JSBI.BigInt is not a function /node_modules/dbus-next/lib/marshallers.js?:255:24

[marcoippolito]

Just importing dbus-next in a new javascript file causes this error:

DBus.js :

import { sessionBus, } from 'dbus-next';

How to solve the problem?

Put this in your webpack config:

resolve: {
  alias: {
    jsbi: path.resolve(__dirname, 'node_modules', 'jsbi', 'dist', 'jsbi-cjs.js')
  }
},

Hi @acrisci Tony! After putting alias in webpack config should I do something else?

Now in webpack.config.js :

resolve: {
    extension: ["*", ".pem"],
    alias: {
        jsbi: path.resolve(__dirname, 'node_modules', 'jsbi', 'dist', 'jsbi-cjs.js')
    }
},

But I still have the same error

This fix has worked for 3-4 people. Make sure the path for the alias is actually pointing to an existing file in the node modules.

[marcoippolito]

The path sbi: path.resolve(__dirname, 'node_modules', 'jsbi', 'dist', 'jsbi-cjs.js') seems correct:

(base) marco@pc01:~/webMatters/vueMatters/GGC/node_modules/jsbi/dist$ ls -lah
total 92K
drwxr-xr-x 2 marco marco 4,0K lug 14 14:45 .

If you're using vue, I think the webpack config is a little different.

https://github.com/dbusjs/mpris-service/issues/45

module.exports = {
  pluginOptions: {
    electronBuilder: {
      chainWebpackMainProcess: config => {
        config.resolve.alias.set('jsbi', path.join(__dirname, 'node_modules/jsbi/dist/jsbi-cjs.js'));
      }
    },
  },
};

[marcoippolito]

I added at the end of webpack.config.js file :

module.exports = {
  pluginOptions: {
    electronBuilder: {
      chainWebpackMainProcess: config => {
        config.resolve.alias.set('jsbi', path.join(__dirname, 'node_modules/jsbi/dist/jsbi-cjs.js'));
      }
    },
  },
 };

But still get this error:

[acrisci]

I think I might try to make JSBI optional so it never gets imported if you don't use it.

[acrisci]

f1e2b4a should make the alias not required if you don't use jsbi compatibility mode. Try that out and see if it fixes it.
