Question

当我在Anaconda的python发行版中尝试import brian2时，我收到此错误消息：

>> import brian2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named brian

>>> import brian2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "//anaconda/lib/python2.7/site-packages/brian2/__init__.py", line 37, in <module>
    from pylab import *
  File "//anaconda/lib/python2.7/site-packages/pylab.py", line 1, in <module>
    from matplotlib.pylab import *
  File "//anaconda/lib/python2.7/site-packages/matplotlib/__init__.py", line 1131, in <module>
    rcParams = rc_params()

  File "//anaconda/lib/python2.7/site-packages/matplotlib/__init__.py", line 1100, in rc_params_from_file
    config_from_file = _rc_params_in_file(fname, fail_on_error)
  File "//anaconda/lib/python2.7/site-packages/matplotlib/__init__.py", line 1018, in _rc_params_in_file
    with _open_file_or_url(fname) as fd:
  File "//anaconda/lib/python2.7/contextlib.py", line 17, in __enter__
    return self.gen.next()
  File "//anaconda/lib/python2.7/site-packages/matplotlib/__init__.py", line 1000, in _open_file_or_url
    encoding = locale.getdefaultlocale()[1]
  File "//anaconda/lib/python2.7/locale.py", line 543, in getdefaultlocale
    return _parse_localename(localename)
  File "//anaconda/lib/python2.7/locale.py", line 475, in _parse_localename
    raise ValueError, 'unknown locale: %s' % localename
ValueError: unknown locale: UTF-8

我不明白为什么？是否与matplotlib和pylab有关？

Answer 1

根据http://anaconda.org/brian-team/brian2

anaconda的安装是

conda install -c http://conda.anaconda.org/brian-team brian2

Answer 2

这是OSX的一个错误，因为他们没有将他们的本地env变量设置为标准值：

正如@msw在评论中所说，修复是

export LANG=en_US.UTF-8

在你的bashrc中

。

另见：

https://github.com/matplotlib/matplotlib/issues/5420 https://github.com/bempp/bempp/issues/260 https://github.com/matplotlib/matplotlib/issues/5919 https://github.com/pydata/pandas/issues/11608 https://github.com/pydata/pandas/issues/11694

https://github.com/matplotlib/matplotlib/pull/5931是一个建议修复。这应该是“固定的”＃39;在下一个mpl版本中。

如果拥有mac的任何人（每个人？）都知道如何向Apple报告错误，那么这将是一件好事。

brian2没有在anaconda python发行版中导入
