Question

我正在pydev网站上进行“入门”，一切都按照描述进行，直到我进入http://www.pydev.org/manual_101_run.html上有关调试的部分。但是，我现在收到警告“找不到使用cython的调试器加速”，然后在尝试处理该异常时出现错误。

我要运行的代码名为example.py：

'''
Created on Nov 7, 2018

@author: Chris
'''
if __name__ == '__main__':
    print('Hello World')

当我在不打开调试模式的情况下运行此命令时，它将在控制台上正确打印“ Hello World”。按照入门页面中的建议，我在第7行添加了一个断点，并在调试模式下（通过按F11键）重新运行了代码。这样做时，我得到以下控制台输出：

warning: Debugger speedups using cython not found. Run '"C:\Users\Chris\AppData\Local\Programs\Python\Python37\python.exe" "C:\Users\Chris\.p2\pool\plugins\org.python.pydev.core_7.0.0.201811071319\pysrc\setup_cython.py" build_ext --inplace' to build.

During handling of the above exception, another exception occurred:

相关问题Eclipse pydev warning - "Debugger speedups using cython not found."建议在警告的第一行中运行代码

"C:\Users\Chris\AppData\Local\Programs\Python\Python37\python.exe" "C:\Users\Chris\.p2\pool\plugins\org.python.pydev.core_7.0.0.201811071319\pysrc\setup_cython.py" build_ext --inplace

这样做时，出现以下错误

  File "<input>", line 1

如果情况不太明显，我是python，eclipse，StackOverflow和PyDev的最高新手-今天上午在每个人中都开始这样做。

首先要解决的问题是，https://stackoverflow.com/a/53210935/110451（在您的情况下，只需将PyDev升级到7.0.3即可解决此问题）。

关于无法重新生成cython加速器模块，现在应执行：

"C:\Users\Chris\AppData\Local\Programs\Python\Python37\python.exe" "C:\Users\Chris\.p2\pool\plugins\org.python.pydev.core_7.0.0.201811071319\pysrc\setup_cython.py" build_ext --inplace

在您的终端中（即：在cmd.exe中），而不是作为Python模块...
