挂载后linux / dev / shm创建lxml.etree.SerialisationError

Question

为了解决错误[OSError]：设备上没有剩余空间，我已经卸载并重新安装/ dev / shm。我以为这可能会释放内存，但是令我惊讶的是，尽管它释放了内存，但它阻止了我的文件运行。我无法通过命令提示符运行任何python文件，甚至无法保存任何文件。它说“设备上没有剩余空间”。另外，如果我运行程序，则无论文件如何，它始终会给我以下错误。在卸载之前，所有这些文件都在运行。

重新安装后会丢失任何数据吗？如果是这样，有什么选择可以让我重新执行重新安装的操作。我已经在根目录中运行了以下命令：

umount /dev/shm
mount -o remount /dv/shm

我想环境文件可能存在问题，必须运行该环境文件来设置配置。这就是为什么会出现此错误的原因。但是我无法追踪到底缺少了什么，需要修复什么。我也尝试增加/ dev / shm的内存。它显示了新增加的内存，但仍然给我错误，说如果我执行任何操作都没有空间。我无法弄清楚这个“序列化错误”。
