python3中用HTMLTestRunner.py报ImportError: No module named 'StringIO'的解决方法:

1.原因是官网的是python2语法写的,看官手动把官网的HTMLTestRunner.py改成python3的语法:

参考:http://bbs.chinaunix.net/thread-4154743-1-1.html

下载地址:http://tungwaiyip.info/software/HTMLTestRunner.html

修改后下载地址:http://pan.baidu.com/s/1dEZQ0pz   (懒人直接下载吧)

2.修改汇总:

第94行,将import StringIO修改成import io

第539行,将self.outputBuffer = StringIO.StringIO()修改成self.outputBuffer = io.StringIO()

第642行,将if not rmap.has_key(cls):修改成if not cls in rmap:

第766行,将uo = o.decode('latin-1')修改成uo = e

第775行,将ue = e.decode('latin-1')修改成ue = e

第631行,将print >> sys.stderr, '\nTime Elapsed: %s' % (self.stopTime-self.startTime)修改成print(sys.stderr, '\nTime Elapsed: %s' % (self.stopTime-self.startTime))

在Python3.4下使用HTMLTestRunner,开始时,引入HTMLTestRunner模块报错。

在HTMLTestRunner的94行中,是使用的StringIO,但是Python3中,已经没有StringIO了。取而代之的是io.StringIO。所以将此行修改成import io

在HTMLTestRunner的539行中,self.outputBuffer = StringIO.StringIO()修改成self.outputBuffer = io.StringIO()

修改以后,成功引入模块了

执行脚本代码:

运行测试脚本后,发现报错:

File "C:\Python34\lib\HTMLTestRunner.py", line 642, in sortResult

if not rmap.has_key(cls):

所以前往642行修改代码:

运行后继续报错:

AttributeError: 'str' object has no attribute 'decode'

前往766, 772行继续修改(注意:766行是uo而772行是ue,当时眼瞎,没有注意到这些,以为是一样的,导致报了一些莫名其妙的错误,折腾的半天):

修改后运行,发现又报错:

File "C:\Python34\lib\HTMLTestRunner.py", line 631, in run

print >> sys.stderr, '\nTime Elapsed: %s' % (self.stopTime-self.startTime)

TypeError: unsupported operand type(s) for >>: 'builtin_function_or_method' and '_io.TextIOWrapper'

前往631查看,发现整个程序中,唯一一个print:

print >> sys.stderr, '\nTime Elapsed: %s' % (self.stopTime-self.startTime

这个是2.x的写法,咱们修改成3.x的print,修改如下:

print(sys.stderr, '\nTime Elapsed: %s' % (self.stopTime-self.startTime))
