BuildVersion:	18A391

Error info:

  File "/usr/local/Cellar/python@2/2.7.15/Frameworks/Python.framework/Versions/2.7/lib/python2.7/shelve.py", line 227, in __init__
    Shelf.__init__(self, anydbm.open(filename, flag), protocol, writeback)

    import _bsddb
ImportError: No module named _bsddb

修正方式：

将dbhash.py 这个文件里import bsddb 改为 import bsddb3 as bsddb，我virutalenv的dbhash文件位置在:

/usr/local/Cellar/python@2/2.7.15/Frameworks/Python.framework/Versions/2.7/lib/python2.7/dbhash.py

try:
    #import bsddb
    import bsddb3 as bsddb
except ImportError:
    # prevent a second import of this module from spuriously succeeding
    del sys.modules[__name__]
    raise
