Composer 安装:缺少 json 扩展

2022-01-21 00:00:00 json linux php composer-php

我在 Linux 终端中写道:curl -s https://getcomposer.org/installer |php它说:

I wrote in Linux Terminal: curl -s https://getcomposer.org/installer | php It said:

#!/usr/bin/env php Some settings on your machine make Composer unable to work properly. Make sure that you fix the issues listed below and run this script again: The json extension is missing. Install it or recompile php without --disable-json

我这样做了:apt-get install php5-json所以，我认为，它已安装.但奇怪的是，当我写 php -m它给了我一个没有 json 的列表:

I did this: apt-get install php5-json So, I think, it's installed. But the strange thing is, when I write php -m It gives me a list without json:

[PHP Modules] bcmath bz2 calendar Core ctype date dba dom ereg exif fileinfo filter ftp gettext hash iconv libxml mbstring mhash openssl pcntl pcre Phar posix Reflection session shmop SimpleXML soap sockets SPL standard sysvmsg sysvsem sysvshm tokenizer wddx xml xmlreader xmlwriter zip zlib [Zend Modules]

当我写 php5-fpm -m它发送这个:

[PHP Modules] bcmath bz2 calendar cgi-fcgi Core ctype curl date dba dom ereg exif fileinfo filter ftp gettext hash iconv json libxml mbstring mcrypt mhash mysqli openssl pcre PDO pdo_mysql Phar posix Reflection session shmop SimpleXML soap sockets SPL standard sysvmsg sysvsem sysvshm tokenizer wddx xml xmlreader xmlwriter zip zlib [Zend Modules]

我做错了什么?我在 GitHub 和 Google 上都没有找到解决方案

What am I doing wrong? I haven't found the solution at GitHub and Google

推荐答案

我遇到了同样的错误，但不同的是，当我运行 php -m 时 json模块未列出，所以我只是使用以下命令安装了 json PHP 模块:

I encountered the same error, but the difference was that when I ran php -m the json module was not listed, so I just installed json PHP module using the command below:

sudo yum install php-json

错误已修复，我可以安装 composer.我使用的是 CentOS 8 流，PHP7.2.

the error was fixed and I was able to install composer. I was using CentOS 8 stream, PHP7.2.
