调试pycharm中的python代码

Question

这个问题与this类似。我正在尝试调试pyethapp 使用以下配置：

入口点位于 app.py 中。未调试时代码运行正常，但是一旦启动调试器，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
  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'

解决方案建议here（重新安装ipython）没有解决问题（仅在调试时发生;客户端在单独运行时工作）。

Answer 1

如果您使用旧版本的IPython（其中方法register尚未实现），则会发生此错误。由于您可能使用OSX，其中包含默认的Python安装，您的环境中可能存在一些冲突的Ipython副本，其常规和调试配置会调用其不同版本？

通过将项目移动到根软件包无法干扰的虚拟环境中，可能会解决此问题。

要摆脱cython missing警告，请运行：

python2  /.......git/liclipse/plugins/org.python.pydev_6.2.0.201711281546/pysrc/setu p_cython.py  build_ext --inplace

最后，调试窗口保持清除那些可怕的警告和混乱。
