错误：dyn.load(file, DLLpath = DLLpath, ...) 中的“gmm”的包或命名空间加载失败：无法加载共享对象

Question

我已将 R 版本上传到 4.0.2 (2020-06-22)。\n安装 gmm 包后，当我需要它时，我收到以下消息。我还为其他软件包（例如 TropFishR）采纳了此消息。我有 Xcode 10.3 。我重新安装了R studio和R几次。非常感谢您的宝贵时间。

Answer 1

问题的产生是因为Library not loaded: /usr/local/gfortran/lib/libgomp.1.dylib错过了。

为了解决这个问题，我访问了这个Github 发布页面，下载gfortran-10.2-Catalina.dmg并安装了它。然后我终于可以gmm在 R 中加载包了。
