安装stringi多次失败。

Question

我正在尝试安装likert，这需要stringi。

install.package("likert")无法安装stringi。

来自CRAN的install.package("stringi")也失败了：

trying URL 'https://cran.rstudio.com/bin/macosx/contrib/4.2/stringi_1.7.6.tgz'
Content type 'application/x-gzip' length 14390020 bytes (13.7 MB)
==================================
downloaded 9.3 MB

Warning in install.packages :
  downloaded length 9800943 != reported length 14390020
Warning in install.packages :
  URL 'https://cran.rstudio.com/bin/macosx/contrib/4.2/stringi_1.7.6.tgz': Timeout of 60 seconds was reached
Error in download.file(url, destfile, method, mode = "wb", ...) : 
  download from 'https://cran.rstudio.com/bin/macosx/contrib/4.2/stringi_1.7.6.tgz' failed
Warning in install.packages :
  download of package ‘stringi’ failed

我从https://cran.r-project.org/web/packages/stringi/index.html下载了这个软件包，并尝试安装：install.packages("~/Desktop/downloads/stringi_1.7.6.tgz", repos = NULL, type = .Platform$pkgType)

但这也失败了：

Error: package or namespace load failed for ‘stringi’ in dyn.load(file, DLLpath = DLLpath, ...):
 unable to load shared object '/Library/Frameworks/R.framework/Versions/4.2/Resources/library/stringi/libs/stringi.so':

  Referenced from: /Library/Frameworks/R.framework/Versions/4.2/Resources/library/stringi/libs/stringi.so

怎么一回事？我有最新版本的R和R工作室的Mac。

我想通了。问题是超时。装载时间太长了。我通过将超时时间从60秒更改为一个更大的数字来修正它：

getOption('timeout')
[1] 60
options(timeout=300)
