安装openstack-dashboard时出现的python compress command not found错误解决办法
httpd服务启动失败
# systemctl status httpd ● httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled) Drop-In: /usr/lib/systemd/system/httpd.service.d └─openstack-dashboard.conf Active: failed (Result: exit-code) since Fri 2016-10-14 16:13:27 CST; 25s ago Docs: man:httpd(8) man:apachectl(8) Process: 86591 ExecStartPre=/usr/bin/python /usr/share/openstack-dashboard/manage.py compress --force (code=exited, status=1/FAILURE) Process: 86581 ExecStartPre=/usr/bin/python /usr/share/openstack-dashboard/manage.py collectstatic --noinput --clear (code=exited, status=0/SUCCESS) Main PID: 82651 (code=exited, status=0/SUCCESS) Oct 14 16:13:27 bdc2 python[86591]: CommandError: An error occurred during rendering /usr/share/openstack-dashboard/openstack_dashboard/templates/_stylesheets.html: /bin/sh: django_pyscss.compressor.DjangoScssFilter: command not found Oct 14 16:13:27 bdc2 python[86591]: Found 'compress' tags in: Oct 14 16:13:27 bdc2 python[86591]: /usr/lib/python2.7/site-packages/horizon/templates/horizon/_conf.html Oct 14 16:13:27 bdc2 python[86591]: /usr/share/openstack-dashboard/openstack_dashboard/templates/_stylesheets.html Oct 14 16:13:27 bdc2 python[86591]: /usr/lib/python2.7/site-packages/horizon/templates/horizon/_scripts.html Oct 14 16:13:27 bdc2 python[86591]: Compressing...

执行上面状态中失败的命令会出现具体的错误信息
# /usr/bin/python /usr/share/openstack-dashboard/manage.py compress --force Found 'compress' tags in: /usr/lib/python2.7/site-packages/horizon/templates/horizon/_conf.html /usr/share/openstack-dashboard/openstack_dashboard/templates/_stylesheets.html /usr/lib/python2.7/site-packages/horizon/templates/horizon/_scripts.html Compressing... CommandError: An error occurred during rendering /usr/share/openstack-dashboard/openstack_dashboard/templates/_stylesheets.html: /bin/sh: django_pyscss.compressor.DjangoScssFilter: command not found
错误分析: python-django无法执行compress的命令,按照网上的说法修改文件中的compress
{% load compress %} {% compress css %} {% endcompress %}
将type='text/scss' 修改为type='text/x-scss' 或者type='text/css' ,重启httpd服务,服务依旧启动失败或者能够启动成功,但是查看状态依旧显示异常。
正确的解决办法: 修改django-pyscss的版本,2.0.2版本的才可以正常使用 默认安装的时候,会自动安装epel中的源,版本为1.0.5
# yum list|grep django-pyscss python-django-pyscss.noarch 1.0.5-2.el7 @epel # cd /usr/lib/python2.7/site-packages/ # ls |grep pyscss django_pyscss django_pyscss-1.0.5-py2.7.egg-info
把1.0.5版本去掉,使用pip安装2.0.2版本
# cd /usr/lib/python2.7/site-packages/ # mv django_pyscss-1.0.5-py2.7.egg-info django_pyscss-1.0.5-py2.7.egg-info_bak # pip install django-pyscss==2.0.2 # pip list|grep pyscss django-pyscss (2.0.2)
重启httpd服务
