我需要传递的参数是之前格式化为字符串的列表,就像这样:

class MySpider(Spider):
name = "myS"
def __init__(self, arg1, arg2):
super(MySpider, self).__init__()
#Rest of the code
然而,当我运行它时,我遇到了这个错误:
Traceback (most recent call last):
File "C:/Users/ME/projects/script.py", line 207, in run
cmdline.execute("scrapy crawl myS -a arg1="+numbers+" -a data="+colors)

del argv[i]
