先試一試
wget http://curl.haxx.se/ca/cacert.pem
curl -sS https://getcomposer.org/installer | php -- --cafile=cacert.pem
安裝的php，YII2.0框架，PHP版本高於5.4,調用這個命令的時候出問題了。
composer global require "fxp/composer-asset-plugin:1.0.0"
彈出這樣的問題
-
Changed current directory to /home/litianci/.composer -
./composer.json has been updated -
Loading composer repositories with package information -
The "https://packagist.org/packages.json" file could not be downloaded: SSL operation failed with code 1. OpenSSL Error messages: -

看問題是SSL的驗證問題，網上搜索了很久沒有解決.
下面是來自某被牆的網頁的快照。沒辦法，貼網址也無效。
經過原因查找，在驗證證書的時候出現問題，是本地ssl判別證書太舊，導致報ssl證書錯誤
解決方案一、
下載新的ssl本地判別文件
wget http://curl.haxx.se/ca/cacert.pem
並更名爲ca-bundle.crt放置到默認目錄。如果該目錄不存在可以創建。
mv cacert.pem ca-bundle.crt | mv ca-bundle.crt /etc/pki/tls/certs/
或者curl –cacert cacert.pem 方式指定調用
然後無意中更改了一下xampp-linux-x64-5.6.8-0-installer.run爲一個老的版本xampp-linux-x64-1.8.3-5-installer.run，竟然可以使用了，你不妨換換版本的。
我在deepin2014.3，64bit操作系統下測試成功解決該error.
解決方案二、[版本太老，不建議用]
借鑑 http://pkg.phpcomposer.com/ 。感謝分享。
修改~/.composer/config.json,添加
-
{ -
"repositories": [ -
{"type": "composer", "url": "http://pkg.phpcomposer.com/repo/packagist/"}, -
{"packagist": false} -
]}
最終是這樣子的。
-
{ -
"config": { -
-
}, -
"repositories": [ -
{"type": "composer", "url": "http://pkg.phpcomposer.com/repo/packagist/"}, -
{"packagist": false} -
]}
最終測試可以使用。
解決方案三[完美解決]
參考：https://github.com/composer/composer/issues/3346
First: Check certificate file location which will be in default_cert_file key, you will found it in openssl_get_cert_locations() its php openssl function:
找到驗證文件在哪裏？
這個發現在
/opt/lampp/share/openssl/cert.pem
-
$ php -r "print_r(openssl_get_cert_locations());" -
Array -
( -
[default_cert_file] => /opt/lampp/share/openssl/cert.pem -
[default_cert_file_env] => SSL_CERT_FILE -
[default_cert_dir] => /opt/lampp/share/openssl/certs -
[default_cert_dir_env] => SSL_CERT_DIR -
[default_private_dir] => /opt/lampp/share/openssl/private -
[default_default_cert_area] => /opt/lampp/share/openssl -
[ini_cafile] => -
[ini_capath] => -
)
Second: Download http://curl.haxx.se/ca/cacert.pem:
$ wget http://curl.haxx.se/ca/cacert.pem
Third: Copy certificate PEM file into default_cert_file location:
$ sudo mv cacert.pem /opt/lampp/share/openssl/cert.pem
My php-cli is under XAMPP and default_cert_file maybe point to some place that is different than this.
Fourth：Restart xampp:
$ sudo /opt/lampp/xampp restart
I hope anything after that should goes fine with you brothers.
