的Python - ValueError異常：未知區域：UTF-8

Question

我運行包含熊貓的python腳本（即一個導致問題）庫，我得到這個錯誤：

Traceback (most recent call last): 
    File "test.py", line 2, in <module> 
    import pandas 
ImportError: No module named pandas 

但是，如果我從包路徑中導入使確保它檢測到大熊貓庫，我得到這個錯誤信息

Traceback (most recent call last): 
    File "test.py", line 3, in <module> 
    import pandas

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

我已經更新我的.bash_profile和.bashrc與這些線，但仍無法正常工作，甚至我已經重新啓動終端和我的機器。

export LANG="it_IT.UTF-8" 
export LC_COLLATE="it_IT.UTF-8" 
export LC_CTYPE="it_IT.UTF-8" 
export LC_MESSAGES="it_IT.UTF-8" 
export LC_MONETARY="it_IT.UTF-8" 
export LC_NUMERIC="it_IT.UTF-8" 
export LC_TIME="it_IT.UTF-8" 
export LC_ALL="it_IT.UTF-8" 

我還在終端首選項中啓用了Set locale environment variables on startup。

恐怕造成的，因爲EI Capitan的問題。請指教。謝謝。

編輯：熊貓，和它的依賴，有localization bugs被發現在非C語言環境和最近版本。

當我通過sudo pip install pandas在設置爲it_IT.UTF-8的終端中將最新版本的Pandas下載到OS X Yosemite計算機上，然後將它導入到新的Python會話中時，我無法重現此問題。

我現在最好的猜測 - 我強調這只是一個猜測 - 是該文件夾中的熊貓版本早於這些修復，並在it_IT.UTF-8中被破解。 （我認爲這是，權衡利弊，較發行特定於埃爾卡皮坦更容易。）

你LC_ALL =未設置。這似乎不尋常;基於other answers here我認爲你應該嘗試將其設置爲LC_ALL =「it_IT.UTF-8」並刪除其他LC_設置。

然後保存您的.bash_profile，打開一個新的終端選項卡，然後重試。
