Linux composer安装错误“需要openssl扩展”

Question

I have use 'composer install' command and it say

[Composer\Exception\NoSslException]                                          
  The openssl extension is required for SSL/TLS protection but is not availab  
  le. If you can not enable the openssl extension, you can disable this error  
  , at your own risk, by setting the 'disable-tls' option to true. 

I use on Linux os with php 7.2

How can I fix this?

I already look in php.ini and can't see an extension for openssl.

Answer 1

It's not safe to disable SSL/TLS protection. but if you are confident enough with the working environment try this.

composer config -g -- disable-tls true

then

composer install
