python3 运行出现'ascii' codec can't encode characters in position 10-11: ordinal not in range(128)错误解决方案

‘ascii’ codec can’t encode characters in position 10-11: ordinal not in range(128)

最近，部署测试环境时新启用了一台Ubuntu，安装完python3执行写好的脚本时报错，差了下基本属于编码问题

可尝试如下解决：

A subtle problem causing even print to fail is having your environment variables set wrong, eg. here LC_ALL set to "C". In Debian they discourage setting it: Debian wiki on Locale

vim /etc/default/locale
#File generated by update-locale
#LANG="en_US"
LANG="en_US.UTF-8"
LANGUAGE="en_US:"

$ echo $LANG
en_US.utf8
$ echo $LC_ALL 
C
$ python -c "print (u'voil\u00e0')"
Traceback (most recent call last):
  File "", line 1, in 
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe0' in position 4: ordinal not in range(128)
$ export LC_ALL='en_US.utf8'
$ python -c "print (u'voil\u00e0')"
voilà
$ unset LC_ALL
$ python -c "print (u'voil\u00e0')"
voilà

import sys
reload(sys)
sys.setdefaultencoding('utf-8')
