Migrating fails (Ganache and Truffle Develop)

[gideongrinberg]

• I've asked for help in the Truffle Gitter before filing this issue. (It was ~15 minutes ago, but I figured I'd fill out an issue anyway. I also asked on the Etherum Discord)

Issue

Truffle is unable to find contracts in a subdirectory when I'm using ganache.

Steps to Reproduce

First Attempt:

1. truffle init to create a new project
2. Write contracts into contracts/ and tests into tests/ (all contracts compiled and all tests passed.
3. Start Ganache, add a network in truffle-config.js
4. Run truffle migrate --network development

Second Attempt:

1. Steps 1 and 2 of the above
2. truffle develop and then migrate
3. This errors out as well.

Expected Behavior

The contracts would've compiled and migrated.

Actual Results

First Attempt:

Truffle couldn't find some of the files (all of which had worked for first time.) See this gist for the source and the error messages.

Second attempt:

New error. See this Gist.

Environment

• Operating System: macOS Catalina 10.15.7
• Ethereum client: Ganache
• Truffle version (truffle version): I've tried bot Truffle v4.1.14 and truffle@latest
• node version (node --version): v15.1.0
• npm version (npm --version): 7.0.8

There's a 99% chance I'm making a dumb mistake somewhere in these steps. Thanks in advance for any help!

(I'm also aware that these are two separate issues, but I'll leave them as one for now)

Possibly a duplicate of #2463, and related to #2070

[gideongrinberg]

Upgrading truffle caused yet another error, this time due to my solc version being wrong. I think I can fix that myself, so I'll close this.

[gideongrinberg]

With the newest version of Truffle, and solc@4.24.0, it still fails with the same error about not being able to find files.

@gideongrinberg you'll want to do artifacts.require("Rogue") rather than artifacts.require("Classes/Rogue"), since the string passed to that function is meant to be just the contract name, not a path.

Not sure why you're getting that uncaughtException error, but maybe try fixing your artifacts.require statement and seeing if that helps?

Thanks for reporting this!

[gideongrinberg]

Thanks for the reply @gnidan. It still doesn't work, same error:

truffle migrate --network development                                                                                                               [17:13:39]

Hi @gideongrinberg, is it possible to share your project with us? It will help us troubleshoot the entire workflow. Thanks!

Thanks for the response! I'm actually not sure if I still have the project, I'll see if I can find it.

Thanks @gideongrinberg! That would be super helpful! I can't duplicate your error from the steps you gave. I tried on Node 15 and it seemed to run just fine. I wonder what could be going on here...

I can't seem to find the project. I must've migrated it to hardhat before committing. It's very likely I made a dumb mistake somewhere. Thanks for all your help!
