我想用argparse打开文件进行阅读.在cmd中,它必须如下所示:my_program.py/filepath

这是我的尝试:

parser = argparse.ArgumentParser()
parser.add_argument('file', type = file)
args = parser.parse_args()

yarn install v0.21.3

首先我认为这可能是代理问题所以我添加了我的公司代理设置:

如何使按钮位于div的底部并同时位于它的中心？

这是我的代码:http: //jsfiddle.net/3QguR/1/

HTML

<div class='Center' align='center'>
    <button class='btn-bot'>button-bottom</button>
</div>

CSS

.Center{
    width:200px;
    height:200px;
    background:#0088cc;
    margin:auto;
    padding:0%;
    position: relative;
    top: 0; left: 0; bottom: 0; right: 0;
    border-radius:5%;
}
.btn-bot{
    position: absolute;
    bottom: 0;

}

我想有两条不同的设计路线：

• 本地主机：3000/登录 - 标准设计身份验证
• localhost:3000/api/login - 使用另一个非标准控制器/api/sessions_controller进行 api 调用的身份验证

devise_for :users, path: '', path_names: { sign_in: 'login', sign_out: 'logout' }  
namespace :api, defaults: { format: :json } do
  devise_for :users,
             path: '',
             defaults: { format: :json },
             path_names: {
               sign_in: 'login',
               sign_out: 'logout',
              },
              controllers: { sessions: 'api/sessions' }
end

new_user_session         GET     /login(.:format)  devise/sessions#new
user_session             POST    /login(.:format) devise/sessions#create
destroy_user_session     DELETE  /logout(.:format) devise/sessions#destroy
new_api_user_session     GET     /api/login(.:format) api/sessions#new {:format=>:json}
api_user_session         POST    /api/login(.:format) api/sessions#create {:format=>:json}
destroy_api_user_session DELETE  /api/logout(.:format) …
