添加Symfony應用程序時的JSON_ERROR

我剛剛在運行PHP 7.0.14的CentOS安裝程序上安裝了Symfony。但是我有試圖運行symfony new project_name當以下問題：添加Symfony應用程序時的JSON_ERROR

PHP Notice: Use of undefined constant JSON_ERROR_DEPTH - assumed 'JSON_ERROR_DEPTH' in phar:///usr/local/bin/symfony/vendor/guzzlehttp/guzzle/src/Utils.php on line 134

我在網上尋找答案各地檢查，已經嘗試在php.ini中設置phar.readonly = Off

你是如何安裝php 7的？似乎你缺少json擴展名，或者需要啓用它; – hassan

你說得對，@ hassan，我錯過了JSON-exstension。 –

哈桑是正確的，我是錯過了json擴展。通過運行修復它sudo yum install php70u-json
