r语言 - 当我在项目中使用 renv 包时，我无法安装 sf 包

Question

我在Rstudio中启动了一个新项目，并选择使用renv。我做的第一件事是输入命令install.packages('sf')， R返回下面的消息。如何继续?

> install.packages('sf')
Error: package 'sf' is not available
In addition: Warning messages:
1: could not retrieve available packages for url "https://cran.rstudio.com/src/contrib" 
2: could not retrieve available packages for url "https://cran.rstudio.com/bin/windows/contrib/4.1" 
3: curl: (35) schannel: next InitializeSecurityContext failed: Unknown error (0x80092012) - A função de revogação não pôde verificar a revogação do certificado. 
4: package 'sf' is not available 
5: failed to retrieve 'https://rstudio-buildtools.s3.amazonaws.com/renv/mran/packages.rds' [error code 35]

Answer 1

正如@KevinUshey所指出的，我能够通过以下方式下载它:

Sys.setenv(RENV_DOWNLOAD_FILE_METHOD = "libcurl")

Answer 2

同样的事情也发生在我身上。

最后，我发现Avast勒索软件模块阻塞了连接。试试禁用杀毒软件，看看会发生什么。
