Question

我正在尝试使用gganiminate库，当我调用gganimate :: gganimate（myplot）时，我遇到了问题。该问题似乎与依赖库magick有关。

当我调用该函数时，我收到以下警告：

    gganimate::gganimate(p)

1: running command 'C:\WINDOWS\system32\cmd.exe /c convert --version' had status 4
2: In find_magic() : ImageMagick not installed yet!
 In im.convert(img.files, output = path.expand(movie.name),  ... :
  Please install ImageMagick first or put its bin path into the system PATH variable

所以我尝试单独安装magick。我在客户端的计算机上，所以从github安装软件包需要我提供信息以通过防火墙。我已成功使用相同的技术从github安装了其他库。然而，magick似乎正在碰到其他问题。下面是我的代码和错误：

devtools::install_github("ropensci/magick",httr::set_config(httr::use_proxy("xx.xxx.xx.xx",xxxx)))

我想我的防火墙详情可能没有传递到：curl::curl_download(sprintf("https://github.com/rwinlib/imagemagick%s/archive/v%s.zip",...)

网络安全对我来说是一个黑盒子，所以我不确定还有什么可以尝试，或者我是否正确诊断问题。任何帮助将不胜感激！

在防火墙后面安装ropensci / magick
