The latest version can't be installed with node v12.19.0 and npm v6.14.8

Hey @davidmurdoch,

I’ve seen multiple reports of npm failing to install ganache-core lately. Initially I couldn’t reproduce it until I switched to node 12.

This is a pretty weird error, as running npm init -y && npm i ganache-core doesn’t fail. But if you have a project with a package.json and package-lock.json that already have ganache-core, you get this error:

pato@pmbp /t/npmproject-3> npm i
npm ERR! code ENOLOCAL
npm ERR! Could not install from "node_modules/ganache-core/node_modules/web3-provider-engine/node_modules/eth-sig-util/ethereumjs-abi@git+https:/github.com/ethereumjs/ethereumjs-abi.git" as it does not contain a package.json file.

This may be a bug in npm/node, but you could avoid it by upgrading web3-provider-engine, as it doesn’t use a git-based dependency anymore.

We haven’t touched the ethereumjs/ethereumjs-abi repo in a long time, and it does contain a package.json. So I’m inclined to think that it’s npm’s fault.

Fixed in 2.13.1 https://www.npmjs.com/package/ganache-core/v/2.13.1

@davidmurdoch @alcuadrado I was able to fix this by removing: ethereumjs-abi@ prefix from: ethereumjs-abi@git+https://github.com/ethereumjs/ethereumjs-abi.git (all occurencies) which results in: git+https://github.com/ethereumjs/ethereumjs-abi.git in package-lock.json (in your case it would be npm-shrinkwrap.json)

Everything seems to work now.

To reproduce you can do these steps:

1. git pull https://github.com/Synthetixio/kwenta
2. git checkout update-synthetixiojs
3. npm install => fails with error above

now if you open package-lock.json and edit (as described above): ethereumjs-abi@git+https://github.com/ethereumjs/ethereumjs-abi.git (all occurencies) to git+https://github.com/ethereumjs/ethereumjs-abi.git and run npm install again, everything works and package-lock.json is not modified after it.

Created PR for this with a fix: #653
