chmod(): Operation not permitted，/vendor/laravel/framework/src/Illuminate/Filesystem/Filesystem.php

1、chmod(): Operation not permitted，/vendor/laravel/framework/src/Illuminate/Filesystem/Filesystem.php 。如图1

图1

    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、原因可能在于切换了 Git 分支的缘故，而并未合并代码。但是 /vender 目录是共用的。重新执行命令：composer install 后，不再报错。如图2
