devtools install_github安装报错: CAfile: microsoft-r-cacert.pem

报错信息

> install_github("dengfei2013/GS")
Installation failed: error setting certificate verify locations:
  CAfile: microsoft-r-cacert.pem
  CApath: none

解决方法

1. 进入R, 卸载curl, httr, 重新安装

remove.packages(c("curl","httr"))
install.packages(c("curl", "httr"))

2. 更换microsoft-r-cacert.pem

Sys.setenv(CURL_CA_BUNDLE="/opt/microsoft/ropen/3.5.1/lib64/R/lib/microsoft-r-cacert.pem")

里面是我的路径, 你可以通过locate ,查看你的pem路径, 进行替换

3. 测试install_github

library(devtools)
install_github("dengfei2013/GS")

> install_github("dengfei2013/GS")
