安装Composer失败，出现“缺少openssl扩展”错误

Question

I'm attempting to install Composer but I get the following error:

"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 openssl extension is missing, which means that secure HTTPS transfers are impossible. If possible you should enable it or recompile php with --with-openssl"

I have then gone into my php.ini-production and uncommented: "extension=php_openssl.dll"

This still doesn't work though, is there something else I have to do?

Answer 1

I suspect "php.ini-production" is a dummy configuration file suitable for live environments. Do a php -i at the console and find the 'php.ini' path, to see where it is expecting the ini file to be kept. This is normally expecting "php.ini", and may not actually exist - if it does not, copy php.ini-development (or similar) to the location required.

This is near the top of (a very long) output, so you may find redirecting it to a file helpful ( php -i > C:\\phpinfo.txt ).

Answer 2

You will also need to uncomment the extension dir. For example, find this line in your php.ini file:

;extension_dir = "ext"

Remove the semi-colon in front and save the file. I am sure this will work.

Remember to open your php.ini Administrator mode

Answer 3

更改php.ini中的任何内容后，您必须重新启动服务器，请确保首先执行此操作。

Answer 4

in WAMPserver edit this files:

D:\\wamp\\bin\\php\\php5.3.10\\php.ini

or

D:\\wamp\\bin\\php\\php5.4.12\\php.ini (based on version)

Do not use the php.ini in the WAMP server menu. It will not work. Go to the root of your wamp and as indicated above with D as root.

Answer 5

Make a php.ini (eg from php.ini-production ), open it in an editor as admin (!), remove the commenting semicolon ; in front of extension=php_openssl.dll , set the extension_dir correctly, and save the file. After that it should be working. But once again: open and edit the php.ini as admin.

Answer 6

If you are using MAMP on Windows, you need to change the extension for php.ini-development to php.ini Then, paste this line ;extension_dir = "ext" into the php.ini file, before the first extension appear, and uncomment this other line ;extension=php_openssl.dll removing the prefixed semicolon. Dont't forget to restart apache
