What to do if SQLite3 version error occurs?

# What should I do if a SQLite3 version error is prompted?

On some operating systems (such as `CentOS 7`), running with the `SQLite3` database produces the following error message:

`django.core.exceptions.ImproperlyConfigured: SQLite 3.8.3 or later is required (found 3.7.17).`

This indicates that the `sqlite3` version bundled with the operating system is too old, and the system's `sqlite3` needs to be upgraded.

The following is one method, from [StackOverlow](https://stackoverflow.com/questions/55674176/django-cant-find-new-sqlite-version-sqlite-3-8-3-or-later-is-required-found):

## 1. Download the new version of `SQLite3`

```
wget https://www.sqlite.org/2019/sqlite-autoconf-3290000.tar.gz
```

## 2. Extract the file

```
tar zxvf sqlite-autoconf-3290000.tar.gz
```

## 3. Enter the extracted directory

```
cd sqlite-autoconf-3290000
```

## 4. Configure the installation directory

```
./configure --prefix=$HOME/opt/sqlite
```

## 5. Compile and install

```
make && make install
```

## 6. Specify environment variables

```
export PATH=$HOME/opt/sqlite/bin:$PATH
export LD_LIBRARY_PATH=$HOME/opt/sqlite/lib
export LD_RUN_PATH=$HOME/opt/sqlite/lib
```

## Verification

After completion, you can run the `sqlite3 --version` command to check the current `SQLite3` version.
