Question

基于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）：

Distribution already installed:
      ckan 2.2 from ~/ckan/lib/default/src/ckan
    Traceback (most recent call last):
      File "/usr/lib/ckan/default/bin/paster", line 9, in <module>

        from pylons.util import PylonsInstaller
    ImportError: No module named pylons.util

我不确定如何继续，任何想法？

Answer 1

ImportError: No module named pylons.util看起来Python无法找到Pylons包，它是CKAN所依赖的Python包之一。我想到了两种可能性：

在运行paster命令之前，您是否激活了CKAN virtualenv？ ~/ckan/default/bin/activate。
您是否已将CKAN所依赖的Python软件包安装到您的virtualenv中？随着virtualenv激活了运行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，这应该告诉您是否在virtualenv中安装了pylons。

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

Answer 2

我遇到了同样的错误和一个稍微不同的解决方案：

仅在使用sudo后才出错，所以我离开了它（sudo -k）
然后我收到以下错误：IOError: [Errno 13] Permission denied: '/etc/ckan/default/development.ini'
经过深入挖掘后，我终于发现，虽然/ etc / ckan具有正确的权限，但它实际上是~/ckan/etc的符号链接，并且该文件夹没有正确的权限
我跑了sudo chown -R `whoami` ~/ckan/etc并跟进paster make-config ckan /etc/ckan/default/development.ini

CKAN安装：贴纸错误
