我想從github安裝一個軟件包,但當我使用install_github
時,我總是收到錯誤。錯誤設置證書驗證位置,install_github
library(devtools) install_github(repo="swirl", username="ncarchedi") Installing github repo(s) swirl/master from ncarchedi Downloading swirl.zip from https://github.com/ncarchedi/swirl/archive/master.zip Error in function (type, msg, asError = TRUE) : error setting certificate verify locations: CAfile: /Library/Frameworks/R.framework/Versions/3.0/Resources/library/RCurl/CurlSSL/cacert.pem CApath: none
我試圖安裝幾個不同的包 (包括ggmap的更新版本),我總是得到同樣的錯誤。它 必須與RCurl有關,但我不明白問題 是什麼,或者如何解決它。我有devtools(版本1.3)和RCurl (版本1.95-4.1)。我在Mac上運行R版本3.0.1(「Good Sport」)。從sessionInfo()

看起來像一個RCurl問題。這個文件是否真的存在:/Library/Frameworks/R.framework/Versions/3.0/Resources/library/RCurl/CurlSSL/cacert.pem? – Thomas
嗯,在mac上適合我,10.8.5。這個安裝rcharts的評論可能是有用的https://github.com/ramnathv/rCharts/issues/135#issuecomment-20140615 – sckott
是的,@Thomas說,你有沒有安裝libcurl?嘗試在命令行上找到curl-config,看看它是否安裝,如果沒有在這裏安裝的方向http://www.omegahat.org/RCurl/FAQ.html雖然也許你不能安裝RCurl沒有curl已經安裝... – sckott
