進入laravel之後，開始製作自己的頁面才發現Bootstrap Css沒有正確顯示，查了一下資料，雖然不是完全理解，不過我想大概是因為我沒有執行composer install和npm install，laravel需要外掛的一些元件沒有掛上去。
那麼開始執行程式吧！首先我沒有修改任何檔案，下面是cmd執行composer install的結果：
C:\AppServ\www\project\calibreBook
λ composer install
Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Nothing to install or update
Package phpunit/phpunit-mock-objects is abandoned, you should avoid using it. No replacement was suggested.

> @php artisan package:discover
Discovered Package: fideloper/proxy
Discovered Package: laravel/tinker
Discovered Package: nesbot/carbon
Package manifest generated successfully.
到底安裝了什麼，其實我也搞不清楚，不過看到了php Unit，應該是和單元測試相關吧！其他東西就先不管了。
接著要執行npm install，這個時候cmd報錯了，npm不是內部或外部命令(我汗)。
查了一下，原來要執行npm前，還要先下Node.js，Node.js還有兩種版本LTS vs Current(狂汗)，結論是LTS是長期維護版本，非前端專門的工程師，用這個就十分足夠了，Current裡面則會有新功能，專門的前端工程師可能會需要。
npm install執行時間非常長...(我汗)，下面是執行完畢的結果(真的很長@@)

那麼bootstrap到底掛上了沒呢？我看到了bootstrap-sass和jquery，後面還要再試試看才知道。
<link rel="stylesheet" href="/css/app.css">
我開了測試檔案，把上方的這個掛上去就可以看到bootstrap的style了，這個應該是公用的css。
<script src="/js/app.js"></script>
上方的這個應該是公用的js，目前應該包括bootstrap和jquery的js。
到此bootstrap和jquery應該已經掛上了。
