javascript - 谷歌云功能部署 : EROFS: read-only file system

Question

我正在尝试将我的 api 部署到 Google Cloud Functions，我得到了这个:

EROFS: read-only file system, mkdir '/user_code/uploads'

⚠  functions[post]: Deployment error. Function load error: 
    Code in file index.js can't be loaded. Is there a syntax error in your code?

Cloud Functions 运行时中的所有内容都是只读的，除了 os.tmpdir() (这很可能是 /tmp，但您不应该这样假设)。如果您有任何代码(例如，在 api/user.js 中)试图在其他任何地方编写，它将出错。
