快下班的時候準備新搞個小專案本地測試，隨手就是一個composer
composer create-project laravel/laravel laravel --prefer-dist結果一個鮮紅的錯誤
[RuntimeException]
Could not scan for classes inside "/home/vagrant/code/laravel/vendor/sebastian/diff/src/" which does not appear to be a file nor a folder跑去目錄看了下，sebastian/diff 是空的，看來是沒有下載完整。
最近composer映象總是有問題，加上vvv看看吧。
映象確實走的https://packagist.laravel-china.org,但是laravel的每一個包似乎都在報錯，隨便放一兩個上來，
- Installing laravel/tinker (v1.0.7): Loading from cache
Failed to execute unzip -qq '/home/vagrant/code/laravel/vendor/laravel/tinker/5f049e468f89de34bf7c9b7c9fb2ab5d' -d '/home/vagrant/code/laravel/vendor/composer/7e1d1987'

a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of /home/vagrant/code/laravel/vendor/laravel/tinker/5f049e468f89de34bf7c9b7c9fb2ab5d or

The archive may contain identical file names with different capitalization (which fails on case insensitive filesystems)
Unzip with unzip command failed, falling back to ZipArchive class

Unzip with unzip command failed, falling back to ZipArchive class什麼情況？映象出錯了？好吧，去掉映象，再來看下，
vagrant@homestead:~/code$ composer config -g -l
[repositories.packagist.org.type] composer
[repositories.packagist.org.url] https?://repo.packagist.org
[repositories.packagist.org.allow_ssl_downgrade] true現在用官方映象試試，SS要開啟來。（窮人只有免費試用:joy::joy::joy:）
結果還是一樣！！！
怎麼的，今天packagist全掛了？試試安裝個擴充套件包吧
vagrant@homestead:~/code/test$ composer require "overtrue/laravel-wechat"
Using version ^4.0 for overtrue/laravel-wechat
./composer.json has been updated
Loading composer repositories with package information

> @php artisan package:discover

突然想到每次開homestead都會提醒我的
==> homestead-7: A newer version of the box 'laravel/homestead' for provider 'virtualbox' is
==> homestead-7: available! You currently have version '6.0.0'. The latest is version
==> homestead-7: '6.1.0'. Run `vagrant box update` to update.OK.我來升級吧,反正沒事做就死馬當活馬醫吧...
漫長的等待後...
➜ Homestead git:(860e3cd) vagrant box update
==> homestead-7: Checking for updates to 'laravel/homestead'
homestead-7: Latest installed version: 6.0.0
homestead-7: Version constraints: >= 5.2.0
homestead-7: Provider: virtualbox
==> homestead-7: Updating 'laravel/homestead' with provider 'virtualbox' from version
==> homestead-7: '6.0.0' to '6.1.0'...
==> homestead-7: Loading metadata for box 'https://vagrantcloud.com/laravel/homestead'
==> homestead-7: Adding box 'laravel/homestead' (v6.1.0) for provider: virtualbox
homestead-7: Downloading: https://vagrantcloud.com/laravel/boxes/homestead/versions/6.1.0/providers/virtualbox.box
==> homestead-7: Box download is resuming from prior download progress
==> homestead-7: Successfully added box 'laravel/homestead' (v6.1.0) for 'virtualbox'!
➜ Homestead git:(860e3cd) vagrant box list
laravel/homestead (virtualbox, 6.0.0)
laravel/homestead (virtualbox, 6.1.0)現在有兩個box了，這裡吐槽下virtualbox的升級，明明是update,結果是新加了一個box進來，你在搞笑嗎？？這邏輯也是棒棒的！
vagrant也一起升級了算球。
➜ Homestead git:(860e3cd) vagrant version
Installed Version: 2.1.2
Latest Version: 2.1.2
You're running an up-to-date version of Vagrant!重新來啟動homestead吧,又是經過漫長的等待，終於進虛擬機器了（新加了一個virtualbox,啟動會以最新版本啟動，所以初始化比正常啟動要慢！）
重新安裝個laravel專案，終於看到了熟悉的畫面
Writing lock file
Generating optimized autoload files
> Illuminate\Foundation\ComposerScripts::postAutoloadDump
> @php artisan package:discover
Discovered Package: fideloper/proxy
Discovered Package: laravel/tinker
Discovered Package: nunomaduro/collision
Package manifest generated successfully.
> @php artisan key:generate
Application key [base64:VlRjk/MdR/KjDJUyJhC1z4FbOL8HqqrFvo5QUbQUogw=] set successfully.這個小問題終於解決了。
回過頭來想一下，是哪裡出了問題呢？
不知道，沒想明白，那麼問題來了：
