[ubuntu] Ubuntu 16.04 install php7.0 solve dpkg: error processing package php7.0-common (--configure): post-installation script

因為更新完ubuntu 系統，使用php-cs-fixer 出現 PHP Fatal error: Call to undefined function json_decode() 錯誤。

使用 php -m 看一下是不是特定module沒有載入。

% php -m

看的出來並沒有載入 json module

$sudo apt-cache search php7.0 | grep json                                                                                                                                            

php7.0-json - JSON module for PHP

$sudo apt-get install php7.0-json

結果出現了

dpkg: error processing package php7.0-common (--configure): post-installation script  

嘗試過很多方法最後

apt purge apache2*

apt purge php*

rm -rf /etc/apache2 /etc/php

root@pccm:/var/lib/dpkg/info# rm -rf ./*

root@pccm:/var/lib/dpkg/info# apt-get install --reinstall php7.0

root@pccm:/var/lib/dpkg/info# php --ini

Configuration File (php.ini) Path: /etc/php/7.0/cli

Loaded Configuration File:         (none)

Scan for additional .ini files in: /etc/php/7.0/cli/conf.d

Additional .ini files parsed:      (none)

root@pccm:/var/lib/dpkg/info# php --ini

Configuration File (php.ini) Path: /etc/php/7.0/cli

Loaded Configuration File:         /etc/php/7.0/cli/php.ini

Scan for additional .ini files in: /etc/php/7.0/cli/conf.d

Additional .ini files parsed:      (none)

這裡個 ini 檔是從 /usr/lib/php/7.0 複製到對應路徑的

php-cli 會在每次使用載入module ，php -m 看看有無載入module 。

如果沒有再檢查 php.ini 的設定

# vim /etc/php/7.0/cli/php.ini

加入

root@pccm:/etc/php/7.0/cli# cat php.ini  | grep "^extension"

extension=calendar.so

extension=ctype.so

extension=exif.so

extension=fileinfo.so

extension=ftp.so

extension=gettext.so

extension=iconv.so

extension=json.so

extension=pdo.so

extension=phar.so

extension=posix.so

extension=readline.so

extension=shmop.so

extension=sockets.so

extension=sysvmsg.so

extension=sysvsem.so

extension=sysvshm.so

extension=tokenizer.so

在使用php -m 就會看到載入的module了

root@pccm:/etc/php/7.0/cli# php -m
