Nodejs-storage: ReferenceError: Invalid left-hand side in assignment when importing @google-cloud/storage in nodejs

[TRDRakesh]

I am getting error when I import @google-cloud/storage in nodejs,

const gcs = require('@google-cloud/storage');

I have tried importing using:

1. const {Storage} = require('@google-cloud/storage');
   const storage = new Storage();
2. let gcs = require('@google-cloud/storage');
   But I get the same error.
   When I comment the line, everything works fine. Below is the error I get:

Environment details

• OS: Ubuntu 19.04
• Node.js version: 10.15.2
• npm version: 6.9.0
• @google-cloud/storage version:

Steps to reproduce

1. package.json contains: "@google-cloud/storage": "^1.7.0",

Making sure to follow these steps will guarantee the quickest resolution possible.

Thanks!

[AVaksman]

@TRDRakesh for the

const {Storage} = require('@google-cloud/storage');
const storage = new Storage();

syntax to work please update to the latest "@google-cloud/storage" version: "^2.5.0".

---

In "@google-cloud/storage" version: "^1.7.0" the correct import syntax would be

const Storage = require('@google-cloud/storage');

[TRDRakesh]

@AVaksman It's not working, I tried adding ^2.5.0 already and in 1.7.0 I was using the correct syntax

[AVaksman]

@TRDRakesh
Please see below the code snippets that I tried testing with
For
@google-cloud/storage version: ^2.5.0
Node.js version: 10.15.2

packaje.json dependencies section

  "dependencies": {
    "@google-cloud/storage": "^2.5.0",
    "uuid": "^3.3.2"
  }

// Imports the Google Cloud client library
const {Storage} = require('@google-cloud/storage');
const uuid = require('uuid/v4');

// Creates a client
const storage = new Storage();

const bucketName = `bucket-name-${uuid().split('-').shift()}`;
const bucket = storage.bucket(bucketName);

async function createBucket() {
  // Creates the new bucket
  await storage.createBucket(bucketName);
  console.log(`Bucket ${bucketName} created.`);
  await bucket.delete();
  console.log('deleted');
}

createBucket();



md5-a993e929a406ed9921445b2af4ada3b8



```ts
// Imports the Google Cloud client library
const Storage = require('@google-cloud/storage');
const uuid = require('uuid/v4');

// Creates a client
const storage = new Storage();

const bucketName = `bucket-name-${uuid().split('-').shift()}`;
const bucket = storage.bucket(bucketName);

async function createBucket() {
  // Creates the new bucket
  await storage.createBucket(bucketName);
  console.log(`Bucket ${bucketName} created.`);
  await bucket.delete();
  console.log('deleted');
}

createBucket();

These worked for me.

Please tell me what I should change to reproduce the issue you are experiencing.

[JustinBeckwith]

To add to this... what version of node.js are you using?

[AVaksman]

To add to this... what version of node.js are you using?

Edited my previous post, using Node.js 10.15.2 for the code snippets.

[TRDRakesh]

@AVaksman doesn't work, gives the same issue

[bcoe]

@TRDRakesh :wave: would you mind providing the following:

node --version
npm --version

[TRDRakesh]

@bcoe It's already mentioned, Node.js version: 10.15.2
npm version: 6.9.0

[bcoe]

@TRDRakesh I apologize, missed the version in your original PR.

Could you please provide a gist with a minimum reproduction of the issue you're seeing?

[bcoe]

@TRDRakesh mind also providing an example of the code that pulls in the nodejs-storage dependency? I have a hunch as to what the issue might be, but would like to see your usage in context.

[TRDRakesh]

@bcoe I didn't understood which code you want,
I have tried importing using:
const {Storage} = require('@google-cloud/storage');
const storage = new Storage();

let gcs = require('@google-cloud/storage');
But I get the same error.

[bcoe]

@TRDRakesh would you be able to provide the contents of server.js?

[TRDRakesh]

I have many things in server.js file, but I have tried using just one line, i.e:
const gcs = require('@google-cloud/storage');
gives the same error

[bcoe]

@TRDRakesh in a new folder on your computer, e.g., /tmp/test, do the following:

bencoe@bencoe:/tmp/test$ node --version
v10.15.3
bencoe@bencoe:/tmp/test$ npm i @google-cloud/storage
npm WARN [email protected] No description
npm WARN [email protected] No repository field.

updated 1 package and audited 728 packages in 0.982s

bencoe@bencoe:/tmp/test$ node
> const gcs = require('@google-cloud/storage');
undefined

Does this run without any error?

[TRDRakesh]

My output:

$ node --version

$ sudo npm i @google-cloud/storage

[bcoe]

@TRDRakesh this suggests that when you install @google-cloud/storage in a fresh project, you do not receive the error:

SyntaxError: Unexpected token *

I'm guessing that somewhere in your server.js code there might be invalid syntax. Keep in mind that, unless you have a TypeScript compiler, or are using a module like esm, the syntax import * will not work, and will raise the exception you're seeing.

If you remove references to import * from your repo, I think things might work for you.

[TRDRakesh]

I get this error:

I will see the syntax and correct it, I didn't use import * anywhere.
Thanks a lot!

[JustinBeckwith]

Wait a second.....

$ sudo npm i @google-cloud/storage

If you're installing like that, it's very likely you're getting something different when you actually import your code. Let's do this:

In general, you really want to avoid globally installing modules like that, unless you're using them as command line tools.

Can you try this?

$ cd ~/
$ npm unlink @google-cloud/storage
$ cd <your-code-directory>
$ npm install
$ npm ls @google-cloud/storage

[cstrd]

@JustinBeckwith Thanks a ton! It worked!!

[cstrd]

@JustinBeckwith The issue is coming again Please help!

[cstrd]

@bcoe Sir can you please look into the issue again

[JustinBeckwith]

If you're having the same error you were having before, the steps we laid out above are probably the same fix.

[cstrd]

@JustinBeckwith I tried it, It doesn't solve the issue.
