Cannot read property undefined in sol-compiler

[PaulRBerg]

Expected Behavior

Contracts should be compiled correctly when the compilerSettings are set in compiler.json.

Current Behavior

The following error is returned:

TypeError: Cannot read property 'Numbers' of undefined

Possible Solution

Well, if I remove the compilerSettings from compiler.json or the config file altogether, everything works fine. Perhaps tweaking the way the settings are interpreted would solve this issue.

Steps to Reproduce

1. git clone [email protected]:PaulRBerg/sol-compiler-bug.git
2. cd sol-compiler-bug
3. npx @0x/sol-compiler

Context

This has originally occurred in the AZTEC repo, in the "protocol" package on the "feat-coverage" branch, but the behaviour is exactly the same in the bug repo I created.

Your Environment

Tool	Version
@0x/sol-compiler	3.1.0
npm	6.7.0
node	10.15.0

Thanks for a repro. I'm able to repro. Looking into it

[LogvinovLeon]

Ok. So there are two things here:

1. You should use Numbers.sol instead of contracts/Numbers.sol in compiler.json
2. The bug on our end: Fix a bug when combining sol-compiler settings from different sources #1652
