我在 Mac OS X El Capitan (10.11.4) 上安装了一个新的奥术师副本到/usr/local/phabricator/arcanist.
如果我首先cd进入/usr/local/phabricator/arcanist并运行其中一个bin/arc或只是arc（正如我添加/usr/local/phabricator/arcanist/bin到我的PATH），那么一切都很好。但是，如果我尝试arc lint从系统上的 Rocksdb 目录运行，那么我总是会遇到致命错误，输出如下所示：
$ arc lint --trace
ARGV '/usr/local/phabricator/arcanist/bin/../scripts/arcanist.php' 'lint' '--trace'

If you are not a developer, this almost always means that a library is out of date. For example, you may have upgraded `phabricator` without upgrading `libphutil`, or vice versa. It might also mean that you need to restart Apache or PHP-FPM. Make sure all libraries are up to date and all services have been restarted.
If you are a developer and this symbol was recently added or moved, your library map may need to be rebuilt. You can rebuild the map by running 'arc liberate'. For more information, see:

请注意，我已尝试重新安装并运行它arc liberate，但都没有解决问题。
有人能告诉我我的系统出了什么问题吗？
我还用 Git 检查了我的奥术师确实是正确的并且是最新的：
$ cd /usr/local/phabricator/arcanist
$ git remote -v
origin github.com/phacility/arcanist.git (fetch)
origin github.com/phacility/arcanist.git (push)
$ git status
On branch master Your branch is up-to-date with 'origin/master'. nothing to commit, working directory clean
$ git pull
Already up-to-date.
我也尝试通过这种机制重新安装：
$ cd /usr/local/phabricator
$ rm -rf arcanist libphutil
$ git clone https://github.com/phacility/libphutil.git
$ git clone https://github.com/phacility/arcanist.git
