一、安装xlrd和xlwt功能模块步骤
1.使用python -V查看python的版本号,并查看python安装环境,是否安装成功;
2.可以通过官网(python官网:https://pypi.python.org/pypi)或者其他手段获取到功能模块的安装程序包;
3.将程序包解压,并放在python->Lib文件下
4.在cmd命令窗口中,进入E:PythonPython36Lib目录下,分别进入xlrd和xlwt的目录下,执行python setup.py install命令;
5.在python工具中,执行import xlwt3和import xlrd,运行结果没有报错,则证明安装成功;
二、在使用xlwt时,报错的解决方法
1.导入xlwt3报错:ValueError: cannot use LOCALE flag with a str pattern
详细错误信息:
Traceback (most recent call last):
File "F:/1/1", line 1, in <module>
import xlwt3
File "E:PythonPython36libsite-packagesxlwt3\__init__.py", line 3, in <module>

from .worksheet import Worksheet

File "E:PythonPython36lib

return _compile(pattern, flags)
File "E:PythonPython36lib

p = sre_compile.compile(pattern, flags)
File "E:PythonPython36libsre_compile.py", line 562, in compile
p = sre_parse.parse(p, flags)
File "E:PythonPython36libsre_parse.py", line 866, in parse
p.pattern.flags = fix_flags(str, p.pattern.flags)
File "E:PythonPython36libsre_parse.py", line 833, in fix_flags
raise ValueError("cannot use LOCALE flag with a str pattern")
ValueError: cannot use LOCALE flag with a str pattern
解决方法:
进入E:PythonPython36Libsre_parse.py文件下,修改该代码:
if flags & SRE_FLAG_LOCALE:
pass #stone20170712 raise ValueError("cannot use LOCALE flag with a str pattern")
pass #stone20170712 raise ValueError("cannot use LOCALE flag with a str pattern")
执行import xlwt3,结果OK
2.导入xlwt3报错:ValueError: '__init__' in __slots__ conflicts with class variable
详细错误信息:
Traceback (most recent call last):
File "F:/1/1", line 1, in <module>
import xlwt3
File "E:PythonPython36libsite-packagesxlwt3\__init__.py", line 3, in <module>
from .workbook import Workbook
File "E:PythonPython36libsite-packagesxlwt3workbook.py", line 5, in <module>
from .worksheet import Worksheet
File "E:PythonPython36libsite-packagesxlwt3worksheet.py", line 7, in <module>
from .row import Row
File "E:PythonPython36libsite-packagesxlwt3
ow.py", line 8, in <module>
from . import formula
File "E:PythonPython36libsite-packagesxlwt3formula.py", line 6, in <module>
class Formula(object):
ValueError: '__init__' in __slots__ conflicts with class variable
解决方法:
进入E:PythonPython36Libsite-packagesxlwt3formula.py文件下,将其中
__slots__ = [ "__init__","__s", "__parser", "__sheet_refs", "__xcall_refs"]
修改为:
__slots__ = [ "__s", "__parser", "__sheet_refs", "__xcall_refs"]
执行import xlwt3,结果OK
