python - 导入 pymorphy2 时出现异常

Question

我已经使用 pip 安装了 pymorphy2:

Requirement already satisfied (use --upgrade to upgrade): pymorphy2 in /usr/local/lib/python2.7/site-packages
Requirement already satisfied (use --upgrade to upgrade): docopt>=0.6 in /usr/local/lib/python2.7/site-packages (from pymorphy2)
Requirement already satisfied (use --upgrade to upgrade): pymorphy2-dicts<3.0,>=2.4 in /usr/local/lib/python2.7/site-packages (from pymorphy2)

但是当我试图在 Python 交互式 shell 中导入这个库时，我得到了这个:

>>> import pymorphy2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/site-packages/pymorphy2/__init__.py", line 3, in <module>
    from .analyzer import MorphAnalyzer
  File "/usr/local/lib/python2.7/site-packages/pymorphy2/analyzer.py", line 10, in <module>
    from pymorphy2 import opencorpora_dict
  File "/usr/local/lib/python2.7/site-packages/pymorphy2/opencorpora_dict/__init__.py", line 4, in <module>
    from .storage import load_dict as load
  File "/usr/local/lib/python2.7/site-packages/pymorphy2/opencorpora_dict/storage.py", line 24, in <module>
    from pymorphy2.utils import json_write, json_read
  File "/usr/local/lib/python2.7/site-packages/pymorphy2/utils.py", line 5, in <module>
    import bz2
ImportError: No module named bz2

好的，没问题:

sudo apt-get install libbz2-dev

最后:

在我的案例中，如何解决与 python 版本的冲突？

看起来您需要为 python 2.6 创建一个新的符号链接(symbolic link)。

ln -sf /usr/bin/python2.6 /usr/bin/python
