作曲家安装：json扩展名丢失 [英] Composer installing: the json extension is missing

问题描述

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

c $ c> apt-get install php5-json
所以，我想，它的安装。但奇怪的是，当我写 php -m
它给我一个没有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:

我做错了什么？我还没有在GitHub和Google找到解决方案

推荐答案

您可能需要在 php.ini 文件。要找出命令行PHP的位置，请执行

You probably need to enable the extension in your php.ini file. To find out where that is for command line PHP, do

php --ini

您应该看到一行

加载的配置文件：/path/to/php.ini

Loaded Configuration File: /path/to/php.ini

打开该文件并查找 extension = json.so 。如果它在那里，取消注释。如果没有，添加它。现在你应该看到 json 列出当你 php -m 和作曲家应该工作。

Open that file and look for extension=json.so. If it's there, uncomment it. If not, add it in. Now you should see json listed when you do php -m and composer should work.
