gluejsでlodashが読み込めない問題

原因特定

lib/runner/package-commonjs/index.js:227:

        // require.m[n]['foo'] = { c: 1, m: 'lib/index.js' }
        out.write(
          JSON.stringify(name) + ': ' + JSON.stringify({
            c: index,
            m: list.packages[index].main
          }));
        out.write(',\n');

ここで list.packages[index].main が undefined

distをignoreしてるけどlodash/package.jsonではmain:dist/lodash.jsとしているから問題なのでは…

解決策は --reset-exclude

gluejs --include app --include node_modules/lodash --basepath app --main main.js --out dist/app.js --verbose --reset-exclude ならOK。

副作用

ただし無駄にlodashが二回読み込まれる。lodash/lodash.jsとlodash/dist/lodash.jsで。
