You can use npm or yarn both are package managers and you can have both installed, i do use both of them (some packages use yarn, some npm).

I am getting this error message. Though the file is there, power shell is stating it isn’t there. Please advise
Try the new cross-platform PowerShell https://aka.ms/pscore6

I followed the path for yarn. When I try to install it does not let me or recognize the file. I went into windows and set it to enable scripting.
the file will not install. What do you suggest?
Thank you, Rachel

Hey @Rachel3, hope you are ok.

What is exactly the issue? you have installed yarn properly (apparently no errors).

Some times powershell might run into issues with some programs. I advice you to use the windows console (CMD) that one will give you less issues.

basically you should learn how to move into folders in CLI (command line interface), cd is the command keyword you use to go into a folder… the first error in your post is that your path finish with a file, so cd is not intended to open the file, just the folder, so any time you need to go into a folder, just finish the path with the folder name like your example :nerd_face:

Hi!
Please help me.
I can not mark “Installing NodeJS & Atom” lecture complete. It just doesn not happen. I tried several times, but it just cannot let me move on. In other courses it works.

#439

Hey @balintdaniel13, i assume you refers to the Academy 2.0, please try again, we have done some fixes on those lesson related to the same issue.

If still persist, let us know to solve it asap.

Hi!
I am trying to do the buy order from the lesson, but my order gets automatically cancelled, below the code and response:
const GeminiAPI = require(“gemini-api”).default;

const secret = “2BhC7gzpYGMQTn3MtKaDUEqg47SN”;
const key = “account-dPQJYSZHgcy06XlZnjkc”;
const restClient = new GeminiAPI({key, secret, sandbox:true});

restClient.newOrder({amount:10, price:100, side:“buy”, symbol:“btcusd”})
.then(response => console.log(response));

Hey guys,

I’m using MacOS. Node.js and the npm are working fine when using it in the terminal/command line. But when trying to install Yarn I’m getting an error message.

Can’t manage to solve it. Appreciate any help.

Thanks!!!

hey @Robert12, hope you are ok.

You might have to run the commands with admin privilege try to add sudo at the start of entire command (Example: sudo npm install), sudo is the keyword to use admin privileges on the terminal.

Hi @thecil,
I refer to Ivan’s video “Building MA strategy”. At the end when programming the 2nd if-statement (Sell condition).
Did he forget to amend the function “exchange.marketBuyBitcoin” into "“exchange.marketSellBitcoin”?

Best regards,

Indeed, nice catch, it should change it to SellBitcoin, but might be that he just forgot on that moment. :nerd_face:

Hi guys

I thought I followed everything that Ivan did, but I must be missing something. Can someone take a look and see if you can see what I’m missing?

Here is my code:

const GeminiAPI = require(“gemini-api”).default;
const secret = “5rWhrEsP2hBjFKLjU7qTJxYSAEw”;
const key = “bAynhBcbELVwPDBrRL5o”;
const restClient = new GeminiAPI({key, secret, sandbox:true});
restClient.newOrder({amount:10,price:100,side:“buy”,symbol:“btcusd”})
.then(response => console.log(response));

And here is my error:

PS E:\BUSINESS\Bitcoin\IvanOnTechAcademy\Bot> node index.js
node:internal/process/promises:246
triggerUncaughtException(err, true /* fromPromise */);
^

[UnhandledPromiseRejection: This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason “#”.] {
code: ←[32m’ERR_UNHANDLED_REJECTION’←[39m

Thanks in advance for your assistance.
