no module named req

错误：

Traceback (most recent call last):
  File "dingdang.py", line 11, in <module>
    from client import tts
  File "/home/youzinan/zhou/robot/dingdang-robot-master/client/tts.py", line 32, in <module>
    from . import diagnose
  File "/home/youzinan/zhou/robot/dingdang-robot-master/client/diagnose.py", line 10, in <module>
    import pip.req
ImportError: No module named req
 

解决方案：

方案1

直接升级pip无效

方案2

直接在原函数中把import改为直接添加代码函数

def parse_requirements(filename):
    """ load requirements from a pip requirements file """
    lineiter = (line.strip() for line in open(filename))
    return [line for line in lineiter if line and not line.startswith("#")]
