--snapshot-blob=path

与 --build-snapshot 一起使用时，--snapshot-blob 指定写入生成的快照 blob 的路径。如果不指定，生成的 blob 会写入当前工作目录下的 snapshot.blob。

¥When used with --build-snapshot, --snapshot-blob specifies the path where the generated snapshot blob is written to. If not specified, the generated blob is written to snapshot.blob in the current working directory.

在没有 --build-snapshot 的情况下使用时，--snapshot-blob 指定用于恢复应用状态的 blob 的路径。

¥When used without --build-snapshot, --snapshot-blob specifies the path to the blob that is used to restore the application state.

加载快照时，Node.js 检查：

¥When loading a snapshot, Node.js checks that:

1. 正在运行的 Node.js 二进制文件的版本、体系结构和平台与生成快照的二进制文件完全相同。

   ¥The version, architecture, and platform of the running Node.js binary are exactly the same as that of the binary that generates the snapshot.

2. V8 标志和 CPU 功能与生成快照的二进制文件兼容。

   ¥The V8 flags and CPU features are compatible with that of the binary that generates the snapshot.

如果它们不匹配，Node.js 拒绝加载快照并以状态码 1 退出。

¥If they don't match, Node.js refuses to load the snapshot and exits with status code 1.
