我正在尝试通过 buildroot 安装 python 2.7 安装 subprocess32 。它似乎安装正确,但当我将其导入嵌入式系统时,出现错误:
>>> import subprocess32
/usr/lib/python2.7/site-packages/subprocess32.py:472: RuntimeWarning: The _posixsubprocess module is not being used. Child process reliability may suffer if your pro
gram uses threads.
"program uses threads.", RuntimeWarning)
按照这条路径,我尝试导入 _posixsubprocess
import _posixsubprocess
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: dynamic module does not define init function (init_posixsubprocess)
subprocess32 似乎有它自己的版本,但在这种情况下不起作用?
这是我的制作文件:
#############################################################

SUBPROCESS32_VERSION = 3.2.7
SUBPROCESS32_SOURCE = subprocess32-$(SUBPROCESS32_VERSION).tar.gz

有一个类似的帖子是关于这个的Python 错误 _posixsubprocess 模块未使用 https://stackoverflow.com/questions/12508243/python-error-the-posixsubprocess-module-is-not-being-used然而答案是评论中的一个链接,该链接已失效。对我的问题有什么想法吗?

This is a backport of the subprocess standard library module from

It includes bugfixes and some new features. On POSIX systems it is
