根据http://docs.ckan.org/en/latest/maintaining/installing/install-from-source.html在 OSX 10.9 上本地安装 CKAN 。

我已经创建并激活了 python virtualenv，现在需要创建一个 CKAN 配置文件：

$ paster make-config ckan /etc/ckan/default/development.ini

输出如下（最后一行的 ImportError ）：

      ckan 2.2 from ~/ckan/lib/default/src/ckan

我不确定如何进行，有什么想法吗？

ImportError: No module named pylons.util看起来 Python 找不到 Pylons 包，这是 CKAN 依赖的 Python 包之一。想到了两种可能：

  1. 在运行 paste 命令之前，您是否激活了 CKAN virtualenv？~/ckan/default/bin/activate.

  2. 您是否已将 CKAN 依赖的 Python 包安装到您的 virtualenv 中？使用 virtualenv 激活运行pip install -r ~/ckan/default/src/ckan/requirements.txt

如果您激活 CKAN 虚拟环境然后运行pip freeze | grep pylons，这应该会告诉您是否在 virtualenv 中安装了 pylons。

Distribution already installed:终端输出顶部的 很奇怪。

我有同样的错误和稍微不同的解决方案：

  1. 使用后才出现错误sudo，所以我退出了它（sudo -k）
  2. 然后我收到以下错误：IOError: [Errno 13] Permission denied: '/etc/ckan/default/development.ini'
  3. 经过大量挖掘，我终于发现虽然 /etc/ckan 具有正确的权限，但它实际上是一个符号链接，~/ckan/etc并且该文件夹没有正确的权限
  4. 我跑了sudo chown -R `whoami` ~/ckan/etc，跟了上去paster make-config ckan /etc/ckan/default/development.ini
