Generated empty locales file after yargs got an error.

[gucong3000]

We use yargs and y18n:
https://github.com/jedmao/eclint/blob/master/lib/cli.ts#L202

When yargs throw a error by demandCommand(1, 1, i18n('CommandError: Missing required sub-command.'))

yargs will kill main process. and y18n not finsh file write.

After executed this steps, any commands dump parse errors.

/usr/local/lib/node_modules/eclint/node_modules/y18n/index.js:79
    else throw err
         ^

SyntaxError: syntax error in /usr/local/lib/node_modules/eclint/locales/ja_JP.json
    at JSON.parse (<anonymous>)

Any plan? This issue attaches importance to reproduction, interfering with CI operation
