如何在 scrapinghub 中使用 peewee

Question

我想使用 peewee 将我的数据保存到远程机器。当我运行我的爬虫时，我发现了以下错误，

File "/usr/local/lib/python2.7/site-packages/scrapy/commands/crawl.py", line 57, in run
    self.crawler_process.crawl(spname, **opts.spargs)

    return cls.from_settings(crawler.settings, crawler)
  File "/usr/local/lib/python2.7/site-packages/scrapy/middleware.py", line 34, in from_settings
    mwcls = load_object(clspath)

    __import__(name)
  File "/app/__main__.egg/annuaire_agence_bio/pipelines.py", line 8, in <module>

exceptions.ImportError: No module named peewee

欢迎提出任何建议。

您不能在 Scrapinhub 上安装您自己选择的模块...据我所知，您只能安装 MySQLDB。

在项目的主文件夹中创建一个名为scrapinghub.yml 的文件，内容如下。

projects:
  default: 111149
requirements:
  file: requirements.txt

111149 是我在 scrapinghub 上的项目 ID。

在同一目录中创建另一个名为 requirements.txt 的文件。

并把你需要的模块和你正在使用的版本号一起放在那个文件中，像这样，

MySQL-python==1.2.5

PS：我使用的是 MySQLDB 模块，所以我把它放了。
