renv:restore() 在 windows 中总是失败

问题描述

每当我想使用 renv:restore() 在我的 Windows 机器上重新创建一个项目时,它总是无法安装软件包。我总是得到同样的错误(虽然包可能会改变):

Retrieving 'https://cloud.r-project.org/src/contrib/Archive/xfun/xfun_0.21.tar.gz' ...
Error: Failed to retrieve package 'xfun'
In addition: Warning messages:
1: curl: (35) schannel: next InitializeSecurityContext Failed: UnkNown error (0x80092012) - The revocation function was unable to check revocation for the certificate. 
2: curl: (35) schannel: next InitializeSecurityContext Failed: UnkNown error (0x80092012) - The revocation function was unable to check revocation for the certificate. 
3: download Failed [error code 35] 
4: curl: (35) schannel: next InitializeSecurityContext Failed: UnkNown error (0x80092012) - The revocation function was unable to check revocation for the certificate. 
5: curl: (35) schannel: next InitializeSecurityContext Failed: UnkNown error (0x80092012) - The revocation function was unable to check revocation for the certificate. 

这是我的会话信息:

loaded via a namespace (and not attached):

这也可能有用:

> getoption("download.file.method")
[1] "wininet"
> renv:::renv_download_file_method()
[1] "curl"
>

运行后:Sys.setenv(RENV_DOWNLOAD_METHOD = "curl")(或 wininetlibcurl)我总是得到和以前一样的错误

作为一种解决方法,我执行了以下操作:

  1. 关闭项目
  2. 正常安装包(没有 renv)
  3. 使用 renv 打开项目
  4. 恢复快照

如果之前已经安装了这些包,它们将被符号链接并且它们会起作用。

不幸的是,这非常麻烦,因为许多包都有依赖项,我必须手动安装它们,而这正是我想要避免的事情之一,也是使用 renv 的原因之一!

解决方法

为了文档起见:在遵循来自 https://github.com/rstudio/renv/issues/735#issuecomment-825778542 的这个答案 Kevin Ushey 之后,我设法使它工作:

  1. renv 更新到最新版本(当前为 0.13.2)
  2. 运行Sys.setenv(RENV_DOWNLOAD_METHOD = "wininet")
  3. 运行renv::restore()
