You need to select
-> provableAPI_0.5.sol <-

And replace the name of the file in your contract

github.com

biahoi/coinFlip4/blob/coinFlip4_stage2_1/contracts/coinFlip100.sol

Yes. I did changed to provableAPI_0.5.sol; and change all “pragma …” definitions in all .sol files.
The same error:

truffle migrate --network ropsten --reset
Error parsing D:@TUNG 2020\IVANONTECH\SOLIDITY 201\coinFlip4\contracts\provableAPI_0.5.sol: ParsedContract.sol:32:137: ParserError: Expected ‘,’ but got identifier

Compilation failed. See above.

Hi @tungtien

I answered you question here
https://forumtest.ivanontech.com/t/programming-project-phase-2/10056/255

You are still not using the correct version or the provable API
oraclizeAPI_0.4.sol

tungtien · July 5, 2020, 4:29am

You are still not using the correct version or the provable API
oraclizeAPI_0.4.sol

That is the original provableAPI_0.5.sol file; I did not changed anything; The code you saw is this (I think that is just comment?) - but any way, I did not changed the content of this file:

*/
pragma solidity >= 0.5.0 < 0.6.0; // Incompatible compiler version - please select a compiler within the stated pragma range, or use a different version of the provableAPI!

// Dummy contract only used to emit to end-user they are using wrong solc
contract solcChecker {
/* INCOMPATIBLE SOLC: import the following instead: "github.com/oraclize/ethereum-api/oraclizeAPI_0.4.sol" */ function f(bytes calldata x) external;
}

Hello, anyone has problem with truffle crashing? It’s better with node v9 but it still crashes sometimes

Taha · August 18, 2020, 2:46pm

@Yogalholic
How frequently is it crashing?
If it really disturbs your development trying uninstalling and re-installing it.

Yogalholic · August 18, 2020, 7:33pm

Is it better to install node with msi or npm in vscode?

Taha · August 18, 2020, 10:24pm

@Yogalholic
I suggest to go for npm
npm has far more libraries.

Hello the command

Set-ItemProperty -Path HKLM:\Software\Policies\Microsoft\Windows\PowerShell -Name ExecutionPolicy -Value ByPass

Returns this error
Set-ItemProperty : Cannot find path 'HKLM:\Software\Policies\Microsoft\Windows\PowerShell' because it does not exist.

Thanks

@Yogalholic
Can you elaborate your question a bit more? I am not sure what are you trying to do here?

If this helps you sort your issue: https://social.technet.microsoft.com/Forums/en-US/3ef5e0d7-0a45-4e18-96df-3e6bad879004/setitemproperty-example-code-doesnt-work?forum=winserverpowershell

@gabba

Hello,

I’ve tried to follow the guide but at some point I got errors and so now I’m trying to do all over again.

In the first step after Set-ExecutionPolicy AllSigned I don’t get any error but anyway on Get-ExecutionPolicy -list i don’t get the machinepolicy allsigned:

 Scope ExecutionPolicy
        ----- ---------------
MachinePolicy       Undefined
   UserPolicy       Undefined
      Process       Undefined
  CurrentUser       AllSigned
 LocalMachine       AllSigned

if I try to do Set-ItemProperty -Path HKLM:\Software\Policies\Microsoft\Windows\PowerShell -Name ExecutionPolicy -Value ByPass

i get an error:

PS C:\WINDOWS\system32> Set-ItemProperty -Path HKLM:\Software\Policies\Microsoft\Windows\PowerShell -Name ExecutionPolicy -Value ByPass
Set-ItemProperty : Impossibile trovare il percorso 'HKLM:\Software\Policies\Microsoft\Windows\PowerShell' perché non
esiste.
In riga:1 car:1

   undException
    + FullyQualifiedErrorId : PathNotFound,Microsoft.PowerShell.Commands.SetItemPropertyCommand

I never used power shell before and I have no clue what to do (I didn’t get also how to change the language only in power shell).

How can I proceed? Thanks
