Can't Install Yii2 on Heroku.

[pareekbhagu]

I'm trying to install Yii2-basic-application template on Heroku. But I'm facing dependency/composer issues.

The application runs perfectly on local machine, but while deploying to heroku, it throws a ReflectionClass Error, (Class yii\debug\Module not found). This exception is about yii2-debug module (https://github.com/yiisoft/yii2-debug). I don't know anything about the internal workings of composer. I have run composer update, composer dump-autoload but no help. The files actually exist on the server, which makes me think it might be a problem about class-mapping in composer related files.

I would also appreciate alternate workarounds, as it is critical.

If it is the composer-asset-plugin that is causing it, Isn't there a manual workaround ? Shouldn't it be mentioned somewhere on forums, while Yii team fixes it in the next upcoming version of Yii2, a working solution that can atleast ENSURE that application will install perfectly.

Are you using option --no-dev in composer?

[pareekbhagu]

no. Didn't run composer update with -no-dev option ..my require-dev section is here ..

"require-dev": { "yiisoft/yii2-codeception": "*",

    "yiisoft/yii2-gii": "*",
    "yiisoft/yii2-faker": "*"
},

I moved the yii2-debug from required-dev to required.

Heroku uses composer install with --no-dev as a default. You have debug listed in bootstrap section of Yii application config, but do not have dev-dependencies installed.

You can either:

• move yiisoft/yii2-debug to the require section of composer.json, run composer update, commit composer.lock and push changes to Heroku
• do not use debug-panel on the prod environment.

Choose one of these and push your application again

I shall be so thankful if you could kindly list the exact steps you followed to make the above app running? That way I might get an insight into what am I doing wrong.

• Open composer.json and move yiisoft/yii2-debug, yiisoft/yii2-gii from require-dev to the require section
• composer update
• git add composer.lock composer.json && git commit -m 'updated composer.json'
• git push heroku master

Something like this

@SilverFire I am having an issue with routing on an Advanced Yii2 install. All views other than index return not found. I have been searching with no hope. Just loaded your heroku above, and it too has issues with routing. (all the links result in 404s)

Any ideas?

How is this a valid solution? On production I don't need dev dependencies, so I should be able to install by doing composer install --no-dev. However this results in the error message "ReflectionException : Class yii\debug\Module does not exist".

Yes I have debug listed in the application config, but this is enclosed within if (YII_ENV_DEV) {. So it should never try to load it in.

@omzy It should not be loaded if it's enclosed properly...
