traverse.clearCache is not a function

[marvinhagemeister]

Input Code

const foo = "foo";
const bar = `asdf ${foo} asd ${foo}`

Babel REPL link

Actual Output

traverse.clearCache is not a function. (In 'traverse.clearCache()', 'traverse.clearCache' is undefined)

Expected Output

const bar = `asdf foo asd foo`

Details

Noticed this bug when playing around on the repl. Only the minify plugin is enabled.

I'm hitting it as well, it's enough to enable "Minify" on any code to make it break.

An updated REPL link (the one from the OP doesn't work for me): https://babeljs.io/repl#?babili=true&browsers=&build=&builtIns=false&spec=false&loose=false&code_lz=G4QwTgBCELwQTAbgFBA&debug=false&forceAllTransforms=false&shippedProposals=false&circleciRepo=&evaluate=false&fileSize=false&sourceType=module&lineWrap=false&presets=babili&prettier=false&targets=&version=7.0.0-alpha.19&envVersion=2.0.0-beta.2

I ran into this problem on my project (mozilla/normandy#1510, mentioned above) and was able to fix it by changing from babel-preset-babili@0.1.4 to the renamed babel-minify-webpack-plugin@0.3.1. That doesn't explain the problem with the repl though.

Also found this while playing around with the online repl. Any updates on this one?
