pycharm调试器中的python3.4 AssertionError

I have Pycharm 3.1 installed (latest version) which supposedly supports python 3.4, however, this morning it started throwing exceptions whenever I run debugger. Is there anything I can do to fix this AssertionError?

我已经安装了Pycharm 3.1(最新版本)，据说它支持python 3.4，然而，今天早上我运行调试器时，它就开始抛出异常。我能做些什么来修复这个AssertionError?

Process finished with exit code -1

-- Edit --

I ended up deleting the .py file and recreating the code in a new file, after that, debugger works correctly. I am not sure what corrupts these files, but I have noticed it has happened on several different occasions. AssertionError was one of those times. Another time a .py file got corrupted and the interpreter was throwing an exception that I haven't defined a coding style for unicode char support, even though I had

最后，我删除了.py文件并在一个新文件中重新创建代码，之后，调试器工作正常。我不知道是什么腐蚀了这些文件，但我注意到它已经发生在不同的场合。AssertionError是其中之一。另一次，.py文件损坏，解释器抛出了一个异常，我没有为unicode char支持定义编码样式，尽管我有

# -*- coding: utf-8 -*-

What surprised me, even after deleting the whole code (including # -- coding: utf-8 --) and basically calling a simple print() func it would still continue throwing the error! Then again I ended up completely deleting the file and starting from scratch. I felt really shocked, I have no idea how this happened.

令我惊讶的是，即使删除了整个代码(包括#——编码:utf-8——)并调用了一个简单的print() func，它仍然会继续抛出错误!然后，我再次完全删除文件并从头开始。我真的很震惊，我不知道这是怎么发生的。

2 个解决方案

#1

I meet this problem by using PyCharm 3.1.1 and Python 3.4.0 in Windows.

我在Windows中使用PyCharm 3.1.1和Python 3.4.0来解决这个问题。

This is a bug(http://youtrack.jetbrains.com/issue/PY-12317), which is marked "Fixed in 3.1.2".

这是一个bug(http://youtrack.jetbrains.com/issue/PY-12317)，它被标记为“3.1.2中修复”。

Thus, I download PyCharm 3.1.2RC2(build 133.1143) in JetBrains PyCharm Preview (EAP) page. And, that version solved this problem.

因此，我下载了PyCharm 3.2 rc2 (build 133.1143)在JetBrains PyCharm预览(EAP)页面上。这个版本解决了这个问题。
