Composer找不到配置文件：C：\ Users \ Username \ AppData \ Roaming \ Composer \ vendor \ bin

Question

我似乎无法使用以下命令安装Laravel：composer create-project laravel/laravel laravel-testing --prefer-dist因为它不断抛出以下错误：

 [InvalidArgumentException]
 Composer could not find the config file: C:\Users\Kieran\AppData\Roaming\Co
 mposer\vendor\bin
 To initialize a project, please create a composer.json file as described in
  the http://getcomposer.org/ "Getting Started" section

以下路径中不存在供应商和 bin 文件夹，因此我在其中创建了文件夹vendor，然后是bin仍然没有运气：

C:\Users\Kieran\AppData\Roaming\Composer\vendor\bin

我做错了什么？

Answer 1

我设法解决了这个问题。我不得不删除composer环境变量。可在此处找到：Control Panel>System>Edit the system environment variables>Environment variables>composer>delete

删除后，我可以运行我想要的命令，没有任何错误，并按预期工作：composer create-project laravel/laravel laravel-testing --prefer-dist
