Fecmall 升级 composer update报错：[Composer\Downloader\TransportException] Content-Length mismatch, received 81664 bytes out of the expected 5694137

我的安装场景：

最近一次新安装的fecmall，想要安装 yiisoft/yii2-mongodb,执行命令

composer require --prefer-dist yiisoft/yii2-mongodb

总是报错:

composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)





                                                                             
  [Composer\Downloader\TransportException]                                   
  Content-Length mismatch, received 81664 bytes out of the expected 5694137

排查了好久，最后解决：

打开根目录的：composer.json文件，将

"scripts": {
        "post-install-cmd": "php init --env=Development --overwrite=n"
    },

去掉，重新执行composer命令即可即可，后面发新版，将会去掉这个
