+# troubleshooting
+in case you get some weird error or behaviour, before filing any issue, the
+easiest is to make sure the plugin is compiled with the same revision as the
+Nushell you are using!
+```nushell
+use scripts/deps.nu; deps --current
+```
+and then you can come back to the [*installation*](#installation) section.
+
+> **Note**
+> of course, this will not work if the version of Nushell you are using is too
+> old, because then the state of `nu_plugin_explore` will be too recent for
+> everything to compile properly...
