bin-dir | Some stuff I 've used on multiple Linux boxes | Continuous Deployment library

I'm trying to deploy my Laravel/Vue.js app on Heroku, but I have an error when I'm trying to push.

Here is the error message :

I'm currently working on an OroPlatform project, which is based on Symfony 4.4 and deployed on Platform.sh.

I'm facing the following issue during the build phase of the deployment:

• My app needs the package symfony/process 4.4.X
• I don't know why, but on the Platform.sh server my app uses the symfony/process package installed for the composer binary installed globally, but this one is a 5.X version
• So, I've got an error and I can't install my app because it uses the 5.X version instead of the 4.X
• That's why I've found a workaround by using Composer 1.9.3 because it uses symfony/process 4.4.X, the same used by my app.

It was working well, but yesterday I have to bump the composer version to latest 1.X due to the Github OAuth token changes: https://nono.ma/github-oauth-token-for-github-com-contains-invalid-characters-on-composer-install

So, I'm still facing this issue with the 4.X version and the 5.X version.

I've tried to install the dependencies of my project this way : composer install -n -o -a but the bug still occurs.

I'm looking for a way to force my project to use the dependencies located in the vendor folder of my app and not the ones installed globally. Here is a screenshot of the issue on the Platform.sh server:

And here is a schema of the path of my app and composer on a Platform.sh server:

While running the Pimcore6.9 along with the symfony4.4 I had spotted some warnings:

The MimetypeGuesser is depricated since symfony4.3 use MimeTypes instead.

I am trying to run Jmeter in Docker. I got Dockerfile and Entrypoint has entrypoint.sh as well added.

I'm working on symfony 2.8 project and I'm new in it. Now I try to upgrade it to the newest version. I found the rector package for update the symfony (rector-prefixed exactly, for older version). I've install it and try to run like it is in documentation: https://github.com/rectorphp/rector, and got this error in the console:

I'm very new to Drupal and trying to install it with composer.

My composer install went well, but now, each time I try to do something, I get this error in the console :

Last days I try to upgrade my project step by step. I have Symfony 2.8, composer 2. Lately I found rector/rector package for upgrading, but there was conflicts when I try to install it. Next I try to install rector/rector-prefixed. It also gives many problems with installation, but after research I've update my php version to 7.4 and it goes good. I've made composer update and install, but in the meantime new error shows up. With AppKernel. Before there was everything good and the app works fine. Now I've got message in the browser: Composer detected issues in your platform: "Your Composer dependencies require a PHP version ">= 7.4.0". "

And in the console after every command (for example: php app/console list) now I'm getting this message:

I am helping someone install E-Directory. It's overall a buggy app.

composer.json

I try to install a specific spreachsheet lib with this command:

composer require phpoffice/phpspreadsheet:1.8.2 (because I have Php5 version)

I have this error :

Your requirements could not be resolved to an installable set of packages.
