Cannot find module 'estraverse'

[AndyOGo]

I can't run tests locally.
Are all needed modules within devDependencies?

[goto-bus-stop]

Where is it happening? We don't use estraverse directly.

Sorry for my incomplete description.

Actually I just checked out master, did a fresh npm install.
And I get another error TypeError: Cannot read property 'elements' of undefined now 😞

npm run test

and get:

> [email protected] test /Users/axawinterthur/dev/nanohtml
> standard && node tests && npm run test:browser && npm run test:transform-browser && npm run test:babel-browser

Hmh maybe it's cause of http://buble.surge.sh/guide/#-dangeroustaggedtemplatestring- 🤔

[AndyOGo]

Alright I tried to track that down.

Seems that bublè transpiles tagged template lits to MemberExpression and not ArrayExpression as expected here:
Please see AST-Explorer:

Maybe they have also changed this in a newer version 🤔
