Lesson 9: Error while deploying to Rinkeby

[SpeedBird789]

Hi guys,

When I deploy at 16:22:41, I'm getting this following error:
[Error: ENOENT: no such file or directory, open '/home/speedbird789/hh-fcc2/hardhat-smartcontract-lottery/artifacts/build-info/10e66f6437a2c54fa041cba289ce5285.json']
{ errno: -2, code: 'ENOENT', syscall: 'open', path: '/home/speedbird789/hh-fcc2/hardhat-smartcontract-lottery/artifacts/build-info/10e66f6437a2c54fa041cba289ce5285.json' }

Could someone kindly have a look at what's the issue here? GitHub repo:

I'm afraid it doesn't really help

@SpeedBird789 : Follow the steps:

1. Do yarn hardhat clean then,
2. Delete you node_modules folder, then
3. Go to terminal and run : yarn, To install them again.

Try this and let me know, If it works!

[SpeedBird789]

Ahh great, it works! Thanks a lot

@abossofmyself sorry to bother you again but I'm having another error and this probably is the last one of this lesson hopefully. The error is at 16:31:01 when running yarn hardhat test
It ran successfully last night when you helped me to get those 14 tests running. But now this:

@SpeedBird789 : And do not run this on rinkeby , if you are testing unit tests only!

Just run : yarn hardhat test will be just fine, but follow the above steps first.

[SpeedBird789]

@SpeedBird789 : Don't worry :

First run : yarn hardhat deploy then , Run : yarn hardhat test

when I run yarn hardhat deploy I get another error:

@SpeedBird789 : Correct the name of the mock contract in your deploy script and change that,

From this : vrfCoordinatorV2Mock

To this : VRFCoordinatorV2Mock

ahhh silly me. You're a genuine lifesaver mate. Lesson 9 done and dusted!

You should indent everything properly. You can use Prettier to do this.

Also, there is a pending PR from @abossofmyself; assuming from the thread that he already reviewed the logic of the code, I made PRs for just the hardhat and helper config.
