部署时拒绝Scrapyd权限

Question

我对Scrapyd非常陌生，正在尝试部署。我在Ubuntu 12.04上运行，并安装了Scrapyd的ubuntu版本。当我运行scrapy deploy default -p pull_scrapers时，它返回

Packing version 1407616523
Deploying to project "pull_scrapers" in http://localhost:6800/addversion.json
Server response (200):
{"status": "error", "message": "[Errno 13] Permission denied:'/var/lib/scrapyd/eggs/pull_scrapers'"}


Any idea why this would be? I looks to be a credentials problem, but so far as I know it doesn't have any. Any help is appreciated.

编辑：

在conf.d/000- debug=on文件中设置默认设置后，错误是

这个错误可能有一些误导性。尝试从项目内部运行( setup.py所在的目录)：

python setup.py clean -a bdist_egg -d /tmp/scrapydeploy-8NnURF

这实际上会做与scrapy deploy相同的事情，但它会显示更多的输出(你可以在tmp中更改目录的名称，例如，scrapy会在‘-’后随机生成一些东西)。

在我的例子中，我的项目中build目录的权限有问题(scrapy deploy无法删除里面的旧文件)，所以我删除了该目录，因为它无论如何都是自动生成的。

附言:我会留下一个评论，但我没有足够的声誉。
