ts-jest fails to import .ts modules from outside project root

• Issue

ts-jest throws an error whenever a test utilizes a module from outside the project root.

ReferenceError: Unknown plugin "transform-es2015-modules-commonjs" specified in "base" at 0, attempted toresolve relative to "/home/colin/localdev/ts-jest-error/common"

      at node_modules/babel-core/lib/transformation/file/options/option-manager.js:180:17
          at Array.map (<anonymous>)

• Expected behavior

TS files should be correctly imported even from outside the project.

• Link to a minimal repo that reproduces this issue

cd main && npm install && npm test

Anyone know any more recent updates on this issue? I know Babel 7 is released now.

@lyy011lyy Works for me too.

I also had to set moduleDirectories in my jest config to something like this:

"moduleDirectories": [
	"node_modules",
	"main/node_modules"
],
