保存从setup.py生成的安装日志

在setup()调用该函数之前，请重定向sys.stdout（并重定向sys.stderr到日志文件。）

确保将stdout（和stderr）还原为它们的默认引用，并同时打印日志文件的内容stdout。

您的setup.py应该如下所示：

from setuptools import setup, find_packages
import sys

stdout = sys.stdout
stderr = sys.stderr

log_file = open('log', 'w')
sys.stdout = log_file
sys.stderr = log_file

setup ( 
        ...  ,
        ...
      )

# Make sure to close the log file. You could also use with to surround the setup()
# To ensure log file is closed in the event of exception.
log_file.close()

sys.stdout = stdout
sys.stderr = stderr

with open('log', 'r') as log_file:
    sys.stdout.write(log_file.read())
