如何將Peewee與scrapinghub一起使用

Question

我想使用peewee將數據保存到遠程計算機。 當我運行搜尋器時，發現以下錯誤，

File "/usr/local/lib/python2.7/site-packages/scrapy/commands/crawl.py", line 57, in run
    self.crawler_process.crawl(spname, **opts.spargs)
  File "/usr/local/lib/python2.7/site-packages/scrapy/crawler.py", line 163, in crawl
    return self._crawl(crawler, *args, **kwargs)
  File "/usr/local/lib/python2.7/site-packages/scrapy/crawler.py", line 167, in _crawl
    d = crawler.crawl(*args, **kwargs)

    self.scraper = Scraper(crawler)

    self.itemproc = itemproc_cls.from_crawler(crawler)
  File "/usr/local/lib/python2.7/site-packages/scrapy/middleware.py", line 58, in from_crawler
    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)
  File "/usr/local/lib/python2.7/site-packages/scrapy/utils/misc.py", line 44, in load_object
    mod = import_module(module)
  File "/usr/local/lib/python2.7/importlib/__init__.py", line 37, in import_module
    __import__(name)
  File "/app/__main__.egg/annuaire_agence_bio/pipelines.py", line 8, in <module>

exceptions.ImportError: No module named peewee

任何建議都值得歡迎。

您不能在Scrapinhub上安裝您自己選擇的模塊...您只能根據我的知識安裝MySQLDB。

在項目的主文件夾中創建一個名為scrapinghub.yml的文件，內容如下。

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

其中111149是我111149上的項目ID。

在同一目錄中創建另一個名為requirements.txt的文件。

然后將所需的模塊以及正在使用的版本號放入該文件中，如下所示：

MySQL-python==1.2.5

PS：我使用的是MySQLDB模塊，所以我提出了。
