Python-ValueError:未知区域设置：UTF-8

我运行了包含Pandas（导致问题的那个）库的python脚本。我遇到了以下错误：

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

我还在终端首选项中启用了启动时设置语言环境变量

---

恐怕这个问题是由El Capitan引起的。

编辑：熊猫及其依赖项在非C语言环境中发现，并在最新版本中修复

当我通过sudo pip install Pandas将Pandas的最新版本下载到一台OS X Yosemite计算机上，并将其安装在一个终端集上，然后在一个新的Python会话中导入时，我无法重现这个问题

我现在最好的猜测——我要强调这只是一个猜测——是该文件夹中的熊猫版本早于这些修复，并在它的u it.UTF-8中被破坏。（总的来说，我确实认为这比卡皮坦特有的问题更有可能发生。）

您的LC_ALL=未设置。这似乎不寻常；基于此，我认为您应该尝试将其设置为LC_ALL=“it_it.UTF-8”，并删除其他LC_设置

---

然后保存您的.bash_配置文件，打开新的终端选项卡，然后重试。

这与您的终端编码无关，它只会影响终端中文本流的显示。我需要修复此问题。这会影响我的结果。我不认为这是一个重复的问题，因为set LC_ALL对我不起作用。对我来说，解决方案是在终端的首选项启动时取消选中Set locale env variables。。。您可能是指代码块中的

LC\u ALL=“it\u it.UTF-8”

。哎呀！现在修好了，谢谢

LC\U ALL

通常不在OSX上设置，但

LANG

是。如果其他人（通常）也设置了

LC\u ALL

，您只需将

LC\u ALL

设置为覆盖。你的

LC\u ALL=…

命令有效地覆盖了你的

LANG=…

命令-两者都不需要。为了支持@mklement0的声明：

man-locale

。浏览了

man-locale

，我理解我在这里错了。这不会改变OP的原始区域设置。
