Python/ImportError:不支持按文件名导入

Question

我正在尝试将python文件导入我的应用程序,该文件是用python编写的.

我有以下代码:

import os
from os.path import basename

class specificClass:
    def dothing(self,path):
          runcommand = __import__("/root/"+ os.path.splitext(os.path.basename(path))[0]+ "/" + os.path.splitext(os.path.basename(path))[0] +"/sa/update.py")
          runcommand.main()

当我运行它时,它给我以下错误:

ImportError: Import by filename is not supported.

Answer 1

__import__你可以说,而不是做一个导入

import sys
sys.path.append(path) # this is where your python file exists
import update
