通过composer InvalidArgumentException安装laravel

Question

我想安装laravel 4.x，正如您所知，我必须使用composer
我尝试过：
composer create-project laravel/laravel d:xampphtdocslaravel

  [InvalidArgumentException]
  Could not find package laravel/laravel with stability stable.

create-project [-s|--stability="..."] [--prefer-source] [--prefer-dist] [--repository-url="..."] [--dev] [--no-dev] [--no-plugins] [--no-custom-installers] [--no-scripts] [--no-progress] [--keep-vcs][--no-install] [package] [directory] [version]

我已经从github repo下载了laravel，然后尝试了这个：
composer install
这次我得到了：

Loading composer repositories with package information
Installing dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.
  Problem 1
    - The requested package laravel/framework could not be found in any version, there may be a typo in the package name.
Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting
   see <https://groups.google.com/d/topic/composer-dev/_g3ASeIFlrc/discussion> for more details.
Read <http://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.

我正在使用：

Apache 2.4.7
PHP 5.5.6

由xampp-win32-1.8.3-1-VC11安装在win8 64位上

请帮我

谢谢

Answer 1

您忘记添加"--preferred dist".所以在您的情况下，您必须使用：

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

以便使其发挥作用。因此，只需从d:\examplep\htdocs\laravel中删除所有文件，然后按照以下命令对cmd重试（我猜您使用的是Windows！）：

cd d:xampphtdocslaravel
composer create-project laravel/laravel --prefer-dist

我认为这对你来说应该很好

最后我找到了答案，这一切都是关于composer和我的代理设置之间的问题，导致了这个问题。

我已经解释了composer自更新TransportException 中的问题和解决方案

在修复之后，composer完全安装了laravel 4，没有任何问题。

感谢大家

您安装composer时没有任何错误吗？我想我以前也遇到过同样的错误，问题出在作曲家的安装上。
