Answer 1

For me, the resolution was to compile: bin/magento setup:di:compile. If that seems to do nothing or acts like it completes part of the way through, try increasing your memory limit: php -dmemory_limit=5G bin/magento setup:di:compile. Once I had compiled, I could set the deploy mode.

Answer 2

Try by enabling developer mode

php bin/magento deploy:mode:set developer

Answer 3

Run Following steps to check & then try again:

1. Run "composer install" in magento root
2. please use the -v or -vv option in the command line for debug information.
3. If an extension has no etc/module.xml file then bin/magento fails.
4. If a composer.json has a syntax error.

I hope it helps!

Answer 4

First, remove generated directory and execute

php bin/magento setup:di:compile

provide permission 777 to generated directory.

now please check your Magento commands

Answer 5

Not having a proper content in app/etc/env.php / missing the default db connection array node can also cause the deploy:mode command to be missing from bin/magento, along with many other commands. Check that you have a properly defined .env file, comparing to .env.dist. The behaviour of missing commands, can be replicated quickly (at least on Magento 2.3.6) by emptying .env file as such

<?php
 return [
];

or removing just the default node from the db/connection node

'db' => [
 'table_prefix' => '',
 'connection' => [
 'default' => [

in the .env file.

Answer 6

Just flush your redis cache. This is the problem.

redis-cli FLUSHALL

Answer 7

It might be a permission issue. You can run these commands under your Magento directory :

sudo chmod 775 -R ./generated/ ./var/ ./pub/

• Matthew McLennan: It did not. I got this error: [Symfony\Component\Console\Exception\CommandNotFoundException] There are no commands defined in the "deploy:mode" namespace.
• sami23: @MatthewMcLennan i updated my answer , you can check it
• Jaisa: Never give permission like above,because it should be like sudo chmod 777 -R var/
• Jaisa: Please put slash after var. don't use it before
