macOS 中 /usr/local/lib/dtrace 目录的意义是什么？

Question

When trying to remove node modules while uninstalling nodejs, I deleted the whole /usr/local/lib/dtrace directory. How do I recover contents of dtrace directory?

Answer 1

I don't know the significance of the /usr/local/lib/dtrace directory, but mine has the permissions 755 ( rwxr-xr-x ) and only contains one text file named node.d with the permissions 644 ( -rw-r--r-- ).

The comments at the top of that file say:

 * This is the DTrace library file for the node provider, which includes * the necessary translators to get from the args[] to something useful.

You can download a copy of the node.d file here .
