scrapy运行过程中报错，ModuleNotFoundError: No module named 'pymongo'

Question

我直接运行单文件，并没有导入错误，此外，我单独在py文件中使用mongodb也正常，但是在scrapy项目中运行，会说导入失败，这是为什么？ import json import pymongo from scrapy.utils.project import get_project_settings class MyscrapyPipeline(object): def __init__(self): settings = get_project_settings() client = pymongo.MongoClient(host=settings['MONGODB_HOST'], port=settings['MONGODB_PORT']) db = client[settings['MONGODB_DBNAME']] self.mongo = db[settings['MONGODB_COLNAME']['taptap']] def process_item(self, item, spider): """ 处理数据 """ for k, v in item.items(): item[k] = ''.join(v.split()) if bool(type(v) is not list) else v self.mongo.insert_one(json.dumps(dict(item), ensure_ascii=False)) return item
