‘magrittr’403 禁止，无法安装

Question

我在从 CRAN 下载

magrittr

包时遇到问题。最初，我的公司似乎阻止我下载 zip 文件。我克服了困难并获得了高级别的互联网访问权限，还尝试了一些简单的修复，但问题仍然存在。我可以从 CRAN 下载其他软件包，但是

magrittr

似乎被认为不安全，并且无论我尝试什么都会收到 403ed。

而且

magrittr

似乎是很多包都需要的核心包之一，所以没有它生活会很艰难。

我已取消勾选“选项”中的“使用安全方法进行 https 下载”选项。

我已经用

options(download.file.method = "wininet")

设置了我的下载方法

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

magrittr

zip URL 被 Zscaler 阻止。但其他包的 zip URL 不会被阻止。
