brian2 未在 anaconda python 发行版中导入

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()

    return rc_params_from_file(fname, fail_on_error)
  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？与matplotlib和pylab有关吗？

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 的错误，因为他们没有将本地环境变量设置为标准值：

正如@msw 在评论中所说，解决方法是

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 是一项建议的修复。这应该是下一个 mpl 版本中的 'fixed'。

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