我尝试使用命令安装Laravel，＆＃34; sudo composer create-project laravel / laravel my_project --prefer-dist ＆＃34;，但我保留得到错误：

[Composer\Downloader\TransportException]                                                                               
  The "https://packagist.org/packages.json" file could not be downloaded: failed to open stream: Network is unreachable

要查看一切是否正常，我运行了命令，＆＃34; composer diagnose ＆＃34;得到以下输出：

除了第一项之外的一切都很好。

使用＆＃34; curl https://packagist.org/packages.json ＆＃34;测试网络元素，显示文件内容：

{"packages":[],"notify":"\/downloads\/%package%","notify-batch":"\/downloads\/","providers-url":"\/p\/%package%$%hash%.json","search":"\/search.json?q=%query%&type=%type%","provider-includes":{"p\/provider-2013$%hash%.json":{"sha256":"e8a58721d48f09fca4bf257fac28558dc991cef7b48c19788e27bff3a99281d4"},"p\/provider-2014$%hash%.json":{"sha256":"b6bc409a370dc08774a2843e4bbf3361673fc5bc70bed785ebdeda390ba346b3"},"p\/provider-2015$%hash%.json":{"sha256":"a8672ac6b29efa52ebd0cd4e4eb96c501fd53cfe3210f840b16d6e9c94323db4"},"p\/provider-2016$%hash%.json":{"sha256":"71c329389ec4548f58a929bb7247bda62442620297b90cb78436de5782eed151"},"p\/provider-2017$%hash%.json":{"sha256":"b080b76a6d9a2f0894c34e9e49bcfa97a746a45b070e4a6db7703241bf11dd66"},"p\/provider-2017-07$%hash%.json":{"sha256":"070467a6b8731c1ad87e110ebcf4aad74fc772f57ac5fe06a22714732e4d2ec8"},"p\/provider-2017-10$%hash%.json":{"sha256":"9f61c57bba06ec280de49be57bba3f6ce133c2bd1de7252d7e8ff7749519cadf"},"p\/provider-2018-01$%hash%.json":{"sha256":"461f6ba8553b9eb3ca1ffcabcf396c94ca2147b497f2d7db859e85749b2912b5"},"p\/provider-2018-04$%hash%.json":{"sha256":"c7cfb560ab198f3194b37a9acbb2b489a45cf48d269ac388a7b862884ad050d3"},"p\/provider-archived$%hash%.json":{"sha256":"afa373e95aa9fa7678612f8c7a961c6373160760005c1f8f41450f2860d933f9"},"p\/provider-latest$%hash%.json":{"sha256":"df4817874d00dfdd1d46dc2c1d92cd77aac2b9178a2115339e8978ee8652fca7"}}}

理论上证明网络和服务器可以看到实际文件。我还通过export命令设置了HTTP和HTTPS代理到公司的代理。

我已经修改了IPv4高于IPv6的优先级。

跑步＆＃34;作曲家clearcache＆＃34;在上述命令没有任何区别之前，也没有更改packagist的存储库。

运行命令＆＃34; curl -sS https://getcomposer.org/installer | php - --check ＆＃34;再次返回输出：

All settings correct for using Composer

有没有人知道我可以做些什么来尝试让这个工作？它仍然是一个网络问题，我不确定Composer正在尝试使用哪个流。

感谢您就此问题提供任何意见。

上面的问题是在环境中设置了一些HTTP_PROXY值之后，尽管运行了在当前实例中设置它们的命令，但它们没有采用。

关闭会话并重新启动它会使环境变量发挥作用，我能够成功安装Laravel！
