Hi @beloved
You seem to be in the system 32 folder, change directory and navigate into the root directory of your project and run npm install -g [email protected]
Cheers,

Having the same problem here @filip. @Kim_model did you find a solution? The trick @Nile mentioned did not work for me. Even restarting ganache and power shell and deploying a-fresh did not work. It even got worse and the getMessage function previously recognized will now also throw this error:
truffle(ganache)> instance.getMessage()
evalmachine.:0
instance.getMessage()
^
Uncaught TypeError: instance.getMessage is not a function

truffle(ganache)>
EDIT: also this shows up when only calling the instance to see all functions of the contract
truffle(ganache)> instance2
[Function: bound deployed] AsyncFunction
UPDATE:
I could make it run somehow, I am not sure though why it works out now. After defining the 4th Instance of the contract it worked out suddenly.
Made me remember why I took a break from Coding and Computers many years ago, lol
UPDATE 2:
For anyone struggling with this:
Try to create a new instance after you deploy/migrate again, this does the trick for me. Anyhow, truffle migrate --reset does only work for me, if I also create a new instance. another way is to exit the truffle console with .exit and restarting it, as this will clear all instances. Then, to make sure, migrate again with migrate --reset, set your new instance with let instance = await contractname.deployed()
Hope this helps
@filip in the ErrorHandling video you say that the migration will catch an error because we do not meet the require statement, because we are not sending in 1 ETH but a million wei. I am a little confused because I can migrate --reset it without an error and console.log(âSuccessâ) will call.
Why is that? What did I miss?
how pls can u email me the procedure
Hi @Bhujanga
If you are able to deploy it means that the require statement pass successfully, it would revert otherwise 
Please post both your migration file and your contract.

Dani
Hey @beloved
I searched on YouTube for you and I found a really easy video that explains how to use cd.
Check it out: https://www.youtube.com/watch?v=BfXh11ryBJg

@dan-i Thank you for your reply. I found out what was different in my contract to Filipâs. I just missed that he inserted a require statement in the function. So it would throw no error with my contract, as there was no require function.

I am rewatching the truffle Setter Function video. How would I input a value for the deposit function?
I tried instance.deposit({value: 1000000000000000000}) but it wonât update the balance. The transaction goes through, but is not updating the balanceâŚ
Hey @dan-i !
You are my Hero of the day !

I had so many problems with this course and decided to take a break and complete the new version of Smart Contract 1.0. Iâm done with that now. So now I started this course over again. Iâm following Filipâs instructions step-by-step through the video and cannot get pass the setter video course.
I inserted the setMessage function into the Helloworld.sol file as Filip instructed. Then, I entered:
let instance = await Helloworld.deployed()
But the screen states that instance has already been declared.
Very frustrated with this course!
If we have to use metamask to do this course, Iâm quitting. I used metamask once before this course and my experience with it was awful. I tried to buy some altcoins and found that the transaction fee was nearly $300. I didnât want to pay that of course, so I tried to pull my money out of metamask, but there was a display error that showed that all my funds had disappeared! I was very stressed about that of course, and stayed up late into the night to try to fix it. I eventually got my money back by uninstalling and reinstalling metamask. The rest of my week was awful because metamask had caused me to lose sleep on the weekend and I wasnât able to catch up on sleep until the next weekend. I was so tired that I was clumsy one morning and smashed my face into a table in the dark and broke a tooth. I know metamask isnât directly responsible for making me lose my tooth, but it still left a strong impression on me. I will never use metamask again.
Hey @MrSeven
This is a javascript error.
In all programming languages, you cannot declare the same variable twice, however you can assign a new value to a variable already declared
You cannot do:
let instance = 10;
let instance = 20;
You can do:
let instance = 10;
instance = 20;
The compiler is telling you that instance has already been declared, therefore you have to assign a new value to it.
Happy learning,
Dani
