在终端的Mac OS上，当我输入twilio登录时，我得到：
» Installing keytar ...
» Secure credential storage failed to load.
Alternatively, twilio-cli can use credentials stored in environment variables:
# OPTION 1 (recommended)
TWILIO_ACCOUNT_SID = your Account SID from twil.io/console
TWILIO_API_KEY = an API Key created at twil.io/get-api-key
TWILIO_API_SECRET = the secret for the API Key
# OPTION 2
TWILIO_ACCOUNT_SID = your Account SID from twil.io/console
TWILIO_AUTH_TOKEN = your Auth Token from twil.io/console
Once these environment variables are set, a twilio-cli profile is not required to move forward with installation.
但是，我确实尝试通过键入以下语句来设置环境变量，但它仍然不起作用（当然，我将字符串替换为实际值）：
export TWILIO_ACCOUNT_SID="abcd"
export TWILIO_AUTH_TOKEN="efgh"
