通常我会按照以下有关文档的命令来安装 Laravel 5.1:

composer create-project laravel/laravel --prefer-dist

效果很好.

但我在通过 Laravel 安装程序"下的

注意，解决问题后我可以确认通过 Laravel Installer 方式安装比 composer 快.

您在本地安装的 Composer Assets Plugin 正在使用 Composer 已弃用的方法.该插件已修复，因此请运行 composer global update 以获取带有错误修复的最新版本.之后，您应该可以成功运行命令了.

如果这不起作用(因为您可能会在运行上一个命令时遇到相同的错误)，请尝试删除全局供应商目录.运行任何全局 Composer 命令时，它会输出类似将当前目录更改为 XXX"的内容.删除 XXX/vendor 目录，然后尝试运行该命令.

Normally I do install Laravel 5.1 by following this command regarding to documentation:

composer create-project laravel/laravel --prefer-dist

It works fine.

But I read in the documentation under "Via Laravel Installer" also it is possible to install via Laravel Installer, which is much faster than installing via Composer:

laravel new blog

But to use this method I need to run following command once:

composer global require "laravel/installer=~1.1"

When I do run it I get following errors many times

Deprecation Notice: ComposerPackageVersionVersionParser::parseLinks is deprecated. Use ComposerPackageLoaderArrayLoader::parseLinks() instead in phar://C:/ProgramData/Composer/bin/composer.phar/src/Composer/Package/Version/VersionParser.php:226

after many line of same error ./composer.json has been updated appears and it continues with the same line of errors, it ends with following

Loading composer repositories with package information Updating dependencies (including require-dev) Nothing to install or update Generating autoload files

What is wrong with it? Any idea or solution.

My environment: Windows 10, GitBash and cmder console.

Update of composer, I did ran composer self-update also

Snapshot of console

EDIT: Note, I can confirm after solving the issue that the installation via Laravel Installer method is faster than composer.

The Composer Assets Plugin you've installed locally is using a deprecated method of Composer. The plugin is already fixed, so run composer global update to get the latest versions with the bug fix. After it, you should be able to run the command succesfully.

If this doesn't work (as you might get the same error running the previous command), try removing the global vendor directory. When running any global Composer command, it outputs something like "Changed current directory to XXX". Remove the XXX/vendor directory and then try running the command.
