# Troubleshooting

This page contains some advice about errors and problems commonly encountered during the development of Django applications.

## Problems running `django-admin`

### `command not found: django-admin`

django-admin should be on your system path if you installed Django via `pip`. If it’s not in your path, ensure you have your virtual environment activated and you can try running the equivalent command `python -m django`.

### macOS permissions

If you’re using macOS, you may see the message «permission denied» when you try to run `django-admin`. This is because, on Unix-based systems like macOS, a file must be marked as «executable» before it can be run as a program. To do this, open Terminal.app and navigate (using the `cd` command) to the directory where django-admin is installed, then run the command `sudo chmod +x django-admin`.

## Miscellaneous

### I’m getting a `UnicodeDecodeError`. What am I doing wrong?

This class of errors happen when a bytestring containing non-ASCII sequences is transformed into a Unicode string and the specified encoding is incorrect. The output generally looks like this:

    UnicodeDecodeError: 'ascii' codec can't decode byte 0x?? in position ?:
    ordinal not in range(128)

The resolution mostly depends on the context, however here are two common pitfalls producing this error:

- Your system locale may be a default ASCII locale, like the «C» locale on UNIX-like systems (can be checked by the `locale` command). If it’s the case, please refer to your system documentation to learn how you can change this to a UTF-8 locale.
