r - 错误 : package or namespace load failed for ‘gmm’ in dyn. load(file, DLLpath = DLLpath, ...): 无法加载共享对象

Question

我已经将R的版本上传到4.0.2(2020-06-22)。在我需要时安装 gmm 包后，我收到了以下消息。我还为其他软件包(如 TropFishR)获取了此消息。我有 Xcode 10.3 。我重新安装了 R studio 和 R 几次。非常感谢您抽出宝贵时间。

错误信息:

Error: package or namespace load failed for ‘gmm’ in dyn.load(file, DLLpath = DLLpath, ...):

Answer 1

问题是因为 Library not loaded:/usr/local/gfortran/lib/libgomp.1.dylib is missed.

为了解决这个问题，我去了this Github 发布页面，下载gfortran-10.2-Catalina.dmg，并安装。然后我终于可以在 R 中加载 gmm 包了。
