如何获取 Python 编译时使用的选项列表?

2022-01-13 00:00:00 python compilation packages

问题描述

您可以通过多种方式编译 Python.我想知道我的 Python 是用哪些选项编译的.

You can compile Python in various ways. I'd like to find out with which options my Python was compiled.

具体用例:我的 Python 是用 readline 编译的吗?我知道我可以通过import readline"看到这一点,但我想查看我的 Python 二进制文件的编译设置列表.

Concrete use-case: was my Python compiled with readline? I know I can see this by doing "import readline", but I'd like to see a list of compilation setting for my Python binary.

我是指 Python 可执行文件,不是我自己编写的源代码.

I mean the Python executable and not source code written by myself.


解决方案

有模块可以查看系统配置

There is a module to see the system config

import sysconfig
print(sysconfig.get_config_vars())

它还提供了一个接口来获取单个变量.

It offers an interface to get individual variables as well.

sysconfig.get_config_var('HAVE_LIBREADLINE')

也可以通过 shell 访问:

It is also accessible via shell:

python3 -m sysconfig | less

python2.7之前必须使用

before python2.7, you have to use

import distutils.sysconfig
print distutils.sysconfig.get_config_vars()
