安装视图 [英] Installing Views

问题描述

最近在Fedora 24上安装了Microsoft R Open 3.3.1。之前对R有点熟悉，但是已经卸载并且干净利落。我想要做的第一件事是重新安装计量经济学软件包，因此，按照说明：



install.packages（" ctv"）

library（ctv）

install.views（" Econometrics"）



我遇到了错误。

Recently installed Microsoft R Open 3.3.1 on Fedora 24. Somewhat familiar with R from before, but uninstalled and went with a clean slate. The first thing I wanted to do was reinstall the econometrics package and so, following the instructions:

install.packages("ctv")
library(ctv)
install.views("Econometrics")

I was faced with the error.

url错误（paste（contriburl [i]，" Views.rds"，sep =" /"），open =" rb"）：


 无法打开连接

另外：警告信息：

在网址中（粘贴（contriburl [i]，"Views.rds"，sep =" /"） ，open =" rb"）：

 网址"https://mran.revolutionanalytics.com/snapshot/2016-07-01/src/contrib/Views.rds"：状态为"SSL CA证书问题（路径？访问权限？）"

Error in url(paste(contriburl[i], "Views.rds", sep = "/"), open = "rb") :
  cannot open connection
In addition: Warning message:
In url(paste(contriburl[i], "Views.rds", sep = "/"), open = "rb") :
  URL 'https://mran.revolutionanalytics.com/snapshot/2016-07-01/src/contrib/Views.rds': status was 'Problem with the SSL CA cert (path? access rights?)'

我不清楚如何从这里开始。

I'm not clear how to proceed from here.

推荐答案

看起来ctv包无法找到我们随MRO一起提供的CA捆绑包。你可以尝试这个：

It looks like the ctv package isn't able to find the CA bundle that we ship with MRO. Can you try this:

Sys.setenv（CURL_CA_BUNDLE =" /usr/lib64/microsoft-r/3.3/lib64/R/ lib / microsoft -r-cacert.pem"）

Sys.setenv(CURL_CA_BUNDLE = "/usr/lib64/microsoft-r/3.3/lib64/R/lib/microsoft-r-cacert.pem")

library（ctv）

library(ctv)

install.views（" Econometrics"）

install.views("Econometrics")

编辑：

为了防止这有用，我还需要在fedora 24上按顺序执行以下操作安装软件包

Just in case this is helpful, I needed to also do the following on fedora 24 in order to install the package

yum groupinstall"开发工具"

yum install gcc -c ++ gcc-gfortran libpng-devel libxml2- devel libcurl-devel openssl-devel libjpeg-devel gmp-devel gsl-devel

yum groupinstall "Development Tools"
yum install gcc-c++ gcc-gfortran libpng-devel libxml2-devel libcurl-devel openssl-devel libjpeg-devel gmp-devel gsl-devel
