Reconstruction of registry.db of Macports

Question

When installing a package by using macports, my macbook did kernel panic. After kernel panic, my macports told "macports registry malformed". Therefore, I deleted "/opt/local/var/macports/registry/registry.db", and reinstall macports. So, packages are installed in /opt/local/ and cannot reinstall these package by macports, but my macports registry doesn't have a database of installed package.

How to make registry.db?

(My Mac OSX is El Capitan)

没有简单的方法来重建registry.db。你不应该删除数据库。

有时在崩溃后，如果使用写访问权限打开注册表，则可以从日志日志中恢复注册表状态，但如果删除它，则无法执行此操作。

此时您唯一的选择是按照https://guide.macports.org/#installing.macports.uninstalling上的卸载说明操作，然后重新安装所有端口。
