我正在使用此链接制作一些docker-compose yml文件.在这个配置中,驱动程序的含义是什么:本地顶级卷？

volumes:
  esdata1:
    driver: local
  esdata2:
    driver: local

我正在尝试设置一个通过psycopg2使用PostgreSQL的Python应用程序,但该模块在导入时仍然失败.

ImportError: Permission denied

我已经在全局和virtualenv中使用pip安装了psycopg2

环境如下:( XP x86上的Cygwin)

Python 2.6.8 (unknown, Jun  9 2012, 11:30:32)
[GCC 4.5.3] on cygwin

导入模块:

[12:49:45] /usr/lib/python2.6/site-packages/psycopg2 $ python -c "import psycopg2"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python2.6/site-packages/psycopg2/__init__.py", line 67, in <module>
    from psycopg2._psycopg import BINARY, NUMBER, STRING, DATETIME, ROWID
ImportError: Permission denied

有问题的模块是_psycopg,即_psycopg.dll,如果我重命名它,就无法找到模块,正如预期的那样.

[12:50:01] /usr/lib/python2.6/site-packages/psycopg2 $ mv _psycopg.dll X_psycopg.dll
[13:00:53] /usr/lib/python2.6/site-packages/psycopg2 $ python -c "import psycopg2"
