Unknown collation: 'utf8mb4_0900_ai_ci

Unknown collation: 'utf8mb4_0900_ai_ci' 是在将sql文件导入到mysql数据库时出现的错误。 这个错误是由于mysql数据库不支持utf8mb4_0900_ai_ci这个字符集导致的。要解决这个问题，你需要将sql文件中所有的utf8mb4_0900_ai_ci替换为utf8_general_ci，并将所有的utf8mb4替换为utf8。 这样做可以将字符集统一为mysql数据库支持的字符集，避免出现错误。有相关的资料可以提供参考，特别是关于WordPress导入数据库出现相似错误的解决办法。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
