Scrapy顺序执行多个爬虫 有两种方式：

第一种：bat方式运行

        新建bat文件 

cd C:\python_web\spiders\tiktokSelenium & C: & scrapy crawl spider1 & scrapy crawl spider2 & scrapy crawl spider3 & scrapy crawl spider4

第二种：

使用subprocess按照顺序执行多个爬虫，新建一个start.py文件，输入一下内容，

def crawl_work():
    subprocess.Popen('scrapy crawl spider1', shell=True).wait()
    subprocess.Popen('scrapy crawl spider2', shell=True).wait()
    subprocess.Popen('scrapy crawl spider3', shell=True).wait()
    subprocess.Popen('scrapy crawl spider4', shell=True).wait()
if __name__ == '__main__':
    crawl_work()

然后 

cd C:\python_web\spiders\tiktokSelenium & C: & python ./start.py
