1. chmod(): Operation not permitted, /vendor/laravel/framework/src/Illuminate/Filesystem/Filesystem.php. See Figure 1.
PHP
public function replace($path, $content)
{
// If the path already exists and is a symlink, get the real path...
clearstatcache(true, $path);
$path = realpath($path) ?: $path;
$tempPath = tempnam(dirname($path), basename($path));
// Fix permissions of tempPath because `tempnam()` creates it with permissions set to 0600...
chmod($tempPath, 0777 - umask());
file_put_contents($tempPath, $content);
rename($tempPath, $path);
}
2. The cause might be switching Git branches without merging the code. However, the /vendor directory is shared. After running the command: composer install again, the error no longer occurs. See Figure 2.
