有一天在 PyCharm 中搞弄 Python 的时候，遇到了一个很傻的问题。也就是说，当我尝试在名为 的文件中运行一个简单的脚本时abc.py，我收到一个错误。我尝试直接从终端运行相同的文件，看起来不错。

abc.py

print("Hello world")

输出：

/Users/.../venv/bin/python /Users/.../abc.py
Fatal Python error: init_sys_streams: can't initialize sys standard streams
Traceback (most recent call last):
  File "/usr/local/Cellar/python/3.7.7/Frameworks/Python.framework/Versions/3.7/lib/python3.7/io.py", line 52, in <module>
  File "/Users/.../abc.py", line 1, in <module>
RuntimeError: lost sys.stdout

Process finished with exit code 134 (interrupted by signal 6: SIGABRT)

只是出于好奇，这里有什么问题？

编辑：为什么它只在从 PyCharm 运行时发生，而不是从终端运行时发生？

我有带有 Spring Batch 框架的 Spring Boot 应用程序。我的目标很简单——同时运行某些工作。比方说，我希望能够同时运行 15 个线程并拒绝每个多余的线程。这是我的配置类：

        return jobRegistryBeanPostProcessor;
    }
