最近有個(gè)任務(wù)要在新服務(wù)器上安裝R包，stringr是其中之一
新服務(wù)器的R版本是4.0.5，比我之前使用的4.0.2高一些
不知道是不是版本問(wèn)題，在其他服務(wù)器上只要一條install.packages('stringr')就能搞定的事，結(jié)果費(fèi)了我一下午。。。
用常規(guī)的install.packages命令安裝會(huì)報(bào)錯(cuò)，
installation of package ‘stringr’ had non-zero exit status
仔細(xì)看輸出的錯(cuò)誤信息，是因?yàn)閟tringr依賴的stringi包安裝失敗。
而stringi包安裝失敗的原因是有個(gè)文件無(wú)法下載：
Error in download.file(paste(href, fname, sep = ""), icudtzipfname, mode = "wb"): cannot open URL 'https://raw.githubusercontent.com/gagolews/stringi/master/src/icu69/data/icu4c-69_1-data-bin-l.zip'
icudt download failed
Error: Stopping on error
In addition: Warning messages:

好在這條錯(cuò)誤信息貼心的給出了icu文件的下載鏈接！
然而，直接用wget 下載鏈接中的文件也是不行滴~
根本原因在于下載這個(gè)包需要翻墻?。?！
好在這個(gè)庫(kù)文件不大，用瀏覽器+翻墻軟件可以輕松下載，然后上傳到服務(wù)器。
再?gòu)腻e(cuò)誤信息中找到stringi包的版本和下載鏈接（再次感謝R提供了詳盡的錯(cuò)誤信息）
trying URL 'https://mirrors.sjtug.sjtu.edu.cn/cran/src/contrib/stringi_1.7.8.tar.gz'
最后，當(dāng)下載安裝包和庫(kù)文件都下載完成后執(zhí)行手動(dòng)安裝
R CMD INSTALL --configure-vars='ICUDT_DIR=~/R/x86_64-pc-linux-gnu-library/' stringi_1.7.8.tar.gz
注： ICUDT_DIR是下載的icu4c-69_1-data-bin-l.zip庫(kù)文件所在目錄
安裝好stringi后再執(zhí)行install.packages('stringr')就很順利的安裝完成了
trying URL 'https://mirrors.sjtug.sjtu.edu.cn/cran/src/contrib/stringr_1.4.0.tar.gz'
