Question

我正在尝试使用Django应用程序中的覆盆子pi控制LED。我写了一个python脚本来设置LED的颜色，一切都很好。但是，当我从views.py调用脚本时，我得到了一个AttributeError：模块没有属性。

Views.py

import sys, os
PROJECT_DIR = os.path.dirname(os.path.abspath(__file__))
sys.path.append(os.path.join(PROJECT_DIR, 'static/lampe/scripts'))
import launcher, lampe

"""Vue utilisee pour appliquer une couleur"""
class Appliquer_couleur(View):
  def get(self, context, **reponse_kwargs):
    print(self.kwargs['pk'])
    couleur_serialized = CouleurSerializer(Couleur.objects.get(pk=self.kwargs['pk']))
    launcher.launch(couleur_serialized.data['code'])
    return HttpResponse('')

在目录“lampe / static / lampe / scripts”中我有三个文件：一个空的 init .py，lampe.py和launcher.py

Lampe.py

import sys
import RPi.GPIO as GPIO
def setCouleur(arg1):
  ..

Launcher.py

import sys, os
from multiprocessing import Process

import lampe as LED

def launch(arg1):
  try:
    process = Process(target=LED.setCouleur, args=(arg1,))
    process.start()
    process.join()
  except KeyboardInterrupt:
    pass

if __name__== "__main__":
  sys.exit(launch(sys.argv[1]))

您的项目名称“lampe”隐藏了lampe / static / lampe / scripts中的“lampe.py”，因为它是由python发现并在导入'lampe.py'模块之前导入它。请重命名你的lampe.py并重试。
