当我在Google云应用引擎上使用Markojs部署应用程序Nodejs和Markojs时，出现错误“ EROFS：只读文件系统…”。

Question

I'm new in Google Cloud Resources.

I'm deploying a Nodejs(with Markojs) application at google cloud's app engine and I'm getting the error "EROFS: read-only file system, open '/srv/src/app/converter/form/.7.1565968890124.converter.marko.js'"

At Google documentaion is said "Filesystem The runtime includes a full filesystem. The filesystem is read-only except for the location /tmp, which is a virtual disk storing data in your App Engine instance's RAM."

Link: https://cloud.google.com/appengine/docs/standard/nodejs/runtime#filesystem

I ran "echo $PATH" from "Production environment" and I got "/srv/node_modules/.bin/:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

I'm trying set up the environment variable "PATH" in order to fix the path "/srv/.node_modules to /tmp/.node_modules". I don't know whether it'll fix the problem.

On app.yaml file I wrote,

# [START runtime]
runtime: nodejs10

env_variables:
  ## Put production environment variables here.
  ## PATH: /tmp/node_modules/.bin/:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
  PATH: /tmp/node_modules/.bin/:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
  _: /tmp
  HOME: /tmp

The full error is:

Error: EROFS: read-only file system, open '/srv/src/app/converter/form/.7.1565968890124.converter.marko.js' at Object.openSync (fs.js:443:3) at Object.writeFileSync (fs.js:1194:35) at compile (/srv/node_modules/marko/dist/node-require/index.js:61:16) at Object.markoRequireExtension [as .marko] (/srv/node_modules/marko/dist/node-require/index.js:115:27) at Module.load (internal/modules/cjs/loader.js:653:32) at tryModuleLoad (internal/modules/cjs/loader.js:593:12) at Function.Module._load (internal/modules/cjs/loader.js:585:3) at Module.require (internal/modules/cjs/loader.js:690:17) at require (internal/modules/cjs/helpers.js:25:18)

Thank you very much in advance!

The marko/node-require hook writes to the filesystem by default, but you can configure this:

require("marko/node-require").install({
  writeToDisk: false
});
