pip install package from requirements，＆＃34;使用不安全的传输方案＆＃34;

Question

我尝试通过requirements.txt文件中的条目安装django-forms-builder。运行时

pip install -r requirements.txt

我收到错误

django-forms-builder/0.11.1 uses an insecure transport scheme (http). Consider using https if  has it available
django-forms-builder/ uses an insecure transport scheme (http). Consider using https if  has it available
Could not find any downloads that satisfy the requirement django-forms-builder==0.11.1 (from -r requirements.txt (line 33))

单独在需求文件之外安装它时，它可以工作

pip install django-forms-builder

那么我怎样才能强制要求接受它呢？
