安裝openstack-dashboard時出現的python compress command not found錯誤解決辦法

httpd服務啟動失敗

# systemctl status httpd ● httpd.service - The Apache HTTP ServerLoaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled)Drop-In: /usr/lib/systemd/system/httpd.service.d└─openstack-dashboard.confActive: failed (Result: exit-code) since Fri 2016-10-14 16:13:27 CST; 25s agoDocs: 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...

Oct 14 16:13:27 bdc2 systemd[1]: Unit httpd.service entered failed state. Oct 14 16:13:27 bdc2 systemd[1]: httpd.service failed.

執行上面狀態中失敗的命令會出現具體的錯誤信息

# /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

錯誤分析： python-django無法執行compress的命令，按照網上的說法修改文件中的compress

{% load compress %}{% compress css %} <link href='{{ STATIC_URL }}dashboard/scss/horizon.scss' type='text/scss' media='screen' rel='stylesheet' /> {% endcompress %}

將type='text/scss' 修改為type='text/x-scss' 或者type='text/css' ,重啟httpd服務，服務依舊啟動失敗或者能夠啟動成功，但是查看狀態依舊顯示異常。

正確的解決辦法： 修改django-pyscss的版本，2.0.2版本的才可以正常使用 默認安裝的時候，會自動安裝epel中的源，版本為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安裝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)

重啟httpd服務
