Issue

npm install truffle-contract --save-dev fails with the following error:

But the following steps work:

1. npm install [email protected] --save-dev
   
   
   
   • this would produce the same error as above
   
   
2. After 1, npm install truffle-contract --save-dev works fine.
   
   
   
   • [email protected] is installed correctly
   
   

Steps to Reproduce

1. npm install truffle-contract --save-dev => error
2. npm install [email protected] --save-dev => error
3. npm install truffle-contract --save-dev => success

Expected Behavior

Step 1 should work fine

Environment

• Operating System: Windows 10
• Truffle version (v5.0.29):
• node version (v10.15.3):
• npm version (6.4.1):

Will have to look into this. Thanks for raising the issue!

Hi, is this still a problem on the most recent version of Truffle Contract? Thank you!

[sebastiantf]

I'm not sure. I haven't been using truffle for some time now.

Closing for issue maintenance. If you want us to pursue this further then please do get back to us and we'll try to help you out! Thanks!

Yes it's still an issue. I have yet to find a work around.

Ah, yeah this still would be an issue when installing @truffle/contract as a devDep. https://github.com/trufflesuite/truffle/blob/develop/packages/contract/package.json#L44

See the PlantUML diagram in https://github.com/trufflesuite/truffle/issues/3175.

Hi @PatrickAlphaC thanks for getting back to us! Can you try this again with the latest version of @truffle/contract? If that doesn't work, can you provide reproduction steps (if they are different in any way from those in the original issue)? Thanks!

[CruzMolina]

Scratch what I said earlier. @truffle/contract isn't pulling down ganache-core when installed as a devDep.

Looks like this was an old issue with web3 having node-gyp as a deeply nested dependency in beta.37.
This issue should be resolved on latest truffle-contract and @truffle/contract.

[PatrickAlphaC]

Works for me now :)

Very cool, closing this.
