在使用fish shell时，导入pandas时出现错误'unknown locale: UTF-8' (Mac OS X)。

Question

我最近升级到了Python 3.5和最新版本的pandas pandas (0.17.1)，但这让我的程序出现了问题。我使用的是Mac OS X 10.9.5操作系统，并且使用fish shell。请问我该怎么办？

我不使用bash，而是fish——这个解决方案如何适用？ - clstaudt

尝试按照http://conda.pydata.org/docs/troubleshooting.html#unknown-locale的建议去做。 - hi15

Answer 1

适用于Fish Shell

set -x LC_ALL en_US.UTF-8 
set -x LANG en_US.UTF-8

是的，将这些行添加到~/.config/fish/config.fish可以解决问题。 - clstaudt

你不希望设置 LC_ALL - 那是一个旨在调试或覆盖的巨锤，不应轻易使用。 - faho

只有当您说英语并居住在美国时，这才是正确的答案，而对于看到此问题的人来说，这几乎从未发生过。一般情况下，您应该将其设置为适合您所在地区的正确代码（locale -a 将列出所有可用选项）。 - asmeurer

Answer 2

确保您的终端设置为导出适当的区域变量，如this answer所述，并且在系统偏好设置中正确设置了您的地区。

看起来两者已经设置正确，所以我无法确认这是否已解决了我的问题。 - clstaudt
