我的 Django 项目叫做 mysite
这是我执行的命令：

执行上述命令后build，dist和mysite.spec被创造，但dist不包含mysite.exe

File "C:\Python\lib\encodings\cp1252.py", line 23, in decode
return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x8f in position 311: char

以下是我用来读取文件的代码
with open(log_file, 'r') as log_file_fh:
for line in log_file_fh:
print(line)
我试图通过使用不同的编码模式来修复它，如 ascii、utf8、utf-8、ISO-8859-1、cp1252、cp850。但仍然面临同样的问题。有什么办法可以解决这个问题。
