This is the same issue as https://dev.clojure.org/jira/browse/CLJS-1682, so all the instructions for reproduce the error can be found in the referenced issue.

Here some specific details of the different errors on different cljs versions:

With cljs==1.9.845 the compilation terminates successfully in both cases (:foreign-libs in build.clj and in deps.cljs) but on executing the generated javascript, an exception is raised:

`
$ node out/main.js
out/src/vendor/greeter.js:3
exports.sayHello = function(name) {

             ^

TypeError: Cannot set property 'sayHello' of undefined

`

With cljs==1.9.908 the compilation terminates successfully in both cases but on executing the generated javascript and other exception is raised:

`
$ node out/main.js
/home/niwi/tmp/greeter/out/testapp/core.js:28
return cljs.core.println.call(null,module$src$vendor$greeter.sayHello("Ciri"));

                                                         ^

at Module.load (module.js:545:32)
at tryModuleLoad (module.js:508:12)

`

And with cljs==1.9.946, using the :foreign-libs in the build.clj file, the following error is raised:

`
$ java -cp cljs.jar:src clojure.main build.clj
module.js:529

throw err;
^

`

Independently of the error, the compilation continues and terminates, and the generated javascript raises the following error (very similat to the error with cljs==1.9.908):

`
$ node out/main.js
/home/niwi/tmp/greeter/out/testapp/core.js:28
return cljs.core.println.call(null,module$home$niwi$tmp$greeter$src$vendor$greeter.sayHello("Ciri"));

                                                                               ^

TypeError: module$home$niwi$tmp$greeter$src$vendor$greeter.sayHello is not a function

at Object.Module._extensions..js (module.js:635:10)
at Module.load (module.js:545:32)
at tryModuleLoad (module.js:508:12)

`

In case of setting the :foreign-lib in the deps.cljs file, the compilation terminates without error but the generated javascript raises the same error as with cljs==1.9.845.

I can confirm this issue persists in version 1.10.339. I had to npm install --save @cljs-oss/module-deps in order to use :foreign-libs with :module-type :es6. I had no :npm-deps, so this seemed an unintuitive extra step.
