Syntax Error upon import

[guyroyse]

I'm getting a syntax error doing the simplest of things:

$ npm install --save redisai-js

I copy and paste the Vanilla JS tensor example from the README.md into a file named redisai-js.js. And then I run it:

$ node redisai-js.js

And it gives me this error:

/Users/guyroyse/code/redis-modules-assessment/node_modules/redisai-js/lib/tensor.js:49
    });
    ^

SyntaxError: Unexpected token '}'

    at Object.Module._extensions..js (internal/modules/cjs/loader.js:1035:10)

I pulled the repo down myself, built everything, and npm installed the folder on my machine and it worked. Seems like something wrong with our npm depoly? Maybe?

Hi there @guyroyse , I've created a empty project and used the sample tensor from the readme and it seems to work for me. Do we differ in any of the following versions?:

filipe@filipe-ThinkPad-T490:/tmp/test$ node --version
v14.13.0
filipe@filipe-ThinkPad-T490:/tmp/test$ npm list 
test@1.0.0 /tmp/test
└─┬ redisai-js@1.0.0
  ├─┬ @types/redis@2.8.28
  │ └── @types/node@14.14.25
  └─┬ redis@3.0.2
    ├── denque@1.5.0
    ├── redis-commands@1.6.0
    ├── redis-errors@1.2.0
    └─┬ redis-parser@3.0.0
      └── redis-errors@1.2.0 deduped

filipe@filipe-ThinkPad-T490:/tmp/test$ node tensor.js 
AI.TENSORSET result: OK
AI.TENSORGET reply: datatype FLOAT shape [1,2] , data [3,5]

PS: nonetheless, to be sure, I can add the Readme examples to the CI as part of clean independent examples ( each of them ). wdyt?

That certainly couldn't hurt. I checked my version and stuff to compare and upgraded my Node from 12 to 14. But, still getting the error. This is really weird:

14:55:01 guyroyse@macaquebook.local ~/code/redisai-syntax-error 
🐵 node server.js 
/Users/guyroyse/code/redisai-syntax-error/node_modules/redisai-js/lib/tensor.js:49
    });
    ^

How did you install Node? I'm using nvm.

Note: Yes. I have a monkey in my command prompt. ;)

I am able to reproduce @guyroyse findings using Mac OS Catalina 10.15.7 and Node 14.16.0, here's my output:

$ node server.js
/Users/simonprickett/source/github/redisai-syntax-error/node_modules/redisai-js/lib/tensor.js:49
    });
    ^

I am running macOS Catalina 10.15.7 as well. I also experienced this same problem on an earlier Mac.
