How do I use a template literal in an import statement?

Question

When this line is executed:

import stats from `./${process.env.STATS}`

the error below is reported:

Parsing error: Unexpected token `

The module can be loaded successfully with the expression:

const stats = require(`./${process.env.STATS}`);

The import statement seems to require a regular string as it works with the statement:

import stats from './statsdir'

where './statsdir' is the value of process.env.STATS.

Why does the error occur?

I am using version `6.0`. I'm also using `babel-cli` to compile the source files. — gnerkus, Apr 30 '16 at 13:07
if you are using babel, are you loading the correct presets in your .babelrc? — QoP, Apr 30 '16 at 13:07
can you show us your .babelrc and the way you are executing your app? It seems like it's not loading your presets — QoP, Apr 30 '16 at 13:17

@qop this has nothing to do with Babel or presets. It's invalid syntax. — , Apr 30 '16 at 14:37

It seems you found the answer yourself:

Exactly. import needs a string literal. It import location cannot be dynamic.
