python - 在pycharm中调试python代码

Question

这个问题类似于this一。我正在尝试调试 pyethapp使用以下配置:

入口点位于 app.py 中。代码在未调试时运行良好，但一旦我启动调试器，就会抛出以下异常:

Failed to import scrypt. This is not a fatal error but does
mean that you cannot create or decrypt privkey jsons that use
scrypt

/usr/local/lib/python2.7/dist-packages/cffi/model.py:526: UserWarning: 'point_conversion_form_t' has no values explicitly defined; next version will refuse to guess which integer type it is meant to be (unsigned/signed, int/long)
  % self._get_c_name())
Traceback (most recent call last):
  File "/home/user/Utils/pycharm-community-2016.1/helpers/pydev/pydevd.py", line 1530, in <module>
    globals = debugger.run(setup['file'], None, None, is_module)
  File "/home/user/Utils/pycharm-community-2016.1/helpers/pydev/pydevd.py", line 937, in run
    pydev_imports.execfile(file, globals, locals)  # execute the script

    return original_import(name, *args, **kwargs)
  File "console_service.py", line 38, in <module>
    @inputhook_manager.register('gevent')
AttributeError: 'InputHookManager' object has no attribute 'register'

建议的解决方案here (重新安装ipython)没有解决问题(只在调试时出现；客户端单独运行时有效)。

编辑:

输出中的命令行:

已知如果您使用旧版本的 IPython(其中确实尚未实现 register 方法)，就会发生此错误。由于您可能使用 OSX，其中包含默认的 Python 安装，因此您的环境中可能存在一些冲突的 Ipython 副本，常规和调试配置调用了不同版本的 Ipython 副本？

这个问题可能通过将项目移动到您的根包无法干扰的虚拟环境来解决。
