Lesson6: Error while $ forge create........

[yasharyan0904]

This is the code

hp@lap:~/solidity/foundry-xxx$ forge create SimpleStorage --rpc-url http://127.0.0.1:8545 --private-k
ey 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80

This is the output

[⠒] Compiling...
No files changed, compilation skipped
Error: 
error sending request for url (http://127.0.0.1:8545/): error trying to connect: tcp connect error: Connection refused (os error 111)

Context:
- Error #0: error trying to connect: tcp connect error: Connection refused (os error 111)
- Error #1: tcp connect error: Connection refused (os error 111)
- Error #2: Connection refused (os error 111)

Can anyone tell me why this error is popping??
NOTE: anvil is working, it's showing all the wallets and the private keys.

Have you tried connecting to Ganache?

Do you get "Listening on 127.0.0.1:8545" at the bottom after running anvil in the command line?

[yasharyan0904]

Yes

Hello @yasharyan0904, Please use the below command and let us know how it plays out.

forge create src/SimpleStorage.sol:SimpleStorage --private-key 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80 --rpc-url http://127.0.0.1:8545

if your SimpleStorage contract path is not the same as mine (src/SimpleStorage.sol:SimpleStorage) please use the appropriate path to where your SimpleStorage contract is located.

[yasharyan0904]

Tried, it's giving the same error :(

[EngrPips]

I am convinced you are not running an anvil chain on another terminal.

[yasharyan0904]

By writing the following code:

forge create src/SimpleStorage.sol:SimpleStorage --private-key 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80 --rpc-url http://127.0.0.1:8545 --force 

The error:

The compilation is successful but it is not able to deploy the contract :(

[EngrPips]

I re-created your error by killing my terminal just to prove that you are not running an anvil chain on a second terminal.

[EngrPips]

You need to run a second terminal where you will run the anvil command to spin up an anvil blockchain, and you leave it running, then you can run this command forge create src/SimpleStorage.sol:SimpleStorage --private-key 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80 --rpc-url http://127.0.0.1:8545 and everything should work just fine.

[yasharyan0904]

EUREKA, it worked . Thanks a lot :)

[EngrPips]
