python - 处理 4 - 线程 "AWT-EventQueue-0"中的异常

Question

我尝试在 Ubuntu 20 上使用 processing-4.0b6-linux-x64。

它与 Java 和 p5.js 配合良好。不幸的是，它根本不适用于 Python。

当我通过 ./processing 从终端运行应用程序时，命令行中会出现某种警告:

does not exist created registry at port 8220 could not create registry; assume it's already created

无论如何，GUI 运行良好，但运行的代码非常简单:

def setup():
    size(800, 600)
    
def draw():
    pass

不起作用，我收到以下错误列表:

我有java

openjdk 11.0.13 2021-10-19
OpenJDK Runtime Environment (build 11.0.13+8-Ubuntu-0ubuntu1.20.04)
OpenJDK 64-Bit Server VM (build 11.0.13+8-Ubuntu-0ubuntu1.20.04, mixed mode, sharing)

和javac

javac 11.0.13

已经安装。有什么建议吗？

这只是 beta 6 版本中的一个回归:删除了 Python 模式仍在使用的方法。

已报道here并针对 beta 7 进行了修复(当可用时)，或者如果您从源代码构建。
