运行 Solr 时出错

Question

我正在尝试通过以下方式安装 Apache Solr for Plone集体.solr。

我已按照上述说明进行操作，并使用以下内容扩展了我的构建：

[buildout]
extends =
  buildout.cfg
  https://github.com/Jarn/collective.solr/raw/master/buildout/solr.cfg

[instance]
eggs += collective.solr

bin/buildout 运行良好，但是当我尝试bin/solr-instance fg

我收到以下错误：

Traceback (most recent call last):
  File "bin/solr-instance", line 114, in <module>
    start(False)
  File "bin/solr-instance", line 43, in start
    stdout=logfp, stderr=logfp).pid
  File "/usr/lib/python2.6/subprocess.py", line 633, in __init__
    errread, errwrite)
  File "/usr/lib/python2.6/subprocess.py", line 1139, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory
Graceful stop

我遗漏了什么或者做错了什么？
