ckanext SPATICAL-“；python setup.py egg“u info”；失败，错误代码为

在从Ubuntu14.04的包中安装了CKAN（2.7.1）之后，我正在尝试安装“ckanext spatial”。我跟着火车走。在我执行以下命令之前，一切都很顺利：

pip install -r pip-requirements.txt

原来没有pip-requirements.txt，所以我把它改为

pip install --ignore-installed -r requirements.txt

我得到的错误是：

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-V6w2Vm/psycopg2/

为了解决这个错误，我尝试升级setuptools和pip。他们两个都不工作

更新：原来默认情况下，ckanext spatial安装在src文件夹下

(default) ubuntu@ckan-ubuntu1404-xlarge:/usr/lib/ckan/default/src$ ls
ckan  ckanext-spatial

现在，我可以找到pip-requirements.txt文件，但我发现了一个新错误

这里有一些目录混乱，这就是为什么您没有看到

pip requirements.txt

首先，您需要激活python环境：

. /usr/lib/ckan/default/bin/activate

然后，本教程的步骤1：

pip install -e "git+https://github.com/okfn/ckanext-spatial.git#egg=ckanext-spatial"

然后你需要做：

cd ckanext-spatial

在执行之前：

pip install --ignore-installed -r requirements.txt

谢谢，我回到src文件夹后找到了这个文件夹。但是，我仍然在pip install-r pip-requirements中遇到了一个错误。txt结果表明，我需要切换到虚拟环境之外的root用户并再次运行该命令。这听起来像是由于您以前在将python软件包安装到此virtualenv中时使用了sudo或root用户造成的。一旦你用过它，每次你都要用它。在这种情况下，我建议您删除virtualenv/usr/lib/ckan/default，并按照说明重新安装python模块，即针对ckan、扩展及其需求。
