无法安装Laravel4

Question

我尝试在Windows 8上安装Laravel4。

我下载了文件，将其解压缩，然后调用“ composer update”，然后收到以下消息：

    PHP Warning:  require(D:\sites\lara\bootstrap/../vendor/autoload.php): failed to open stream: No such file or directory in D:\sites\lara\bootstrap\autoload.php on line 17

Script php artisan clear-compiled handling the pre-update-cmd event returned with an error

如果我尝试通过输入作曲家创建项目laravel / laravel

我有

   - did you forget to enable it when you configured PHP?

感谢您的帮助

Answer 1

杰森·刘易斯是对的。 只需注释掉php.ini中的openssl扩展，再次在cmd中运行命令即可解决您的问题。 无需重新启动PC或服务器。

Answer 2

您不应该打电话给update 。 您应该首先致电install 。

至于create-project方法，我也有同样的问题。 但它消失了。

尝试安装时，请完全参考文档。
