Scrapyd 部署时权限被拒绝

Question

我刚接触Scrapyd，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，它返回了

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-default文件中把 debug=on 打开后，错误变成了

root@robert-GA-870A-UD3:/home/feed/Desktop/feed/scrapers# scrapy deploy default
Packing version 1407875943

这个错误可能会让人有点困惑。试着在你的项目文件夹里运行（也就是setup.py文件所在的目录）：

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

这样做基本上和scrapy deploy的效果是一样的，但会显示更多的信息（你可以把tmp里的目录名字改成其他的，这里只是举个例子，scrapy在'-'后面会生成一些随机的名字）。

在我的情况下，问题出在我项目里的构建目录的权限上（scrapy deploy无法删除里面的旧文件），所以我直接删除了这个目录，反正它是自动生成的。
