gevent+redispy:SystemError:NULL结果在PyObject_C中没有错误

Question

我和gevent一起使用redispy和redish，我有自己的类EventBot，它继承了Greenlet。在

在这个类的__init__方法中，我使用

self._redis = Client(serializer=serialization.JSON(), **self.REDIS_CONFIG)

有时当我试图运行脚本时，它抛出SystemError: NULL result without error in PyObject_Call，但有时它正常启动。我还尝试将redis初始化移动到_run()方法，但没有起到任何作用。在

这是我使用的简化类：

^{pr2}$

以下是完整的回溯：

任何帮助都将不胜感激。在

编辑：

当使用gevent和greenlet系统包时，问题似乎得到了解决（在ArchLinux中，python2-gevent和{}），但根据它们的PKGBUILD，没有进行额外的修补。（gevent，greenlet）有人能解释一下使用pip安装的错误吗？在

根据这个主题的the GitHub issue，您还可以使用CFLAGS="-O2 -fno-tree-dominator-opts"来获得常规的编译器优化，但是没有segfaults。在
