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:

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 wininet
或libcurl
)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:
- 关闭项目
- 正常安装包(没有 renv)
- 使用 renv 打开项目
- 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:
- 将
renv
更新到最新版本(当前为 0.13.2) - 运行
Sys.setenv(RENV_DOWNLOAD_METHOD = "wininet")
- 运行
renv::restore()
