安装Windows版Composer-无法找到包装器"https" [英] Installing Composer for Windows - unable to find wrapper "https"

我正在尝试使用命令行通过以下调用安装Composer for Windows:

I am trying to install Composer for Windows using the command line with the following call:

php -r"readfile( https://getcomposer.org/installer );" | php

php -r "readfile(https://getcomposer.org/installer);" | php

但是，我收到此错误消息:

However, I get this error message:

警告:readfile():无法找到包装器"https"-在配置PHP时您是否忘记启用它?在第1行的命令行代码中

我已经取消对php5.5.12目录中的; extension = php_openssl.dll"行的注释，重新启动了浏览器，并尝试了其他变体.当我仅使用https中的's'运行命令时，我得到:

I have already uncommented the ";extension=php_openssl.dll" line in the php5.5.12 directory, restarted the browser, and tried other variants. When I run the command with just the 's' in https dropped, I get:

计算机上的某些设置使Composer无法正常工作.确保您解决了以下所列问题，然后再次运行此脚本:

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:

openssl扩展名丢失，这意味着无法进行安全的HTTPS传输.如果可能的话，您应该启用它或使用--with-openssl

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

我曾尝试在多个地方添加--with-openssl标志，但似乎并没有解决问题.

I've tried including this --with-openssl flag at various places but it doesn't seem to be doing the trick.

推荐答案

这听起来好像您的安装尚未启用openssl.

This sounds like your installation hasn't got openssl enabled.

找到您的php.ini文件(在Windows上，该文件可能与php.exe(在我的计算机上为c:\php)在同一位置.

Locate your php.ini file (on Windows this is probably in the same place as the php.exe (c:\php on my machine).

在您喜欢的编辑器中打开它，然后找到行

Open it in your favourite editor, and locate the line

;extension=php_openssl.dll

删除分号

extension=php_openssl.dll

HTTPS现在应该可以在php中为您工作.

HTTPS should now work for you from within php.
