python-2.7 - 只读文件系统 : '/dev/null' while running google-cloud-sdk project

Question

我正在尝试运行现有的 gcloud 项目。这个项目在我以前的笔记本电脑上运行良好。我将完全相同的 SDK 和项目复制到我的新笔记本电脑上，但不再工作了。
这是我面临的错误:

也在这里尝试了这个步骤steps但随后面临另一个错误，如 file not accessible /dev/null .任何帮助，将不胜感激。

Answer 1

由于您的初始错误是

IOError: [Errno 30] Read-only file system:

您可以尝试删除 logging.conf 一起或删除写入文件的处理程序(如果您的应用程序具有写入操作)，因为 App Engine 不支持对文件系统的任何写入操作(以及其他限制)。
