我正在尝试在另一个运行 Ubuntu Server 14.04.1 的 VM 上使用 PostgreSQL 在 CentOS 6.6 上设置自己的wirecloud 实例。因此，我遵循了本指南，该指南运行良好，直到我进行了 django 配置。

每次我尝试运行 compress 语句时，我都会收到以下错误：

Compressing... /usr/local/venv/lib/python2.6/site-packages/scss/types.py:1065: FutureWarning: String got a bytes type 'platform' -- this will no longer be supported in pyScss 2.0
  .format(value)

data_ret['preferences'] = {preference['name']: cache_manager.get_variable_data(iwidget, preference['name']) for preference in iwidget_info['preferences']}

这是字典理解。它们是在 Python 2.7 中添加的。您正在运行 Python 2.6，因此您遇到了语法错误。
