I want install an extension: Magento 2

Open Source (CE)

WebP Optimized Images

Component name: jajuma/module-webpimages

Versions: 2.1.8

and tried to install with the installation sheet:


I have the following questions: When I do point 2 I will get the following message:

<oshopat01@vm30:/www$ bin/magento maintenance:enable bash: agoshopat01@vm30:/www$: No such file or directory <op.at$ bash: bin/magento: No such file or directory bash: bash:: command not found

How can start point 4 to 6? 4. Update the composer.json file in your Magento project with the name and version of the extension. 5. Verify that the extension installed properly. 6. Enable and configure the extension.

  • Update your composer.json file: is it correct that I must insert in the file composer.json at "require": the following: jajuma/module-webpimages:2.1.8

Here my composer.json file: https://www.dropbox.com/s/hsv8xs3wb4t49up/composer.json?dl=0

Must I start the command on the Server? composer require jajuma/module-webpimages:2.1.8

Where must I insert the public und private Key ?

Which command must I use and activate instead bin/magento module:status J2t_Payplug.

For the registration and compiling I think I must use the same command linke in the guide? bin/magento setup:upgrade and bin/magento setup:upgrade

Hope someone can help me there kindly regards
