作曲更新不運行

Question

當我運行作曲家更新失敗，則會顯示錯誤：

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

連接被拒絕

如果我訪問從我的瀏覽器，它經過的URL，當我嘗試wget的或捲曲從我的終端的URL它顯示錯誤：

--2017-02-05 20:41:58-- https://packagist.org/packages.json 
Connecting to 127.0.0.1:8888... failed: 
Connection refused. 

--2017-02-05 20:41:58-- https://packagist.org/packages.json 
Connecting to 127.0.0.1:8888... failed: Connection refused. 

，我認爲它的東西代理連接，但我似乎無法解決問題。

幫助將appriciated！我似乎無法通過這個錯誤

Answer 1

Am on Ubuntu Linux 16.04, and below is what i had to do to fix the issue, as i mentiond earlier its some problem with proxy settings.

步驟1

• 轉到系統設置
• 網絡
• 網絡代理
• 它更改爲無
• 最後單擊系統適用

步驟2

• 打開終端並鍵入以下命令。
  unset https_proxy && unset socks_proxy && unset ftp_proxy

最後重新啓動您的系統。上面的解決方案解決了我的問題。

Answer 2

行using proxy 127.0.0.1:8888建議您的系統有問題。我可以猜測這是一個非常積極的殺毒軟件。您應該沒有理由在端口8888上連接到本地主機，除非您通過代理連接必須連接到。你能做什麼？檢查防病毒設置並關閉通過HTTPS進行的安全連接檢查。
