在 CentOS7 上从源代码编译 Python3.4 时无法构建可选模块 readline 和 _curses

【问题描述】：

在 CentOS 7 上从源代码编译 Python 3.4.3 时，README 指示运行

./configure
make
make test
sudo make install

第二步，make，我明白了

Python build finished successfully!
The necessary bits to build these optional modules were not found:
_bz2                  _curses               _curses_panel
_dbm                  _gdbm                 _lzma
_sqlite3              _ssl                  _tkinter
readline              zlib
To find the necessary bits, look in setup.py in detect_modules() for the module's name.

但是 setup.py 的源代码中没有任何内容表明要做什么？好像我已经有了必备的包？

$ sudo yum install readline
...
Package readline-6.2-10.el7.x86_64 already installed and latest version
Nothing to do

如何获取 python 3 的 readline 模块？

【问题讨论】：

标签： python python-3.x centos readline

【解决方案1】：

安装readline-devel 包

$ sudo yum install readline-devel
[...]
Installed:
  readline-devel.x86_64 0:6.2-10.el7

Dependency Installed:
  ncurses-devel.x86_64 0:5.9-14.20130511.el7_4

Dependency Updated:
  ncurses.x86_64 0:5.9-14.20130511.el7_4   [...]

Complete!

然后重新运行make

$ make
[...]
Python build finished successfully!
The necessary bits to build these optional modules were not found:
_bz2                  _dbm                  _gdbm
_lzma                 _sqlite3              _ssl
_tkinter              zlib

现在readline 和_curses 模块都已安装，并且缺少模块列表。

我从这个问题的答案中得到了提示：yum showing readline installed but readline command not working

事实证明，这种模式适用于其他缺失的包。 ssl 需要 openssl-devel 包，zlib 需要 zlib-devel。
