I'm having the same issue, I've opened an issue on github: https://github.com/trufflesuite/truffle/issues/5074

The only solution I founded, for now, it's to downgrade truffle to last v4 (4.1.17)

EDIT: it's also possible to install babel-runtime as a global package to make it work (npm i -g babel-runtime).

See github issue for more updates, they have fixed it! Soon will be released.

How do you downgrade truffle?
Uninstall current version (npm uninstall -g truffle) and install the specific version (npm i -g [email protected]). You can also use the last version installing babel-runtime globally as a workaorund, see github issue
yeah npm i -D babel-runtime fixed it, I installed it locally and as dev dependency
