“magrittr”403 禁止且无法安装

问：

我从 CRAN 下载软件包时遇到问题。最初，我的公司似乎阻止我下载 zip 文件。我跳过了重重障碍，获得了高水平的互联网访问，还尝试了一些简单的修复程序，但问题仍然存在。我可以从 CRAN 下载其他软件包，但似乎被认为不安全，无论我尝试什么，都会得到 403ed。magrittrmagrittr

似乎也是很多包都需要的核心包之一，所以没有它的生活会很辛苦。magrittr

我已经取消了“选项”中的“使用安全方法进行https下载”选项。

我已将下载方法设置为options(download.file.method = "wininet")

我尝试将全局存储库更改为其他存储库。

我还尝试安装存档版本。

从网络安全方面，他们可以看到 zip URL 被 Zscaler 阻止。但是其他包的 zip URL 没有被阻止。magrittr
