创建数据库表时出错 - CKAN

Question

我正在尝试在 Centos 6.8 上安装 CKAN 2.5.2

当我运行 paster db init -c /etc/ckan/default/development.ini

我收到错误

Traceback (most recent call last):

我关注了 wiki instructions

我卡在这一步了，不知道如何继续。

模块 html5lib 已导入并更新到最新版本。 Paster脚本在root账户下的virtualenv中执行。

此外，我运行将所有这些都放在 python2.6 中，因为这是 Centos 的默认设置。

一些附加信息

当我运行 python 并导入 html5lib 然后帮助 (html5lib) 我得到这个

>>> import html5lib
>>> help(html5lib)
Help on package html5lib:

NAME
    html5lib

FILE
    /usr/lib/python2.6/site-packages/html5lib/__init__.py

DESCRIPTION
    HTML parsing library based on the WHATWG "HTML5"
    specification. The parser is designed to be compatible with existing
    HTML found in the wild and implements well-defined error recovery that
    is largely compatible with modern desktop web browsers.

    Example usage:

    import html5lib
    f = open("my_document.html")
    tree = html5lib.parse(f)

这里没有消毒剂。我需要使用特定版本的 html5lib 吗？

有人能帮忙吗？

Answer 1

您似乎安装了 2 个 html5lib 副本。当您执行 help(html5lib) 时，它显示的是安装在用户的 python 目录（/usr/lib/python2.6/site-packages/）中的副本，而不是安装了 ckan（和漂白剂）的 virtualenv (/usr/lib/ckan/default/lib/python2.6/site-packages/)。所以去掉前者以避免混淆。

是的，我认为您的 html5lib 版本有误，因为当我提供帮助时，包内容中列出了消毒剂。

这是正确的版本（在撰写本文时 - 将来检查 requirements.txt 中的内容）：

$ pip freeze | grep html5lib
html5lib==0.9999999
