Emacs C-c C-c 用于 python 代码

Question

我刚开始使用 emacs 作为 python 的 IDE。我激活了 pymode 和 Ropemacs。我的理解是我应该能够突出显示一个区域，然后使用 C-c C-c 将其发送到交互式终端。我需要其他软件包来完成此操作吗？

我得到的 C-c C-c 错误是：

Wrong type argument: integer-or-marker-p, nil

我还看到 this link 对此发表了声明，但这看起来不像是我的错误。

更新回答扎克

为了设置该变量，我进入了 emacs scratch 并这样做了：

(setq debug-on-error t)

然后M-x eval-region

（这是将其设置为 true 的正确方法吗？）

那么这就是我的调试器中出现的内容：

Debugger entered--Lisp error: (wrong-type-argument integer-or-marker-p nil)

显示的错误是由 python-mode.el 中的错误导致的，该错误已在主干中修复。 AFAIK 该错误仅在执行未保存的缓冲区时发生，因此首先保存缓冲区会使 C-c C-c 工作。

BTW py-execute-region RET 是 C-c |，而 C-c C-c 将始终发送整个缓冲区，无论现有区域如何。如果 C-c C-c 应该尊重一个区域，那可能值得一个功能请求。如果有兴趣，请在此处提交：

仍然是个人观点：将区域标记为这样的成本很高 - 例如。一件费力的事情，因为它需要一些注意力来定义边界权，而这在所涉及的问题本身上会花费更多。 Python 模式将通过提供几个执行什么命令来完成大量的工作。也许看看菜单“Python”，参见“执行...”部分和“更多...”按钮。以类似的方式，其他几个编辑应该会更容易。
