Wxpython脚本给出“TypeError:”in<string>“需要字符串作为左操作数，而不是QString”

Question

这个简单的wxpytohn脚本给出了以下错误，怎么了？错误消息不会给出脚本中发生错误的行：

Traceback (most recent call last):
  File "c:\Python27\lib\site-packages\spyderlib\plugins\externalconsole.py", line 721, in run_script_in_current_shell
    "and try again.") % osp.basename(filename), QMessageBox.Ok)
  File "c:\Python27\lib\ntpath.py", line 198, in basename
    return split(p)[1]
  File "c:\Python27\lib\ntpath.py", line 173, in split
    while i and p[i-1] not in '/\\':
TypeError: 'in <string>' requires string as left operand, not QString

脚本如下：

^{pr2}$

Answer 1

问题似乎是

p[i-1] not in '/\\'

p[i-1]是QString，而Python需要一个字符串。也许是

^{pr2}$

解决问题。在

Answer 2

截至2015年12月，奇怪的是，同样的问题仍然存在，尽管据报道的1540问题已被修复：代码包含（例如）以下行：

newPath = os.path.dirname(newFile)

在蜘蛛下面跑。在windows中用cmd编译时，会抛出TypeError： TypeError:“in”需要字符串作为左操作数，而不是QString

您可以考虑：

^{pr2}$

Answer 3

此here存在spyderlib问题。显然它已经关闭了，所以也许可以尝试更新你的库，看看它是否仍然是个问题。在
