將 wordpress 從倉庫中拉下來時，報了上述錯誤，嘗試各種辦法也找不到具體解決辦法。

背景介紹

由於本地需要搭建一套 wordpress 環境，鑒於自己不太會服務器這塊，只好利用PHP環境一鍵達成的軟件 phpStudy，並從倉庫中落下代碼，啟動。首頁進入，完全沒問題，但是在通過菜單進入時，就各種問題。
使用apache和nginx代理時，報的錯誤還不同。

解決之路

目前網上主要偏向於， apache 配置問題

• apache 配置修改
  1. Find and open the file .http.conf. This will be located in your Apache install folder.
  2. Make a backup of http.conf which you can restore from, if anything were to go wrong
  3. Find the line #LoadModule rewrite_module modules/mod_rewrite.so and remove the hash ‘#’
  4. Locate the block within the directory tags as indicated below and change to:

  ```
    <directory />
      Options All
      AllowOverride All
    </directory>
  ```
  

  5. Find any additional occurrences of the line “AllowOverride None” and change it to “AllowOverride All”.
     6.Finally, restart apache server and your browser. The .htaccess rewriting should now be working for any local website.

但是在嘗試時，依舊沒解決，最后在 .htaccess 這個地方思考良久，才發現自己的配置除了問題

.htaccess

• .htaccess

  在 wordpress 目錄下，居然有該文件，內容如下

    # BEGIN WordPress
    <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.php [L]
    </IfModule>
  
    # END WordPress
  

  發現 RewriteBase 和 RewriteRule 路勁有問題，修改為當前目錄下，便解決了

總結

由於自己的電腦有多種終端，而當一個問題出現時，在不同的終端下，報的錯誤還不相同，因而被迫去理解錯誤的具體含義，具體原因是什么。目前開發到后期，才發現很多錯誤需要自己去看其他功底，比如文件讀取權限，linux命令行，等等。趁着這段時間，不斷鞭笞自己吧。
