已经开了,先用压缩包安装的方式试试看.

应该不存在翻墙问题,直接访问 https://packagist.org/packages.json 显示:

{"packages":[],"notify":"\/downloads\/%package%","notify-batch":"\/downloads\/","providers-url":"\/p\/%package%$%hash%.json","search":"\/search.json?q=%query%","provider-includes":{"p\/provider-active$%hash%.json":{"sha256":"25de36590a8cacdc8018f277a7c1d58cdfa564b629576ddde87b53671b82198a"},"p\/provider-archived$%hash%.json":{"sha256":"1c86ef1e1a3f96dff2e70d637e9806674e5b3f4105ed1f294b78344a4564f6bb"},"p\/provider-latest$%hash%.json":{"sha256":"23b2b0c9fde2cd919c89ad5631b337dfc68994430440969a90ccaaffbafa7144"},"p\/provider-stale$%hash%.json":{"sha256":"ee221c2d8b3a79d9b391c3e83aed0ec45df8684b64ab03ee94bc3162d402cabd"}}}
