Question

我试图在Ubuntu 14.04上从软件包安装CKAN（2.7.1）后安装“ckanext-spatial”。我跟着official tutorial。一切顺利，直到我运行以下命令：

pip install -r pip-requirements.txt

事实证明没有pip-requirements.txt，因此我将其更改为

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/

要解决此错误，我尝试升级setuptools和pip。他们都没有工作。

已更新：事实证明，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，但是我收到了一个新错误。

Answer 1

这里存在一些目录混淆，这就是为什么你没有看到pip-requirements.txt。

首先，您需要激活您的python环境：

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

然后教程的第1步：

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

然后你需要这样做：

cd ckanext-spatial

之前：

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

ckanext-spatial - “python setup.py egg_info”失败，错误代码为
