Question

我刚刚安装了python 2.7.13和Django 1.11.4。我创建了一个名为myproject的项目，并尝试从下面的命令开始，但它会抛出UnicodeDecodeError错误。

python manage.py runserver

UnicodeDecodeError: 'ascii' codec can't decode byte 0xf1 in position 6: ordinal not in range(128)

我没有配置任何其他内容，只是尝试启动开发服务器但它失败了。

Answer 1

此错误表示

UnicodeDecodeError: 'ascii' codec can't decode byte 0xf1 in position 6: ordinal not in range(128)

表名中有非ascii字符。 0xf1通常是带有波浪号的拉丁小写字母n的扩展ASCII码。

严格的ASCII只有最多128个字符（0x80）。智能程序员意识到他们在分配给一个字符的1字节内存中有另外128个可能的值，因此他们创建了EXTENDED ASCII。但是每个人都有不同的想法，那就是导致CODEPAGES描述你的EXTENDED ASCII方案的原因。这一切都被UNICODE所取代，UNICODE允许所有真实和想象语言中的每个可能的字符都有自己独特的字节值。如何编码是各种规格的主题，例如UFT-8，UTF-16＆amp; ISO-8859-1。

解决方案：从表名中删除违规字符，生活很美好。

UnicodeDecodeError序号不在范围内（128）
