我阅读了一些关于连接 Mysql 和 scrapinghub 部署脚本的线程。他们建议更改 *.yml 文件并添加需求 txt。该解决方案几天前有效。现在它没有。

在此处输入图像描述

这是来自 Shub Deploy 的错误。

是SH改变了smth还是我错了？

1）你应该写MySQL-python==1.2.5在你的requirements.txt文件中，这就是我所拥有的，我的项目运行良好。

然后我像这样使用MYSQL

import MySQLdb

conn = MySQLdb.connect(user=DB_CREDS['user'], passwd=DB_CREDS['pass'], db=DB_CREDS['db'], host=DB_CREDS['host'], charset="utf8", use_unicode=True)

cursor = MySQLdb.cursors.DictCursor(conn) 

conn.autocommit(True)

cursor.execute("SELECT myColumn FROM table_name")

for row in self.cursor.fetchall():
    print row['myColumn']

2）在再次部署之前删除build/和文件夹。project.egg-info/

3） 确保你的scrapinghub.yml文件看起来像这样

projects:
  default: 123213213
requirements_file: requirements.txt

得到同样的问题。

蟒蛇：3.9.6点：21.1.3 shub：2.13.0

// scrapyinghub.yml
projects:
  default: 70449

requirements_file: requirements.txt

// requirements.txt
pip==21.1.3

更新

指定scrapy-stack然后部署成功。

projects:
  default: 70449

stack: scrapy:1.3-py3

$ python -m shub deploy
