安装 readline 模块后 Python 3.6.1 崩溃 [英] Python 3.6.1 crashed after readline module installed

问题描述

我已经从源代码编译并安装了 Python 3.6.1，然后运行 ​​sudo pip3 install readline 来安装 readline 模块.但是当我启动 Python shell 时，无论我输入什么，它都会崩溃:

I've compiled and installed Python 3.6.1 from source code, and run sudo pip3 install readline to install the readline module. But when I start the Python shell, it crashes whatever I enter:

Python 3.6.1 (default, Mar 25 2017, 13:40:56)

这是怎么回事?我使用的是 Ubuntu 16.04.

What's the matter here? I'm using Ubuntu 16.04.

推荐答案

改为尝试 pip install gnureadline.并删除readline:pip uninstall readline.

Try pip install gnureadline instead. And remove readline: pip uninstall readline.

如 pypi 上的 gnureadline 包页面所述.org:

某些平台(例如 macOS)未安装 GNU readline

Some platforms, such as macOS, do not ship with GNU readline installed

该模块[捆绑]了标准 Python readline 模块和 GNU readline 源代码，后者被编译并静态链接到它.最终结果是一个易于安装且不需要额外共享库的包.

This module [bundles] the standard Python readline module with the GNU readline source code, which is compiled and statically linked to it. The end result is a package which is simple to install and requires no extra shared libraries.

所以 gnureadline 包带有编译和链接所需的代码，而 内置 python readline 库 依赖于已经安装在系统上的 GNU readline(或替代方案).

So the gnureadline package comes with the required code compiled and linked whereas the builtin python readline library relies on GNU readline (or an alternative) to be installed on the system already.
