在 python 终端中导航
我想要在我的 Mac 上有一个 64 位 python 解释器，所以我必须从源代码重建。然而，使用我自己的自定义构建解释器，当我尝试从 shell 内部运行解释器进行导航时，我遇到了问题。在 bash shell 中输入 python 会产生熟悉的结果：
Python 2.6.3 (r263:75183, Oct 23 2009, 14:23:25)
[GCC 4.2.1 (Apple Inc. build 5646) (dot 1)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

但是，当我尝试使用左箭头和右箭头导航时，我得到奇怪的字符：
Python 2.6.3 (r263:75183, Oct 23 2009, 14:23:25)
[GCC 4.2.1 (Apple Inc. build 5646) (dot 1)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> ^[[A^[[A^[[A^[[D^[[C^[[C^[[A^[[B^[[D^[[C
这在 Apple 的默认解释器中不会发生。
是什么原因造成的？我该如何修复它？
I want a 64-bit python interpreter on my Mac so I had to rebuild from source. However, with my own custom build interpreter I run into issues when I try to navigate when I run the interpreter from inside a shell. Typing python into the bash shell results in the familiar:
Python 2.6.3 (r263:75183, Oct 23 2009, 14:23:25)
[GCC 4.2.1 (Apple Inc. build 5646) (dot 1)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

However, when I try to navigate with left-arrow and right-arrow, I get weird characters:
Python 2.6.3 (r263:75183, Oct 23 2009, 14:23:25)
[GCC 4.2.1 (Apple Inc. build 5646) (dot 1)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> ^[[A^[[A^[[A^[[D^[[C^[[C^[[A^[[B^[[D^[[C
This does not occur in Apple's default interpreter.
What is causing this? How can I fix it?

听起来您的自定义构建不包括 readline。应该是一个简单的配置更改和重建，请检查 此处了解更多信息。
Sounds like your custom build didn't include readline. Should be a simple config change and rebuild, check here for more info.
从此处安装 GNU readline 库，并重建 python 修复了问题。
Installing the GNU readline library from here, and rebuilding python fixes the problem.
