Dependency issue with postcss-write-svg

[airen]

I run the postcss-write-svg. And I get this error:

Your current PostCSS version is 4.1.16, but postcss-write-svg uses 5.0.10. Perhaps this is the source of the error below.

events.js:85
      throw er; // Unhandled 'error' event
            ^
TypeError: undefined is not a function

I believe you can resolve this by updating PostCSS In your build process.

postcss-write-svg requires PostCSS v5. This error means that you are attempting to run the plugin with an older, incompatible version of PostCSS.

Let me know if it resolves the issue for you.
