Eclipse Oxygen 4.7.0 中的 PyDev 5.9.2 运行时错误答案

【问题描述】：

我在 Windows 7 和 WinPython 3.6.0.1 上使用作为 Eclipse 扩展（通过更新站点）安装的 PyDev。即使语法检查器损坏，我也可以很好地运行代码，即标记为错误“未定义变量：打印”行就像

print("hello")

我认为这个问题与我在启动 Eclipse 后立即进入错误日志的错误有关：

Error creating python process - exited before creating sockets - exitValue = (1).

这是异常堆栈跟踪

java.lang.RuntimeException: Error creating python process - exited before creating sockets - exitValue = (1).

所以，显然错误是这样的

ModuleNotFoundError: No module named '_pydevd_bundle'

我尝试重新安装 PyDev（看起来安装可能已损坏），但无济于事。想法？

【解决方案1】：

我可能真的发现了这个问题。我发现我安装的 WinPython 发行版是“WinPython Zero”，它没有附带额外的软件包。我卸载了它并安装了“默认”WinPython；现在调试器按预期工作。我想那时需要一些库来启用调试。也许在这里提供更多信息的错误消息会有所帮助，因为我得到的这个确实没有说太多。

有趣的是，这正是 PyCharm 中发生的事情：https://youtrack.jetbrains.com/issue/PY-24198
