Get stuck while running test after import hardhat-gas-reporter

hardhat.config.ts から始め、hardhat-gas-reporter の設定を issue に示されている設定と比較します。reporter を import した状態で npm run test を実行し、REPORT_GAS が未設定の場合でもコマンドが停止したままにならないことを確認します。テストが正常に完了すれば変更は完了です。

Version Info:

• hardhat: 2.8.3
• hardhat-gas-reporter: 1.0.7
• OS：macOS Big Sur 11.6

Problem:
I get stuck when I run test after hardhat-gas-reporter was imported in hardhat.config.ts. The log of npm run test is listed below:

Solution:
Try to modify the config of hardhat-gas-reporter with the following configuration:

gasReporter = {
    currency: 'USD',
    gasPrice: 21,
    enabled: (process.env.REPORT_GAS) ? true : false
}
