SyntaxError: export declarations may only appear at top level of a module

Hi all!

 

I'm newbie in custom visuals development so sorry for a stupid question may be.

I follow this instruction for creating a new custom visual.

I created the new project using the same way as instruction says. It works fine.

Well, I installed d3 library and added typings using command:

npm install @types/d3@3.5 --save-dev

My little project understands type d3 after that. But it does not work now.

I did a little research and saw the following message in browser console:2018-04-10_08-40-46.png

 

 

As I see the script crashes because export command appears at NOT top level of module.

I will be grateful for any help.

 

Thanks in advance,

Alexander.

What version of d3 did you install?

 

Power BI Visuals Tools support d3v3 only.

We'd recommend to install d3v3:

npm i d3@3.5.5 @types/d3@3.5.36

Hello Ignat!

 

Thank you so much! It works.

I think it will be good to update this section of tutorial on Github.

It contains an example of d3 version 4.9.1 installation.

Thank you once again!

Alexander.
