Django的同治命令导致错误

Question

我有以下的cronjob：

0 0 * * * source /home/admin/data/virtualenvs/myapp/bin/activate && python /home/admin/data/virtualenvs/myapp/project/manage.py 1c-import >> /home/admin/data/logs/1c-import.log 2>&1 

所以，在日志文件中我看到以下错误：

Traceback (most recent call last): 
    File "/home/admin/data/virtualenvs/myapp/project/manage.py", line 28, in <module> 
    execute_from_command_line(sys.argv) 
    File "/home/admin/data/virtualenvs/myapp/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 443, in execute_from_command_line 
    utility.execute()

    File "/home/admin/data/virtualenvs/myapp/local/lib/python2.7/site-packages/django/core/management/base.py", line 232, in execute

    File "/home/admin/data/virtualenvs/myapp/project/helper/management/commands/1c-import.py", line 94, in handle 
    print 'Product [%s] with price %s and qty %s' % (product_title, product_price, product_qty) 
UnicodeEncodeError: 'ascii' codec can't encode characters in position 34-35: ordinal not in range(128) 

但是当我尝试手动运行THIC命令 - 没关系。你怎么看 - 有什么可能导致这个错误？

Answer 1

我的猜测是，当从cron作业运行它时，系统会尝试将产品标题，价格和数量转换为ASCII，而您在手动运行时选择不同的编码。 您的一个或多个产品将拥有标题，价格和/或数量中的字符，这些字符不能编码为ASCII。

它是否帮助，如果你打印的信息是这样？：

ENCODING = "utf-8" 
print 'Product [%s] with price %s and qty %s' % (product_title.encode(ENCODING), 
         product_price.encode(ENCODING), product_qty.encode(ENCODING)) 

Answer 2

的问题将是该locale的cron设置不正确。

在/etc/environment设置

LANG=en_US.UTF-8

而且这个问题也：Python3: UnicodeEncodeError only when run from crontab
