本文记录了在ThinkPHP中生成二维码时遇到的问题，以及在解决过程中碰到的Composer扩展安装错误。作者在CMD中尝试安装php_fileinfo.dll扩展，但遇到了未开启的错误。尝试多种解决方案，如修改composer.json、调整镜像源，最终发现可能是由于Composer版本与PHP版本不匹配导致。升级Composer后，问题得到解决，成功安装了所需的二维码插件。

今天写一个二维码生成
这个是正确的，但是重要是下面

我在cmd里面安装的

Using version ^1.0 for aferrandini/phpqrcode
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - phpoffice/phpspreadsheet 1.6.0 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
    - phpoffice/phpspreadsheet 1.6.0 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
    - Installation request for phpoffice/phpspreadsheet (installed at 1.6.0) -> satisfiable by phpoffice/phpspreadsheet[1.6.0].

  To enable extensions, verify that they are enabled in your .ini files:
    - E:\phpstudy\PHPTutorial\php\php-7.2.1-nts\php.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

Installation failed, reverting ./composer.json to its original content.

这个意思是phpini中的 extension=php_fileinfo.dll没有开启，开启重启，然后还报哪个错，说我没有开启
找了找要安装这个插件

composer require aferrandini/phpqrcode

这个，将这个添加进去
随即出现错误

  [Composer\Downloader\TransportException]

重试了很多次都没有成功
有说让在composer.json里面添加这个的

"packagist": {
        "type": "composer",
        "url": "https://packagist.laravel-china.org"
    },

有说让尝试镜像问题，取消镜像

composer config -g repos.packagist composer https://php.cnpkg.org
//然后把默认的 secure-http 改成false；运行代码；
composer config -g secure-http false

弄了半天弄不明白，本人对英文不够了解，看了半天，还是第一个的那个报错，偶尔翻起，看到了版本问题，是不是composer的版本，我用的php版本比较高，就去试了试

composer install --ignore-platform-reqs
或者
composer update --ignore-platform-reqs

然后就开始下载了

默认也将我要安装的二维码插件安好了，完后
