我正在尝试通过drush创建DKAN网站，而我目前在安装网站时遇到了一些问题。我已经下载了drush，dkan和mysql，并且mysql服务器当前正在使用版本mysql Ver 14.14 Distrib 5.7.13, for osx10.11 (x86_64) using EditLine wrapper运行。
说root@localhost的mysql密码是passw0rd。然后，从dkan / webroot目录中运行命令drush site-install dkan --db-url="mysql://root:passw0rd@localhost/dkandb"。
安装开始，“开始Drupal安装。这需要一段时间。”但是大约一分钟后，我得到以下异常：
exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1171 All parts of a PRIMARY KEY must be NOT NULL; if you need NULL in a key, use UNIQUE instead' in /Users/Nicholas/dkan/webroot/includes/database/database.inc:2204
以及25个项目的堆栈跟踪：

关于如何消除
SQLSTATE[42000]错误的任何想法？ 最佳答案
您正在使用哪个版本的DKAN？看来在panelizer模块上安装失败。您遇到的同一件事有一个问题：https://www.drupal.org/node/2659820
您可以尝试在那里直接应用更新。
仅供参考，如果您在https://github.com/NuCivic/dkan/issues上打开票证，您将获得DKAN团队的更多直接支持。
似乎DKAN需要更新到最新版本的panelizer才能获得适用于您的错误https://github.com/NuCivic/dkan/blob/7.x-1.x/drupal-org.make#L110的修复程序，他们应该在下一个版本中
