我正在尝试使用 PHP 版本 5.6.* 在我的 Ubuntu 16.04 中安装 composer.

I'm trying to install composer in my Ubuntu 16.04 with PHP version 5.6.*.

我用过:curl -sS https://getcomposer.org/installer |php.但它给我的错误如下:

I used:curl -sS https://getcomposer.org/installer | php. But it is giving me error as follows:

All settings correct for using Composer

我之前没有安装作曲家.

I do not have composer installed previously.

推荐答案

我通过下载 解决了这个问题https://curl.haxx.se/ca/cacert.pem 并在我的 etc/php/5.6/cli/php.ini 和 etc/php 中给出它的路径/5.6/apache2/php.ini.

I solved the issue by downloading https://curl.haxx.se/ca/cacert.pem and giving it's path in my etc/php/5.6/cli/php.ini and etc/php/5.6/apache2/php.ini.

然后运行 ​​sudo service apache2 restart &&sudo apt install composer 工作正常.

Then after running sudo service apache2 restart && sudo apt install composer just worked fine.
