renv:restore()总是在windows中失败

Question

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。我总是收到相同的错误(尽管包可能会改变)：

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：

这也可能是有用的：

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

在运行：Sys.setenv(RENV_DOWNLOAD_METHOD = "curl") (或wininet或libcurl)之后，我总是得到与以前相同的错误。

作为一种解决办法，我做了以下工作：

project

• Install

• 以正常方式关闭包(不使用重命名)

1. 使用renv
2. 还原快照

打开项目

如果以前已经安装了这些软件包，那么它们将是符号链接的，并且能够工作。

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

为了编写文档:在遵循了https://github.com/rstudio/renv/issues/735#issuecomment-825778542来自Kevin Ushey的回答之后，我设法使它工作起来：

Sys.setenv(RENV_DOWNLOAD_METHOD = "wininet")

• Run renv::restore()

1. 更新renv到最新版本(当前为0.13.2)
2. 运行
