听说 make 检测目标更新的原理是比较源文件和目标文件的修改时间，源文件后于目标文件则需要重新 make。
好像可以：
import os
import os.path
import subprocess
import logging
logger = logging.getLogger(__name__)
stream_handler = logging.StreamHandler()
logger.addHandler(stream_handler)
source_mtime = os.path.getmtime("test.py")
target_mtime = os.path.getmtime("[email protected]")
if source_mtime > target_mtime:
logger.info("need remake {}".format('[email protected]'))
proc = subprocess.Popen(
[
"python",
"test.py",
],
cwd=os.getcwd(),
)
print(" ".join(proc.args))
else:
print("nothing to remake")
@mashiro 确实，有点问题
