Doesn't work with Ganache 7.0

[cgewecke]

Some ganache internals have been made private... plugin crashes with:

> UnhandledRejections detected
Promise {
  <rejected> TypeError: Cannot read private member from an object whose class did not declare it
      at __classPrivateFieldGet (/home/circleci/project/metacoin/node_modules/ganache/dist/node/webpack:/Ganache/core/lib/src/server.js:10:94)

Would need to begin using the new provider event api:

[davidmurdoch]

Let me know if you want help updating to the new event system.

@davidmurdoch @cgewecke How did this issue of "Cannot read private member from an object whose class did not declare it" is resolved. Could you please help me in that. I'm exactly on the same issue.

[leiiiooo]

solidity

you get solution or not??

[arithmetric]

Have you tried the beta version described here?

I was encountering the error TypeError: Cannot read private member from an object whose class did not declare it and it was fixed by upgrading to solidity-coverage version 0.8.0-beta.1.

[davidmurdoch]

@cgewecke Just checking in on this again. Do you need an help from the Truffle team?

[cgewecke]

@davidmurdoch Apologies, i'll have time to take a look this week.

[johnnyshankman]

Have you tried the beta version #700 (comment)?

I was encountering the error TypeError: Cannot read private member from an object whose class did not declare it and > it was fixed by upgrading to solidity-coverage version 0.8.0-beta.1.

This just results in it using a backup legacy version of ganache-cli which is deprecated.

⚠️  There was a problem attaching to the ganache VM.
⚠️  For help, see the "client" & "providerOptions" syntax in solidity-coverage docs.
⚠️  Using ganache-cli (v2.13.2) instead.

@arithmetric

I have this issue currently as well. My two options are pin ganache to an older version or as the above states, use the beta which fallsback to deprecated ganache-cli 2.13.2.

[mfigurski80]

Hey all! It seems like version 0.8.0-beta.1 doesn't support truffle, but there's a 0.8.x-truffle branch present in the repo -- is there any chance that is published and I can install that to fix?

Alternatively, how do I go about downgrading ganache? Which version has been working?

[davidmurdoch]

@cgewecke, anything I can do to help?

[johnnyshankman]

Ran into this today using ganache at ^7.0.0

[magiconch]

Same bug, I use ganache ^7.3.2 and "solidity-coverage": "^0.7.21".

[davidmurdoch]

@cgewecke, we'd love to help here! Can you point us in the right direction to get the work done?

[monperrus]

FTR, tried today with Ganache 7.4.3, same issue.

[davidmurdoch]

@cgewecke, we'd still love to help here! Can you point us in the right direction to get the work done?

Did it work with any option?

[cgewecke]

RIP ganache.

Sad day.
