我正试图在我的项目中运行composer安装，但我遇到了以下错误
[Composer'Downloader'TransportException]
The "http://packagist.org/p/provider-2013$43e3f41fbe30a46245103451248f688a727f076a6e90636d19a69a156c17a416.json" file could not be downloaded (HTTP/1.1 400 Received invalid request from Client)
我已经尝试运行composer自我更新，并出现此错误
[Composer'Downloader'TransportException]
The "https://getcomposer.org/version" file could not be downloaded: Failed to enable crypto failed to open stream: operation failed
我在代理服务器后面运行Ubuntu 15.04和apache/php5.6.4/mysql。
我已尝试下载http://curl.haxx.se/ca/cacert.pem并用以下更新了我的php.ini文件
curl.cainfo=/etc/ssl/certs/cacert.pem
openssl.cafile=/etc/ssl/certs/cacert.pem
openssl.capath=/etc/ssl/certs
运行composer diagnose返回此
Checking composer.json: OK
Checking platform settings: OK
Checking git settings: OK
Checking http connectivity to packagist: FAIL
[Composer'Downloader'TransportException] The "http://packagist.org/packages.json" file could not be downloaded (HTTP/1.1 400 Received invalid request from Client)

Checking github.com rate limit: OK

最后openssl_get_cert_locations((返回
- 默认证书文件：/usr/lib/ssl/cert.pem
- default_cert_file_env:SSL_cert_file
- default_cert_dir:/usr/lib/ssl/certs
- default_cert_dir_env:SSL_cert_dir
- default_private_dir:/usr/lib/ssl/private
- default_default_cert_area:/usr/lib/ssl
- ini_cafile:/etc/ssl/certs/cachert.pem
- ini_capath:/etc/ssl/certs
我完全不知道出了什么问题，更不知道如何调试它。
我希望有人能帮助我！
与您相同。我在互联网上找到了解决问题的方法(适用于windows 10(。1-转到文件夹PATH'xampp'apache并运行makecert.bat2-将此脚本添加到composer.json文件
"repositories": [
{
"type": "composer",
"url": "https://packagist.org"
},
{
"packagist": false
}
]
这个问题很可能与某种HTTPS强制有关，因为从上面的composer diagnose来看，HTTP连接测试失败，而HTTPS测试通过：
Checking HTTP connectivity to packagist: FAIL
...
Checking HTTP proxy support for request_fulluri: FAIL
...
Checking HTTPS proxy support for request_fulluri: OK
运行以下代码段(在composer上强制HTTPS(为我解决了问题：
composer config -g repo.packagist composer https://packagist.org
解决方案源
如果你是Linux(Ubuntu(用户，那么执行以下命令来解决：
php -r "print_r(openssl_get_cert_locations());"
wget http://curl.haxx.se/ca/cacert.pem
sudo mv cacert.pem /usr/lib/ssl/certs/cert.pem // Note: Create the cert.pem file under certs folder if does not exist.
也许您可以尝试更改代理。
http://composer-proxy.jp/
这是来自日本的代理人。希望它对你有用。
尝试php composer global self-update
在环境中设置代理，在终端中使用：
export http_proxy=<proxy>:<port>
export https_proxy=<proxy>:<port>
如果linux服务iptables停止
或关闭Windows 上的防病毒、防火墙
如果以上内容都不适用，请尝试删除系统设置的http_proxy环境变量"环境变量"；
尝试composer全局自更新1.4.1
