r - 更新 Pandas 后无法导入 rpy2.robjects "ValueError: The system "%s"不受支持。"

Question

我在 Windows 10 上运行 miniconda。我已经安装了 rpy2 并在过去使用它没有任何问题。最近我从 Pandas 版本 0.24.0 升级到 0.25.1。在发现它破坏了我一直在处理的自定义包之后，我决定将降级回 Pandas 0.24.0 版。完成所有这些之后，当我尝试使用以下方法导入 robjects 时:

import rpy2.robjects as ro

我收到此错误消息:

ValueError: The system "%s" is not supported.

当我尝试在 windows7 上使用 rpy2 时，这个问题发生在我身上。如果是这种情况，请确保遵循以下程序:

rpy2 install on windows 7

还要确保你这样做:

pip 安装 tzlocal
