module.constants.compileCacheStatus

以下常量作为对象中返回的 status 字段返回，由 module.enableCompileCache() 用于指示尝试启用 模块编译缓存 的结果。

【The following constants are returned as the status field in the object returned by module.enableCompileCache() to indicate the result of the attempt to enable the module compile cache.】

Constant	Description
ENABLED	Node.js has enabled the compile cache successfully. The directory used to store the compile cache will be returned in the directory field in the returned object.
ALREADY_ENABLED	The compile cache has already been enabled before, either by a previous call to module.enableCompileCache(), or by the NODE_COMPILE_CACHE=dir environment variable. The directory used to store the compile cache will be returned in the directory field in the returned object.
FAILED	Node.js fails to enable the compile cache. This can be caused by the lack of permission to use the specified directory, or various kinds of file system errors. The detail of the failure will be returned in the message field in the returned object.
DISABLED	Node.js cannot enable the compile cache because the environment variable NODE_DISABLE_COMPILE_CACHE=1 has been set.
