安装composer后，我试图安装larvel，但它给出了ErrorException .please help....
来自composer CMD控制台的数据:-
C:xampphtdocsnew>composer global require "laravel/installer"
Changed current directory to C:/Users/Dell-17/AppData/Roaming/Composer
[ErrorException]
file_put_contents(C:ProgramDataComposerSetupbin): failed to open stream:

您需要递归地设置C:ProgramDataComposerSetup文件夹(包括子目录)的正确权限，以便安装程序可以在其中写入文件。您可以使用一些教程来学习如何做到这一点。
已解决此问题环境变量COMPOSER_HOME应该C:phpcomposer.
