Cpan
無法安裝 CGI 模組
我在 Amazon EC2 Linux AMI 中安裝 CGI 模組時遇到問題。在 CPAN 安裝過程中，它會失敗。
# Failed test 'write access to CGItest revoked' # at t/tmpdir.t line 30.這是安裝日誌。我在這裡做錯了什麼？

我今天遇到了同樣的問題（也在 Amazon EC2 Linux AMI 上）。失敗的測試是“錯誤的”。（由於“某些平台”上的已知故障，它們以前沒有執行，但由於未知原因，在 2012 年 11 月 2 日發布的 CGI v3.61 中重新啟用）
基本上，測試腳本在測試目錄上執行“chmod 500”（與 TMPDIR 或 /tmp 無關），然後執行“-w $testdir”以查看該目錄之後是否可寫。但當然 root 可以寫入 500 目錄而不會出錯。因此，對於任何以 root 權限安裝 CGI 的人來說，這些測試都應該失敗。
據我所知，這樣做是完全安全的：
