Lesson 6 : FileNotFoundError

[wilonweb]

Hello
When I launch the command brownie run scripts/deploy.py --network ganache-local
I find a FileNotFoundError: [Errno 2] No such file or directory: 'ganache'
the output is :

wilfried@DESKTOP-FQ2D16J:~/smartContract/brownie_fund_me$ brownie run scripts/deploy.py --network ganache-local

ganache local corresponds to a ganache UI instance, doesn't it?
So As I've commented on the other thread, please go to your ganache setting and change the server to WSL

[wilonweb]

Hello
i put the server to WSL

But i got always the FileNotFoundError0

[cromewar]

remember when you change the ser rpc server to wsl, the http address is going to be different, so please add the network again with the new http address.

[wilonweb]

I have already add the network ganache-local
With this command ganache-local host=http://127.0.0.1:7545 cmd=ganache and the host enter is the same than i cas see on ganache UI

Do you know the command to find information like the host about a network ?

O it's true, I'm not comfortable yet ...
So i remake the network :

SUCCESS: A new network 'ganache-local' has been added

    ├─cmd: ganache
    ├─cmd_settings: {}

But when i launch the script and i get always the same problem.

preferably you should close the ganache cli before opening the ui one, they uses the same ports and could get on conflict

[wilonweb]

I opened Ganache UI before Visual Studio Code.
And i did not get the WSL server in the hostname section.

After i opened Visual Studio Code with the project on WSL, and after that i can get the vEthernet(WSL) host name on the UI.
So i select it, and i get always the same problem when l aunch the command

[cromewar]

You should have running the WSL server before opening ganache...
Still this error si really strange, have you any thoughts on this @PatrickAlphaC ?

[wilonweb]

Juste before i had to delete the folder ganache present on %APPDATA.
Now i closed VSC and i opened Ganache UI and i can acces to WSL hostname.
After i opened VSC to launch brownie run scripts/deploy.py --network ganache-local Brownie v1.18.1 - Python development framework for Ethereum but i have always the error

[sako013]

try networkid=1337 ,it more like a bug of ganache

[sako013]

and restart the ganache

[wilonweb]

VSC was already open.
I opened ganache UI and on server section and i get only 0.0.0.0 - All Interfaces hostname
I launch ganache-cli on the terminal WSL
all the hostname are appeared
So i change th id 5777 to 1337
I launch the command brownie run scripts/deploy.py --network ganache-local
And i get always the same error

sorry for the delay, I'll answer you today.

[wilonweb]

I appreciate it, that's very kind of you, I'll be free from Thursday, it's not in a hurry.

[wilonweb]

Thanks a lot for your help

[PatrickAlphaC]

Could you make this a stack exchange ETH question? It might be something odd going on.

[cromewar]

@PatrickAlphaC The problem is already solved but we had to go into a on-to-one call to solve it ;)

[cromewar]

Problem solved just adding and selecting the correct network.
