由于Python无法处理太短的编组数据，因此请提供更多的编组数据：)。 - Willem Van Onsem

但是现在认真地说：您需要提供更多的上下文。哪一部分代码正在执行这个操作？ - Willem Van Onsem

似乎与损坏的.pyc文件有关。 - sshashank124

我也遇到了同样的错误。在@sshashank124的评论的帮助下，我通过删除不仅是主程序目录下的__pycache__，还包括导入的包的__pycache__来解决了这个问题。你可以通过像这样的find命令找到__pycache__：$ find /usr/local/lib/python3.5/dist-packages/ -name __pycache__ | grep django/utils或类似的方式。 - shuuji3

在我的情况下，通过scp发送的py文件刚好损坏了，重新做一遍就解决了。 - j riv

我使用终端删除了所有的.pyc文件，这对我起到了作用。

find . -name \*.pyc -delete

我也遇到了这个错误:

EOFError: marshal数据太短.

即使没有对任何现有文件进行更改，也会抛出此错误。

一些*.pyc文件会自动创建，它们是脚本的编译字节码，当Python脚本运行以加速未来的启动时，会动态创建该脚本。

我正在使用Oracle VM VirtualBox管理器，在Python上工作。

我试图安装pyspark。Spark文件夹结构如下:

spark****/python/pyspark

在这个文件夹下包含一个名为'__pycache__'的文件夹。我进入了pyspark文件夹并使用以下命令删除了'__pycache__'文件夹：

在终端输入如下命令：

rm -r pyspark/__pycache__

rm -r __pycache__/

这个方法解决了我的错误，现在我能够导入pyspark。

希望这可以帮到你。
