Module version mismatch. Expected 48, got 47.

I’m working on a project that often runs hot and cold. As it happens, I haven’t run a build in a little over a month (it’s been a cold period). At the time, it worked just fine. Today, though, I tried to run a build and got this:

Module version mismatch. Expected 48, got 47.

In my project root, I have the following package.json:

{
  "name": "status-meter",
  "productName": "Status Meter",
  "description": "Status Meter is like a fuel gauge for your data allowance.",
  "homepage": "http://services.myclient.com/statusmeter",
  "repository": {
    "type": "git",
    "url": "https://bitbucket.org/owner/repo"
  },
  "dependencies": {
    "aws-sdk": "^2.2.15",
    "electron-builder": "^2.11.0",
    "electron-packager": "^6.0.2",
    "electron-prebuilt": "^0.36.0"
  },
  "scripts": {
    "clean": "rm -rf dist",
    "clean:osx": "rm -rf dist/osx",
    "clean:win": "rm -rf dist/win",
    "build": "npm run clean && npm run build:osx && npm run build:win",
    "build:osx": "npm run clean:osx && electron-packager ./app \"Status Meter\" --ignore=node_modules/.bin --out=dist/osx/ --platform=darwin --arch=x64 --version=0.36.12 --icon=\"build/assets/osx/Status Meter.icns\" --prune --app-bundle-id=\"com.myclient.statusmeter\" --app-version=$(node -e 'console.log(require(\"./app/package.json\").version)')",
    "build:win": "npm run clean:win && electron-packager ./app \"Status Meter\" --ignore=node_modules/.bin --out=dist/win/ --platform=win32 --arch=ia32 --version=0.36.12 --icon=\"build/assets/win/Status Meter.ico\" --prune --app-version=$(node -e 'console.log(require(\"./app/package.json\").version)')",
    "pack": "npm run pack:osx && npm run pack:win",
    "pack:osx": "npm run build:osx && electron-builder \"dist/osx/Status Meter-darwin-x64/Status Meter.app\" --platform=osx --out=dist/osx/ --config=build/config.json",
    "pack:win": "npm run build:win && electron-builder \"dist/win/Status Meter-win32-ia32\" --platform=win --out=dist/win/ --config=build/config.json",
    "nightly": "npm run pack && node bin/upload.js"
  }
}

I run the build by simply executing

$ npm run nightly

Locally, I’m running Node v6.0.0.

My issue seems similar to #39, but I’m not certain of that. I’ve been looking around for a map of electron version to the packaged node version, but haven’t found one yet. Any advice would be a big help.

1. Remove node_modules directory completely (rm -rf node_modules).
2. Please ensure that you don’t use sudo.
3. npm install.

Would you mind taking a minute to explain what you clearly knew

Well, npm is not reliable and buggy. So, it is like a windows — if something goes wrong, first step is to reboot machine (i.e. remove cache and old node_modules) 😃
