Composer php Laravel 8安装程序错误----“移除vcs”；选项不存在

我最近安装了新的Laravel安装程序，以获得版本8。我遇到以下错误：

| |                             | |
| |     __ _ _ __ __ ___   _____| |
| |    / _` | '__/ _` \ \ / / _ \ |

|______\__,_|_|  \__,_| \_/ \___|_|


                                                          
  [Symfony\Component\Console\Exception\RuntimeException]  
  The "--remove-vcs" option does not exist.               
                                                          

create-project [-s|--stability STABILITY] [--prefer-source] [--prefer-dist] [--repository REPOSITORY] [--repository-url REPOSITORY-URL] [--dev] [--no-dev] [--no-custom-installers] [--no-scripts] [--no-progress] [--no-secure-http] [--keep-vcs] [--no-install] [--ignore-platform-reqs] [--] [<package>] [<directory>] [<version>]

我得到了

[RuntimeException]
SHA384 is not supported by your openssl extension, could not verify the phar file integrity

因此，该过程将是卸载Composer并重新安装

删除：

sudo rm /usr/local/bin/composer

要安装：

curl -sS https://getcomposer.org/installer | sudo php

使作曲家全球化：

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

测试编写器：

composer

最后，我再次安装了laravel

composer global require laravel/installer

composer global require laravel/installer
