模块在windows下安装正常，在linux下安装出错
-
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe8 in position 0: ordinal not in range(128)
不知道怎么回事，有不少东东在windows下OK,但在linux下就是不行，不知道是否有人碰到过同样的问题。

把具体的问题和log弄上来看看。
这个UnicodeDecodeError的产生是由于要将byte string就是普通的字符串转化为Unicode字符串时，因为原字符串中有[b]非[/b]Ascii码的字符比如中文，而解码时又没有提供该字符串的编码，导致Python使用默认的Ascii来解码，从而出错。
这样的问题确实不少，只能具体问题具体分析了。

看来这个地方的源代码，没有搞明白，help me.

从log看是在安装模块到创建字段时出了‘UnicodeDecodeError'。所以大概你的实体类中的字段定义中用了非Ascii码的字符，是中文吗? 是不是应该用unicode字符串的地方比如：u'中文', 用成了byte string: '中文'。如果在unicode字符串中用了中文字符，还要注意在源文件的起始位置定义encoding。
如果在windows下可以安装，linux下出错，看看这里是不是出错的原因： www.shine-it.net/viewthread.php?tid=581&extra=page%3D2

安装报表不成，搞的原来都是好的模块都不能保持，救命，郁闷。

原因未明，重新安装server就可以了。
