Question

我在http代理后面，想要使用sudo port selfupdate更新macports。但它总是失败，输出如下：

$ sudo port -d selfupdate
DEBUG: Copying /Users/simon/Library/Preferences/com.apple.dt.Xcode.plist to /opt/local/var/macports/home/Library/Preferences
DEBUG: MacPorts sources location: /opt/local/var/macports/sources/rsync.macports.org/release/tarballs

rsync error: error in socket IO (code 10) at /SourceCache/rsync/rsync-42/rsync/clientserver.c(105) [receiver=2.6.9]
Command failed: /usr/bin/rsync -rtzv --delete-after rsync://rsync.macports.org/release/tarballs/base.tar /opt/local/var/macports/sources/rsync.macports.org/release/tarballs

    while executing

Error: /opt/local/bin/port: port selfupdate failed: Error synchronizing MacPorts sources: command execution failed

显然问题是rsync没有连接到服务器，所以我单独尝试了rsync，它给了我类似的结果。

$ sudo /usr/bin/rsync -rtzvvv --delete-after rsync://rsync.macports.org/release/tarballs/base.tar /opt/local/var/macports/sources/rsync.macports.org/release/tarballs
opening tcp connection to rsync.macports.org port 873

_exit_cleanup(code=10, file=/SourceCache/rsync/rsync-42/rsync/clientserver.c, line=105): about to call exit(10)

我确实设置了我的RSYNC_PROXY环境变量并且代理正在运行，但是根据rsync的输出，它似乎没有使用我给它的代理但是直接尝试连接而不是。有人可以帮忙吗？谢谢！

如果需要，可以提供更多信息。

$ echo $RSYNC_PROXY
127.0.0.1:3128
$ curl -x localhost:3128 http://rsync.macports.org:873/

问题解决了。

事实证明sudo确实将RSYNC_PROXY环境传递给rsync。要保留环境sudo，请接受-E选项：

-E（保留环境）选项将覆盖env_reset sudoers中的选项（5））。它仅在匹配时可用 command具有SETENV标记或setenv选项在sudoers（5）中设置。

即使RSYNC_PROXY设置，rsync代理也无法正常工作
