【中文标题】在python 2.7中导入熊猫时出现“ValueError：未知语言环境：UTF-8” [重复]

【英文标题】："ValueError: unknown locale: UTF-8" when importing pandas in python 2.7 [duplicate]

【问题描述】：

我是 python 新手，想学习使用 pandas，但我什至无法在我的 python 中正确使用包。

在我尝试过的终端中

$ conda install pandas

结果是：

Fetching package metadata .......
Solving package specifications: ..........

# All requested packages already installed.
# packages in environment at /Users/rudyyuan/anaconda:
#
pandas                    0.18.1              np111py27_0  
Rudy-Yuans-MBP:~ rudyyuan$ 

然后我尝试使用 pip 安装：

Rudy-Yuans-MBP:~ rudyyuan$ pip install pandas
Requirement already satisfied (use --upgrade to upgrade): pandas in        
./anaconda/lib/python2.7/site-packages
Requirement already satisfied (use --upgrade to upgrade): python-dateutil in     
./anaconda/lib/python2.7/site-packages (from pandas)
Requirement already satisfied (use --upgrade to upgrade): pytz>=2011k in    
./anaconda/lib/python2.7/site-packages (from pandas)
Requirement already satisfied (use --upgrade to upgrade): numpy>=1.7.0 in 
./anaconda/lib/python2.7/site-packages (from pandas)
Requirement already satisfied (use --upgrade to upgrade): six>=1.5 in
./anaconda/lib/python2.7/site-packages (from python-dateutil->pandas)

然后我进入

$ python

然后我进入

$ import pandas

输入命令的结果：

    raise ValueError, 'unknown locale: %s' % localename
ValueError: unknown locale: UTF-8

但是当我尝试使用这个在本地检查包时：

import pip
sorted(["%s==%s" % (i.key, i.version) for i in pip.get_installed_distributions()])

里面已经显示了熊猫……：

什么问题以及如何解决这个问题？有什么和路径有关的吗？

我对 python 很陌生。

有什么问题？ 我们如何修复它？

【问题讨论】：

可能与IPython Notebook locale error和Pelican 3.3 pelican-quickstart error “ValueError: unknown locale: UTF-8”有关

【参考方案1】：

看起来您使用的是 OS X。将此附加到您的 ~/.bash_profile：

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

然后运行：

$ source ~/.bash_profile

现在试试import pandas。

【讨论】：

天哪，它就像魔术一样工作！！！非常感谢你！

@HernandoAndriantoWillyRen 如果有效，请务必将答案标记为已接受:)

每次打开python之前我导入东西都必须使用它吗？

没有@HernandoAndriantoWillyRen。它会一直在你的 ~/.bash_profile 中。

还修复了下载spaCy语言模型的错误：D
