pip install-locale.Error：不支持的语言环境设置

Question

完整的堆栈跟踪：

➜  ~ pip install virtualenv
Traceback (most recent call last):
  File "/usr/bin/pip", line 11, in <module>
    sys.exit(main())
  File "/usr/lib/python3.4/site-packages/pip/__init__.py", line 215, in main
    locale.setlocale(locale.LC_ALL, '')
  File "/usr/lib64/python3.4/locale.py", line 592, in setlocale
    return _setlocale(category, locale)
locale.Error: unsupported locale setting

在同一台服务器上，我成功运行pip install virtualenv了python2.7.x。

现在，我刚刚使用安装了python3.4 curl https://bootstrap.pypa.io/get-pip.py | python3.4。

➜  ~ pip --version
pip 8.1.1 from /usr/lib/python3.4/site-packages (python 3.4)

pip uninstall virtualenv 也会引发相同的错误

Answer 1

根本原因是：您的环境变量LC_ALL丢失或无效

简短答案-

只需运行以下命令：

$ export LC_ALL=C

如果在新的终端窗口中仍然出现错误，请在.bashrc文件底部添加错误。

长答案-

这是我的locale设置：

$ locale
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_COLLATE="C"
LC_MONETARY="C"
LC_MESSAGES="C"
LC_PAPER="C"
LC_NAME="C"
LC_ADDRESS="C"
LC_TELEPHONE="C"
LC_MEASUREMENT="C"
LC_IDENTIFICATION="C"
LC_ALL=C

Python2.7

    $ uname -a
