Valet installation fails with file_get_contents(): read of 8192 bytes failed with errno=21 Is a directory

It seems to expect a file but it found a directory instead.

Check your ~/.composer directory. You might need to delete your vendor directory.

i tired to rename it my ~/.composer/vendor to ~/.composer/vendor_old but when i run the command again i get the following message

[ErrorException]
  file_put_contents(~/.composer/vendor/bin): failed to open stream: No such file or directory

``

After you rename it you should run composer install then the composer global require laravel/valet

i don't think we are going in the right direction here, i have no project setup yet, i'm trying to install valet globally , here is the output of composer installafter renaming vendor to vendor_old

MacBook-Pro-de-Ayoub:~ ayoub$ composer install
Composer could not find the config file: /Users/ayoub/.composer/vendor/bin
To initialize a project, please create a composer.json file as described in the https://getcomposer.org/ "Getting Started" section

Also here is the full logs i get when i try to run composer global require laravel/valet -vvv (after canceling the changes is did to the vendor folder)

mv composer.phar /usr/local/bin/composer

composer install will act locally I think.

try composer global install

it is already there

MacBook-Pro-de-Ayoub:~ ayoub$ which composer
/usr/local/bin/composer

Can you explain why should i run composer install ? as i said before i'm not inside a working laravel project yet , i'm configuring my dev environment .

issue solved

I had a COMPOSER variable set to update my PATH variable; to include vendor/bin available to zshrc.

export COMPOSER="/Users/ayoub/.composer/vendor/bin"
export PATH="$COMPOSER:$PHP:$PATH"

So after I renamed the variable to MYCOMPOSER; it no longer threw that error. So it seems maybe internally COMPOSER created a conflict.

Because it will install everything you removed by renaming the vendor directory,
