I am currently trying to clone an existing project of mine from github. After clone I run composer install during the process I receive the following error:

Answer 1

Yes as said by @jakehallas . Its not related to what is showing in exception.

Actually if there is any dababase issue or other config varilables issue causes this.

Actually when i tried to change something in database.php i just duplicated same file as database-copy.php. I didn't execpt this causes issue.

After gone through what i have done before i just removed this database-copy.php file its working fine..

Thanks ...

I was typing a CMD in the CLI and accidentally typed it in the app config file. I had to follow this procedure in order to find the problem.

Solution, how to find problem:

• make a backup copy of config folder. try to delete one config at a
• time and try to run composer/artisan command that failed. When you
• find file that failed - search for a row that can possibly fail.
• Reason why it is failed is: You use class constant that is not loaded
• yet. You use class/function that is not loaded yet. etc

Answer 3

In your .env file make sure you have no spaces for values

for example this is allowed

DB_USERNAME=homestead

this is not allowed

DB_USERNAME=home stead

you can wrap the value in quotes if you have spaces.

DB_USERNAME="home stead"

really wish they used json for the .env file, maybe we should request that feature

Answer 4

In my case, a comma is missing in my config file (config/app.php) after I merged my branch to master.

it was a syntax error, but didn't display it.

Answer 5

When composer updating, i think laravel makes some validations.

• Install "unzip" package("sudo apt install unzip") if not installed.
• Check all required extensions such as "mysql", "json", "curl", "xml", "zip", etc. and install("sudo apt install php7.1-mysql") if not installed.
• Check your file/folder permissions.
• Check your ".env" file.
• Check your "config" files.
• Run "composer update" again.

Installing unzip works for me. Good Luck :)

Answer 6

In my case, the missing of PDO extension was the problem. After installing it, the problem was fixed.
