Question

我正在尝试使用Ubuntu 16.04在我的PHP version 5.6.*中安装作曲家。

我用过：curl -sS https://getcomposer.org/installer | php。但它给我的错误如下：

All settings correct for using Composer

The "https://getcomposer.org/versions" file could not be downloaded: failed to open stream: Connection refused

The download failed repeatedly, aborting.

我之前没有安装过composer。

Answer 1

我通过下载https://curl.haxx.se/ca/cacert.pem并在etc/php/5.6/cli/php.ini和etc/php/5.6/apache2/php.ini中提供了该路径来解决了这个问题。

然后在运行sudo service apache2 restart && sudo apt install composer后工作正常。

Answer 2

看起来主机上的PHP / openssl配置错误。

我的工作站是Ubuntu 16.04.3，php 7.0.22和openssl-1.0.2g - 安装程序工作正常。

尝试禁用TLS：

curl -sS https://getcomposer.org/installer | php -- --disable-tls

Answer 3

这是由我的卡巴斯基互联网安全引起的我通过禁用KIS临时来修复它

您可以尝试一下。

Answer 4

打开终端并运行php -r "var_dump(openssl_get_cert_locations());"

请注意default_cert_file的位置。可能会说\usr\local\ssl\cert.pem 验证该文件存在。如果没有，请从https://curl.haxx.se/ca/cacert.pem下载cacert.pem文件，并将其放置在/usr/local/ssl

中的某个位置。

您现在拥有的文件是usr/local/ssl/cacert.pem

打开您的php.ini并添加文件openssl.cafile=cacert.pem

的位置

安装作曲家

运行composer config --global cafile "/usr/local/ssl/cacert.pem"

Answer 5

我不小心清空了以下文件的内容后，在使用Laravel Homestead时遇到了这个问题：/etc/ssl/certs/ca-certificates.crt

为我修复的问题是：

sudo apt-get purge ca-certificates 
sudo apt-get install ca-certificates

将导出代理从https更改为http

打开终端

    echo $https_proxy
// Change export proxy from 
    https_proxy=https://192.168.0.10:8080/
// to 
   https_proxy=http://192.168.0.10:8080/

cmd :: https_proxy=http://192.168.0.10:8080/

Composer安装失败
