加载 rpy2 时出现 Jupyter OSError 0x7e

Question

我在 Windows 10 上，我有一个新安装的 Anaconda Python 3.7 64 位，出于某些原因，我想在我的 D: 驱动器上运行我的 jupiter 笔记本。然后我打开我的 jupyter 命令，并在启动 jupyter notebook 之前将自己放在 D: 中。当我想加载 rpy2 时，我遇到了这个问题：

%load_ext rpy2.ipython

OSError: cannot load library 'C:\Program Files\R\R-3.6.1\bin\x64\R.dll': error 0x7e

我肯定知道这是因为我的笔记本在不同的硬盘上运行。我试图将 R 目录添加到我的 Windows 路径中，但它没有改变任何东西。

我怎样才能在我的驱动器 D: 上运行我的笔记本而不会出现这些问题？

谢谢你，
