【问题描述】：
我已经尝试了在 stackoverflow 上看到的主要修复，但没有运气：
- 关闭“使用安全下载方法”
- 将主 CRAN 存储库更改为全局
- 卸载/重新安装 R
Warning in install.packages :
unable to access index for repository http://cran.rstudio.com/bin/macosx/el-capitan/contrib/3.6:
cannot open URL "http://cran.rstudio.com/bin/macosx/el-capitan/contrib/3.6/PACKAGES"
有什么想法吗？这一切都是在尝试安装 pdftools（它本身与 pkgconfig 存在问题）之后开始的。
编辑： 这是完整的代码块。它设法从源下载，但随后给出零退出状态

您似乎由于某种原因无权访问存储库。您检查过防火墙、vpn 等设置吗？您是否尝试过从终端安装（例如，
RScript -e "install.packages('dplyr', repos = 'http://cran.rstudio.com/')"？或者尝试一些不同的镜像：cran.r-project.org/mirrors.html -
@JBGruber 感谢您的帮助！是的，检查了防火墙/vpn。从终端安装不起作用，不同的镜像也没有。
