1 问题

今天在测试服务器上执行 pip list 发现

(conf) root@xxxxx:xxxxx# pip list
Traceback (most recent call last):
  File "/srv/www/vinyl.ddapp.com/conf/bin/pip",line 11,in <module>
    sys.exit(main())
  File "/srv/www/vinyl.ddapp.com/conf/lib/python3.6/site-packages/pip/__init__.py",line 215,in main
    locale.setlocale(locale.LC_ALL,'')
  File "/usr/lib/python3.6/locale.py",line 598,in setlocale
    return _setlocale(category,locale)
locale.Error: unsupported locale setting

这就很尴尬了，看下本机的 locale

locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE=zh_CN.UTF-8
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

发现 LC_ALL 为空

2 解决方法

2.1 重置环境变量

export LC_ALL="en_US.UTF-8"

2.2 重新刷入配置

运行命令 dpkg-reconfigure locales

在次查看 locale

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

最后运行 pip list 就正常了
