Doesn't work if install all modules, but works if I install only
#nestjs/platform-socket.io: "9.1.6" and #nestjs/websockets: "9.1.6".
What am I doing wrong?
/node_modules/#nestjs/platform-socket.io/node_modules/engine.io/build/server.js:474
const listeners = server.listeners("request").slice(0);

TypeError: Cannot read properties of undefined (reading 'slice')

Test2 is main function reference to test3.
Both functions are in different files.
It produce error.C_and_CPP/test2.c:12: undefined reference to `test3'
So basically I am just getting started with Truffle and I have created my first Solidity code, which looks like this:
pragma solidity ^0.4.4;
contract HelloWorld
{
function SayHello() internal pure returns (string)
{
return ("Hello World!");
}
}
I then opened Powershell and ran the following command: testrpc Than I compiled and migrated my code using "truffle" compile and "truffle migrate"
The problems started occurring when I opened "truffle console" and did this, giving me an error at the end:
PS C:\Users**\MetaCoin> truffle console
truffle(development)> var hw
undefined
truffle(development)> HelloWorld.deployed().then(function(deployed){hw=deployed});
undefined
truffle(development)> hw.SayHello.call()
TypeError: Cannot read property 'call' of undefined
truffle(development)>
Can someone help me with this? Thanks.
I have an Arduino with an Ethernet shield.
I have the httpclient library, and I am trying to run the PachubeClient example.
When I compile, it gives me many errors:
PachubeClient.cpp:25:25: error: Credentials.h: No such file or directory
PachubeClient.cpp: In function 'void setup()':
PachubeClient:47: error: 'ssid' was not declared in this scope
PachubeClient:47: error: 'passphrase' was not declared in this scope
PachubeClient:55: error: a function-definition is not allowed here before '{' token
PachubeClient:95: error: expected `}' at end of input
Why?
I haven't played around with the Arduino development environment at all but that error message means you're either missing the Credentials.h file or the compiler doesn't know where to find it. Verify that the file exists and then check your compiler settings to make sure that you're passing it the path to the header files.
