在macOS上将dbm.gnu用于Python 3.6.8时遇到一些问题。我已经在conda的Python虚拟环境中安装了gdbm ...，但是在尝试调用dbm.gnu时出现以下错误消息：
---------------------------------------------------------------------------

---> 91 "available".format(result))
92 else:
93 mod = _modules[result]
error: db type is dbm.gnu, but the module is not available
有什么可靠的方法可以使它工作？我可以通过从astropy调用
cache = False时通过设置download_file来关闭缓存...但是我真的想设置cache = True。任何帮助将非常感激。 最佳答案
因此，我最终做了一些不可取的但可行的工作，那就是将“ /anaconda3/envs/py36-stable/lib/python3.6/dbm/gnu.py”中的唯一一行更改为
from _gdbm import *
至
from _dbm import *
...对我来说成功了。
