ImportError:没有名为_bsddb的模块

Question

我最近在升级matplotlib时遇到了一些问题，所以我最终通过brew在我的Mac (Sierra)上安装了不同版本的Python，然后卸载了它。然而，现在matplotlib可以工作(2.0.2)，但每当我运行一个以前可以工作的特定python脚本时，我都会得到一个以前没有的错误：

Traceback (most recent call last):
  File "sim.py", line 254, in <module>
    main()
  File "sim.py", line 118, in main
    db = shelve.open('.sim_balance', 'c')
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/shelve.py", line 243, in open
    return DbfilenameShelf(filename, flag, protocol, writeback)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/shelve.py", line 227, in __init__
    Shelf.__init__(self, anydbm.open(filename, flag), protocol, writeback)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/anydbm.py", line 84, in open
    mod = __import__(result)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/dbhash.py", line 7, in <module>
    import bsddb
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/bsddb/__init__.py", line 67, in <module>
    import _bsddb
ImportError: No module named _bsddb

根据我的在线搜索，这与我的brew安装的python干扰有关吗？我昨天还删除了/Library/Python/2.7/site-packages中的所有文件，这可能也是导致这一问题的原因。

我曾经尝试过自制的brew install berkeley-db，但后来pip install bsddb3出现了问题：

Terrys-MBP:site-packages Terry$ pip install bsddb3
Collecting bsddb3
  Using cached bsddb3-6.2.4.tar.gz
    Complete output from command python setup.py egg_info:
    Can't find a local Berkeley DB installation.
    (suggestion: try the --berkeley-db=/path/to/bsddb option)

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/m5/1fg5rnj11_9cz5pntlqlwzyc0000gn/T/pip-build-elBAFK/bsddb3/

编辑:已解决。安装了anaconda，通过conda install安装了bsddb，现在一切都正常了。
