Answer 1

I sorted out after long trial and error.

Here are the steps. First, manually install the problematic dependencies:

npm install --save-dev @babel/core
npm install --save-dev @babel/preset-env
npm i @babel/plugin-proposal-numeric-separator

Second, go to file path in which the error is occurring (not in your code dir). In my case:

C:/Users/mahendra/AppData/Roaming/npm/node_modules/powerbi-visuals-tools/node_modules/@babel/preset-env/lib/available-plugins.js

Note that this was found by examining the error message and noticing this line:

Ensure there is an entry in ./available-plugins.js for it. (While processing: "C:/Users/mahendra/AppData/Roaming/npm/node_modules/powerbi-visuals-tools/node_modules/@babel/preset-env/lib/index.js")

Finally, add the following lines to the file:

1. var _pluginTransformNumericSeperator = _interopRequireDefault(require("@babel/plugin-proposal-numeric-separator")); (Import dependency; anywhere above the definition of the export object _default )

2. "proposal-numeric-separator": _pluginTransformNumericSeperator (Add the dependency as a new export in the export object _default by adding a new key value pair)

Note that you may have to replace the path argument to require() with an absolute path to the location of @babel/plugin-proposal-numeric-separator in step 1 above if you are unable to resolve this during your next build.

Enjoy!

Answer 2

The root issue seems to be a problematic version of @babel/plugin-proposal-numeric-separator that powerbi-visuals-tools is depending on.

An alternative to the accepted solution is to install a working version of @babel/plugin-proposal-numeric-separator as a global dependency and then modify the powerbi-visuals-tools to use this instead of its packaged version. See steps below:

1. npm i -g @babel/plugin-proposal-numeric-separator
2. Locate the file that lists dependencies for the failing module. See the accepted answer for instructions, but it seems to be this path for Windows: <userDir>/AppData/Roaming/npm/node_modules/powerbi-visuals-tools/node_modules/@babel/preset-env/lib/available-plugins.js
3. Add the following lines to this file:
   1. var _pluginTransformNumericSeperator = _interopRequireDefault(require("@babel/plugin-proposal-numeric-separator"));
      • This imports our globally installed dependency: place anywhere above the definition of the export object _default
   2. "proposal-numeric-separator": _pluginTransformNumericSeperator
      • Add the dependency as a new export in the export object _default by adding a new key value pair

You should now see the build succeed.

As a note, I'd generally avoid installing global dependencies like this. However, this may be the easiest workaround until the powerbi-visuals-tools package is updated to fix this issue. When this is done, I would recommend uninstalling the global dependency and reinstalling the powerbi-visuals-tools from scratch to undo our changes to the dependency file.
