Gridsome build failing with TypeError

Question

I'm encountering some trouble running Gridsome build on a starter project template. The site runs on localhost with no problem. I tried npm install gridsome@latest to update or install any missing packages.

Gridsome build gives me the following error:

    Could not generate HTML for "/work/":
    TypeError: Cannot read property 'console' of null
      at Object. (C:\Users\Micah\Desktop\my-gridsome-site\node_modules\vue-meta\dist\vue-meta.common.js:103:23)

      at Object. (webpack:/external "vue-meta":1:0)

The code at vue-meta.common.js:103:23 reads var console = _global.console || {}; var console = _global.console || {}; as shown below:

var hasGlobalWindow = hasGlobalWindowFn();

var _global = hasGlobalWindow ? window : global;

var console = _global.console || {};
function warn(str) {
  /* istanbul ignore next */
  if (!console || !console.warn) {
    return;
  }

  console.warn(str);
}
var showWarningNotSupported = function showWarningNotSupported() {
  return warn('This vue app/component has no vue-meta configuration');
};

Steps to reproduce

Run gridsome build from command line.

I think the problem is only in build because of lack of SSR (server side rendering) of your component. There is no window in build mode. Try to wrap your component inside vue's <template> tag with <ClientOnly> tag like this:

<template>
  <ClientOnly>
    <my-component />
  </ClientOnly>
</template>
