我试图从我的python代码连接到redshift.我的点子安装:

psycopg2==2.6.1
redshift-sqlalchemy==0.4.1
SQLAlchemy==1.0.9

我的虚拟机有:

libpq-dev
python-psycopg2

但我还是得到了

 engine = create_engine('redshift+psycopg2://{}:{}@{}'.format(username, password, url))
  File "/opt/project/env/local/lib/python2.7/site-packages/sqlalchemy/engine/__init__.py", line 386, in create_engine
    return strategy.create(*args, **kwargs)
  File "/opt/project/env/local/lib/python2.7/site-packages/sqlalchemy/engine/strategies.py", line 51, in create
    entrypoint = u._get_entrypoint()
  File "/opt/project/env/local/lib/python2.7/site-packages/sqlalchemy/engine/url.py", line 131, in _get_entrypoint
    cls = registry.load(name)
  File "/opt/project/env/local/lib/python2.7/site-packages/sqlalchemy/util/langhelpers.py", line 205, in load
    (self.group, name))
NoSuchModuleError: Can't load plugin: sqlalchemy.dialects:redshift.psycopg2

使用相同的配置,我可以从我的笔记本电脑(mac)运行,但在Linux上,我想有些软件包仍然缺失？任何建议将不胜感激,谢谢!
