EOFError: marshal data too short

Answer 1

我还遇到了错误：

EOFError:元帅数据太短了。

即使没有对任何现有文件进行更改，也会引发此错误。

一些*.pyc文件是自动创建的，这些文件是脚本的编译字节码，在运行Python以加快以后的启动时会动态创建这些字节码。

我正在使用Oracle管理器，用于Python。

我试图安装pyspark。星火文件夹结构如下所示

spark****/python/pyspark 

在此文件夹下包含一个名为“__pycache__”的文件夹，我使用命令删除了“__pycache__”文件夹：

rm -r __pycache__/

这消除了我的错误，我现在可以进口火花放电。

希望这能有所帮助。

Answer 2

我使用终端删除所有.pyc文件，它对我起作用。

find . -name \*.pyc -delete
