Blitz: [Linux] getting "Object.fromEntries is not a function" when retrieving dependencies

[pcrunn]

What is the problem?

I can't create a new project because the blitz cli can't retrieve the dependencies

Steps to Reproduce:

1. Clear npm module cache (if it exists and blitz's project dependencies are in there)
2. Create a new project using
   blitz new myapp

Versions:

debug: global
debug: pkgPath: /usr/local/lib/node_modules/blitz/node_modules/@blitzjs/cli/lib/src/index.js

Linux 4.19 | linux-x64 | Node: v10.20.1

blitz: 0.8.0 (global)

Supporting Documentation

Here is the exact error i'm getting

(this is after the project's file structure is created)

Thanks for reporting this issue @pcrunn 👍 we will look into this asap.

Btw, I just checked this out and I'm also have a problem with generating.

Couldn't find any versions for "eslint-plugin-react-hooks" that matches "39"

@pcrunn this should be fixed in 0.8.1 — can you test and verify?

It seems the error occurs here:
https://github.com/blitz-js/blitz/blob/canary/packages/generator/src/utils/fetch-latest-version-for.ts#L29

Object.fromEntries() is supported from Node.js ver. 12.x .

// test.js
const entries = new Map([
  ['foo', 'bar'],
  ['baz', 42]
]);

const obj = Object.fromEntries(entries);

console.log(obj);
// expected output: Object { foo: "bar", baz: 42 }

@is2ei that's what I thought, but the @pcrunn said he has Node: v10.20.1, which doesn't make sense. 🤔

[flybayer]

We can either refactor this or add a polyfill or something

@flybayer

he has Node: v10.20.1

That is why he found the error. If he uses 12.x , he won't get the error.

I agree with you.
