Hello everyone. I’m new to the Julia community and in the process of going through various tutorials.

During a packages update to the [Julia-DataFrames-Tutorial](https://github.com/bkamins/Julia-DataFrames-Tutorial), I obtained a _segmentation fault_ and the update aborts.

```julia

ERROR: Error building `TimeZones`:

```

**What is the proper way to recover from this?** My first instinct was to delete the directory and clone Bogumil’s repository and start again, or maybe adding the **`TimeZones`** package again, but I’m curious to know if there is a more appropriate way. Thanks for your help!

I would also delete stuff first, then if the problem persists report an issue for TimeZones.
