我通过以下2个链接在ubuntu 16.04上安装了OpenStack newton和Tacker https://docs.openstack.org/newton/install-guide-ubuntu/

https://docs.openstack.org/developer/tacker/install/manual_installation.html

当我打开GUI时，我收到以下错误

Answer 1

首先，使用find /usr -name "security_group_rules.py"检查文件是否存在，通常可能在路径/usr/lib/python2.7/dist-packages/novaclient/v2/

中

如果文件存在，请检查python2.7包搜索路径，如下所示 enter image description here

确保文件路径位于包搜索路径

中

其次，检查路径/usr/local/lib/python2.7/dist-packages/，此路径可能具有相同的目录novaclient/v2/，这可能是导致错误的根本原因，当python搜索包时，它首先检查这个目录

您可以mv /usr/local/lib/python2.7/dist-packages/novaclient /usr/local/lib/python2.7/dist-packages/novaclient-old，或者只删除/usr/local/lib/python2.7/dist-packages/novaclient目录

最后，casuse这个错误是apt install而pip install已经在不同的路径中安装了类似的包。
