr::knitr}
%\VignetteIndexEntry{Basic test}
-->

Here we go

```{r}
x <- 1

str(x)
```

错误如下:

Error in stri_c(..., sep = sep, collapse = collapse, ignore_null = TRUE) : 
  object 'C_stri_join' not found
Calls: suppressPackageStartupMessages ... evaluate_call -> handle_output -> <Anonymous> -> str_c -> stri_c

这是在最近更新我的R套件之后发生的:

> sessionInfo()
R version 3.2.2 (2015-08-14)
Platform: x86_64-w64-mingw32/x64 (64-bit)
Running under: Windows 7 x64 (build 7601) Service Pack 1

locale:
[1] LC_COLLATE=English_United Kingdom.1252 
[2] LC_CTYPE=English_United Kingdom.1252   
[3] LC_MONETARY=English_United Kingdom.1252
[4] LC_NUMERIC=C                           
[5] LC_TIME=English_United Kingdom.1252    

attached base packages:

loaded via a namespace (and not attached):
[1] htmltools_0.2.6 tools_3.2.2     yaml_2.1.13     rmarkdown_0.8.1
[5] digest_0.6.8   

错误似乎源于对R代码块中str的调用,因为以下工作没有错误:

---
title: "Sample Document"
output:
  html_document:
    toc: true
    theme: united
---

<!--
%\VignetteEngine{knitr::knitr}
%\VignetteIndexEntry{Basic test}
-->

Here we go

```{r}
x <- 1

# str(x)
```

这类似于this issue,但那里的细节很少。

只需重新安装stringi包就可以解决这个问题。
