[53] Release 0.8.4 not updated

I updated nuxt to 0.8.4 but the lib/nuxt.js is not the same as the github tag. I´m trying to use the new option srcDir. I already deleted the node_modules and yarn.lock, I tried to install using npm and yarn.

My local/installed file: lines 51 to 55

// Env variables
this.dev = this.options.dev
this.dir = (typeof options.rootDir === 'string' && options.rootDir ? options.rootDir : process.cwd())
// If store defined, update store options to true
if (fs.existsSync(join(this.dir, 'store', 'index.js'))) {

https://github.com/nuxt/nuxt.js/blob/v0.8.4/lib/nuxt.js

 // Env variables
 this.dev = this.options.dev
 this.dir = (typeof options.rootDir === 'string' && options.rootDir ? options.rootDir : process.cwd())

 // If store defined, update store options to true
 if (fs.existsSync(join(this.srcDir, 'store', 'index.js'))) {
