python - 文件传送器错误 - UnboundLocalError : local variable 'classname' referenced before assignment

Question

我正在使用 fileconbayor 形式 https://github.com/wimleers/fileconveyor

但是当我运行脚本时出现以下错误。

Traceback (most recent call last):
File "arbitrator.py", line 1185, in <module>
run_file_conveyor()
File "arbitrator.py", line 1168, in run_file_conveyor
arbitrator = Arbitrator(os.path.join(FILE_CONVEYOR_PATH, "config.xml"), rest
art)
File "arbitrator.py", line 142, in __init__
transporter_class = self._import_transporter(transporter_name)
File "arbitrator.py", line 1162, in _import_transporter
self.logger.error("The Transporter module '%s' was found, but its Transporte
r class '%s' could not be found."  % (module_name, classname))
UnboundLocalError: local variable 'classname' referenced before assignment
[root@af-server fileconveyor]#

这是仲裁者.py 第 142 行的代码

   # Verify that all referenced transporters are available.
    transporters_not_found = 0
    for server in self.config.servers.keys():
        transporter_name = self.config.servers[server]["transporter"]
        transporter_class = self._import_transporter(transporter_name)
        if not transporter_class:
            transporters_not_found += 1
    if transporters_not_found > 0:
        raise TransporterAvailabilityTestError("Consult the log file for details")

以及第 1162 行的代码

transporter_class = None
    module = None
    alternatives = [transporter]
    default_prefix = 'transporters.transporter_' # Not  'fileconveyor.transporters.transporter_'!
    if not transporter.startswith(default_prefix):
        alternatives.append('%s%s' % (default_prefix, transporter))
    for module_name in alternatives:
        try:
            module = __import__(module_name, globals(), locals(), ["TRANSPORTER_CLASS"], -1)
        except ImportError:
            pass
    if not module:
        msg = "The transporter module '%s' could not be found." % transporter
        if len(alternatives) > 1:
            msg = '%s Tried (%s)' % (msg, ', '.join(alternatives))
        self.logger.error(msg)
    else:
        try:
            classname = module.TRANSPORTER_CLASS
            module = __import__(module_name, globals(), locals(), [classname])
            transporter_class = getattr(module, classname)
        except AttributeError:
            self.logger.error("The Transporter module '%s' was found, but its Transporter class '%s' could not be found."  % (module_name, classname))
    return transporter_class

这是该文件的完整代码

当我安装 fileconveyor 或按照指南 INSTALL.txt 时，我遇到了同样的错误。看起来有一些 Unresolved 依赖关系。尝试用以下方法解决:

pip install django-cumulus==1.0.10
