石墨/碳导入错误：没有模块命名字段

Question

我能够遵循几乎所有的指令here

但是当我到达时

[idf@node1 graphite]$ cd /opt/graphite/webapp/graphite/
[idf@node1 graphite]$ sudo python manage.py syncdb
Could not import graphite.local_settings, using defaults!
/opt/graphite/webapp/graphite/settings.py:244: UserWarning: SECRET_KEY is set to an unsafe default. This should be set in local_settings.py for better security
  warn('SECRET_KEY is set to an unsafe default. This should be set in local_settings.py for better security')
ImportError: No module named fields
[idf@node1 graphite]$ 

不知道为什么会出现这个错误？

我也尝试了这些说明，但它几乎在同一个地方挂断了

https://www.digitalocean.com/community/tutorials/how-to-keep-effective-historical-logs-with-graphite-carbon-and-collectd-on-centos-7

[idf@node1 graphite]$ sudo PYTHONPATH=/opt/graphite/webapp/ django-admin.py syncdb --settings=graphite.settings
/var/tmp/sclHwyLM6: line 8: PYTHONPATH=/opt/graphite/webapp/: No such file or directory
[idf@node1 graphite]$ 

如果我回显 PYTHONPATH，我会得到

[idf@node1 ~]$ echo $PYTHONPATH
/usr/lib64/python2.7/site-packages/openmpi
[idf@node1 ~]$ 

于是我创建了

/etc/profile.d/local_python.sh 

内容

PYTHONPATH="/opt/graphite/webapp/":"${PYTHONPATH}"
export PYTHONPATH

我创建了一个新的 shell，现在 echo 看起来是正确的

[idf@node1 graphite]$ echo $PYTHONPATH
/opt/graphite/webapp/:/usr/lib64/python2.7/site-packages/openmpi
[idf@node1 graphite]$ 

现在我跑了

[idf@node1 graphite]$ sudo django-admin.py syncdb --settings=graphite.settings

ImportError：无法导入设置“graphite.settings”（是否在 sys.path 上？）：没有名为 graphite.settings 的模块

Answer 1

当使用以下命令降级包 django-tagging (0.3.6) 时问题已解决：

pip uninstall django-tagging  
pip install 'django-tagging<0.4'

Answer 2

我能够通过替换这样的路径来使其工作

sudo django-admin.py syncdb --settings=graphite.settings

这样的路径

sudo /home/idf/anaconda/bin/django-admin.py syncdb --pythonpath /opt/graphite/webapp --settings graphite.settings 

Answer 3

@Peigong 正确解决了它。我会为问题添加解释。

django-tagging 0.4 需要新版本的 Django 1.7 或更高版本以及 Python 2.7 或更高版本。将 django-tagging 降级到 0.3.6 将适用于较旧的 Django，例如 Django 1.5

pip uninstall django-tagging
pip install django-tagging===0.3.6

或在 CM 中

python_pip "django-tagging" do
    version "0.3.6"
end
