新的电脑安装了PHP、设置好环境变量之后安装了composer,想要通过composer安装Yii2,结果出现了如下报错:
[Composer\Downloader\TransportException]
The "https://packagist.org/packages.json" file could not be downloaded: SSL
operation failed with code 1. OpenSSL Error messages:
error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify
failed
Failed to enable crypto
failed to open stream: operation failed
检查发现php.ini里面的extension=php_openssl.dll已开启,如提示所说问题的原因是证书认证失败。
解决方法:
http://curl.haxx.se/docs/caextract.html 从该网址下载证书文件cacert.pem,然后打开php.ini,找到 openssl.cafile=
添加下载证书文件的位置(例如:openssl.cafile="E:/php-5.6.27/ext/cacert.pem"),问题解决。
