我通过yarn安装了scoop。并使用foundation-cli将yarn安装为全局。
执行foundation blocks list时，错误显示：
error fetching file /building-blocks/data/building-blocks.json
undefined:1
SyntaxError: Unexpected end of JSON input

进一步检查后，似乎用验证码阻止了响应。我在Chrome中打开了隐身模式并访问https://foundation.zurb.com/building-blocks/data/building-blocks.json，但它确实显示了验证码屏幕。这是预期的吗？任何解决方法？谢谢！
