devtools：：install_github 错误：无法从 GitHub 安装'unknown package'

Question

使用devtools::install_github安装R包时出现错误

> devtools::install_github('cole-trapnell-lab/leidenbase')
Error: Failed to install 'unknown package' from GitHub:
SSL certificate problem: self signed certificate in certificate chain

我尝试了一个解决方案张贴在这里

library(httr)
set_config( config( ssl_verifypeer = 0L ) )

但仍然得到相同的错误。有什么建议吗?

当我运行你的代码时，我没有得到ssl错误，但是你可以尝试使用remotes::install_github()安装leidenbase包:

#install.packages("remotes")
library(remotes)
install_github('cole-trapnell-lab/leidenbase')

也可能值得通过anaconda加载openssl，例如conda install openssl(可能有帮助)。
