我正在使用sqlite fts5创建一个虚拟表，并收到以下错误消息：SQL逻辑错误没有这样的模块：FTS5.下面是我的代码：在VS 2017中使用包管理器，我已经下载了SQLite和SQLite FTS5。

private static void CreateReport()
    {
        try
        {
            using (SQLiteConnection sqliteConnection = new SQLiteConnection(DataSources.LocalConnectionString()))
            {
                sqliteConnection.Open();
                sqliteConnection.EnableExtensions(true);
                string commandText = "CREATE TABLE IF NOT EXISTS JReport(JRId INTEGER PRIMARY KEY, IDId INTEGER, CaseId INTEGER, BoxName TEXT, JRText TEXT, JRFormatted TEXT)";
                string commandText1 = "CREATE VIRTUAL TABLE IF NOT EXISTS DReport USING FTS5(JRId, CaseId, BoxName, CONTENT = 'JReport', CONTENT_ROWID = 'JRId')";
                string commandText2 = "CREATE TRIGGER DocRepo AFTER INSERT ON JReport BEGIN INSERT INTO DReport(RowId, JRId, CaseId, BoxName) VALUES(NEW.JRId, NEW.CaseId, NEW.BoxName) END";
                using (SQLiteCommand sqliteCommand = new SQLiteCommand(commandText, sqliteConnection))
                {
                    sqliteCommand.ExecuteNonQuery();
                    sqliteCommand.Dispose();
                }
                using (SQLiteCommand sqliteCommand = new SQLiteCommand(commandText1, sqliteConnection))
                {
                    sqliteCommand.ExecuteNonQuery();
                    sqliteCommand.Dispose();
                }
                using (SQLiteCommand sqliteCommand = new SQLiteCommand(commandText2, sqliteConnection))
                {
                    sqliteCommand.ExecuteNonQuery();
                    sqliteCommand.Dispose();
                }
                sqliteConnection.Close();
            }
        }
        catch (Exception ex)
        {
            MessageBoxEx.Show("An error has occurred while creating the Report table, the original error is: " +
                ex.Message, "Report", MessageBoxButtons.OK, MessageBoxIcon.Error);
        }
    }
