Magento 2 - How to uninstall module?

Question

How to uninstall module ?

I read this document

But it was not successful, and display below:

php bin/magento module:uninstall SP_Gridthumbs 

SP_Gridthumbs is not an installed composer package

Answer 1

it says in the documentation you linked, this:

This command works only with modules defined as Composer packages.

If you did not install the module via composer, it won't work.
You can only disable it via bin/magento module:disable SP_Gridthumbs.

To remove the module, remove the folder SP/Gridthumbs, remove the record with module = 'SP_Gridthumbs' from the table setup_module and remove any other tables or records added by the install of the module.
Also remove the line with SP_Gridthumbs from app/etc/config.php

composer remove VendorName/VendorExtensionRepository

composer update
php bin/magento setup:upgrade

HERE IS THE STEP BY STEP GUIDE TO UNINSTALL ANY THIRD PARTY MODULE FROM MAGENTO 2 MANUALLY.

Step 1: Remove the module Vendor_Mymodule from app\etc\config.php

Step 2: Drop module tables or columns from database, please check app\code\Vendor\Module\Setup folder for more information

Step 3: Remove the folder app\code\vendor\Mymodule

Step 4: Remove module configuration settings from core_config_data table by running the following query


 DELETE FROM setup_module WHERE module LIKE 'vendor_Mymodule';
Step 5: Run the following command by logging onto your SSH server

But if you have installed the module via composer then you can run the following list of commands by SSHing on the box to uninstall third party module

 php bin/magento module:uninstall -r {{module_name}}
for example

php bin/magento module:uninstall -r Scommerce_GoogleTagManagerPro
-r flag removes module data 

Run the following command once module has been successfully uninstalled.

 php bin/magento setup:upgrade

because this checks for dependencies...

and replace

protected function validate(array $modules)
{
    $messages = [];
    $unknownPackages = [];
    $unknownModules = [];
    $installedPackages = $this->composer->getRootRequiredPackages();
    foreach ($modules as $module) {
        if (array_search($this->packageInfo->getPackageName($module), $installedPackages) === false) {
            $unknownPackages[] = $module;
        }
        if (!$this->fullModuleList->has($module)) {
            $unknownModules[] = $module;
        }
    }
    $unknownPackages = array_diff($unknownPackages, $unknownModules);
    if (!empty($unknownPackages)) {
        $text = count($unknownPackages) > 1 ?
            ' are not installed composer packages' : ' is not an installed composer package';
        $messages[] = '<error>' . implode(', ', $unknownPackages) . $text . '</error>';
    }
    if (!empty($unknownModules)) {
        $messages[] = '<error>Unknown module(s): ' . implode(', ', $unknownModules) . '</error>';
    }
    return $messages;
}

with

protected function validate(array $modules)
{
    $messages = [];
    $unknownPackages = [];
    $unknownModules = [];
    $installedPackages = $this->composer->getRootRequiredPackages();
    foreach ($modules as $module) {
