Django：導入模塊

我試圖用Django應用程序控制一個覆盆子pi的LED。我寫了一個python腳本來設置LED的顏色，一切都是okey。但是，當我從我的views.py調用腳本我得到一個AttributeError：模塊沒有屬性。Django：導入模塊

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('')

在目錄「蘭普/靜態/蘭佩/腳本」我有三個文件：空初始化的.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]))

可以在'launcher.py'或'views.py'中使用回溯 – Pyrotecnix

編輯的文章，您可以嘗試'print（LED .__ file __）'來查看正在導入的'lampe'模塊？您可能會意外地將一個'static/lampe'文件夾或項目文件夾作爲一個包導入。 –

是'target = LED.setCouleur'正確嗎？你確定它不應該是'target = LED.setCouleur（）？通常，setter和getters是AFAIK的函數，但也許這是預期的。 – seanmus

的項目「蘭佩」是隱藏在蘭普/靜態/蘭佩的「lampe.py」名稱/腳本，因爲它是被python找到並在導入'lampe.py'模塊之前導入它。請重命名您的lampe.py並重試。
