调试pycharm中的python代码

Question

这个问题与此类似.我正在尝试 使用以下配置调试pyethapp:

入口点位于app.py中.没有被调试时代码运行正常,但是一旦我启动调试器,就抛出以下异常:

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
  File "app.py", line 27, in <module>
    from console_service import Console
  File "/home/user/Utils/pycharm-community-2016.1/helpers/pydev/_pydev_bundle/pydev_monkey_qt.py", line 71, in patched_import
    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'

这里建议的解决方案(重新安装ipython)没有解决问题(它仅在调试时发生;客户端在单独运行时工作).

编辑:

输出中的命令行:

如果您使用旧版本的 IPython（实际上该方法register尚未实现），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，常规配置和调试配置会调用不同版本的 Ipython 副本？

通过将项目移动到根包无法干扰的虚拟环境，可能可以解决此问题。
