我已经阻止了这个问题好几天，并尝试了很多，谷歌搜索了很多，但没有得到有价值的信息。
我已经完成了所有 phabricator 配置。并且没有扩散问题。我可以正确地朗姆酒 arc diff，但是当我做 arc lan 时，这个问题就出来了。
我也可以玩 git init --bare，然后 git pull，正确推送。git版本是2.7.2。
并且带有 --trace 标志的日志被炸毁：
~/phabricator_test/test $ arc land --trace
ARGV '/mnt/data/arcanist/bin/../scripts/arcanist.php' 'land' '--trace'
