Exception 安装ckanext archiver时没有名为芹菜的模块

我正在使用CKAN作为我的开放式数据门户，并尝试按照上的说明安装Archiver扩展。然而，在我的ckan配置文件中启用了archiver之后，我遇到了这个无法解决的错误

如果有人知道如何解决这个问题，我将不胜感激。谢谢。

在使用virtualenv时，不要调用

sudo pip install

，只要

pip install

我在执行时遇到了一些问题：

pip install -e git://github.com/okfn/ckanext-archiver.git#egg=ckanext-archiver

结果是

no matches found: git://github.com/okfn/ckanext-archiver.git#egg=ckanext-archiver

但下面的命令效果很好：

cd /tmp/
git clone git://github.com/okfn/ckanext-archiver.git
pip install -e ./ckanext-archiver
pip install -r ckanext-archiver/pip-requirements.txt

非常感谢，你的命令有效。我按照如下方式安装了它：

芹菜是为我完全安装的吗？对不起，我没有使用挂架的经验，因此无法帮助您解决这个错误。好主意是在谷歌上搜索挂架/贴纸/芹菜贴士，或者就你的新问题单独发布问题。谢谢你的建议！我是stackoverflow的新手。请签出并重试。
