Composer在代理后面不起作用

Question

I'm trying to download Laravel on Ubuntu 16.04, but I'm having troubles trying to get Composer to work on our network. I believe that the issue is either related to our proxy server or a firewall, both of which (unfortunate) are managed by our parent organisation.

I'm trying to run this command:

sudo composer global require "laravel/installer"

Which gives me this error:

Changed current directory to /home/administrator/.composer

[Composer\Downloader\TransportException]
The "https://packagist.org/packages.json" file could not be downloaded: failed to open stream: Cannot assign requested address

require [--dev] [--prefer-source] [--prefer-dist] [--no-plugins] [--no-progress] [--no-update] [--update-no-dev] [--update-with-dependencies] [--ignore-platform-reqs] [--sort-packages] [-o|--optimize-autoloader] [-a|--classmap-authoritative] [--] [<packages>]...

When I run composer diag , I get the following output:

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: failed to open stream: Cannot assign requested address
Checking https connectivity to packagist: FAIL
[Composer\Downloader\TransportException] The "https://packagist.org/packages.json" file could not be downloaded: failed to open stream: Cannot assign requested address
Checking github.com rate limit: FAIL
[Composer\Downloader\TransportException] The "https://api.github.com/rate_limit" file could not be downloaded: failed to open stream: Connection refused
Checking disk free space: OK

Now, I've run this command to set the proxy:

export HTTP_PROXY="http://proxy.<url>:8080"

I've also modified /etc/profile to add in the following information:

export HTTP_PROXY_REQUEST_FULLURI=0 # or false
export HTTPS_PROXY_REQUEST_FULLURI=0 #

And I've disabled ipv6 (in /etc/sysctl.conf ), as I noticed that has caused issues in the past:

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1 

Which works (as apt-get uses it), but I can't seem to get curl to work at all. Is there another variable that I should be setting?

您需要在SO中建立环境变量http_proxy = http：// username：password @ ip：port和https_proxy = http：// username：password @ ip：port
