无法在shiny server pro上创建身份验证

我正在使用shiny server pro托管我的shiny应用程序,并希望为用户访问它创建身份验证。

我运行下面的代码来创建用户名,并得到以下错误。

# sudo /opt/shiny-server/bin/sspasswd /etc/shiny-server/myproject/passwd admin

错误:密码文件不存在;请使用-c创建它。

另外,下面是编辑文件夹名后conf文件中的代码。让我知道,如果在这个也需要任何变化。

# Instruct Shiny Server to run applications as the user "shiny"
run_as shiny;

# Specify the authentication method to be used.
# Initially, a flat-file database stored at the path below.
auth_passwd_file /etc/shiny-server/nashboard/passwd;

# Define a server that listens on port 3838
server {
  listen 3838;

  # Define a location at the base URL
  location /nashboard {

    # Only up tp 20 connections per Shiny process and at most 3 Shiny processes
    # per application. Proactively spawn a new process when our processes reach
    # 90% capacity.
    utilization_scheduler 20 .9 3;

    # Host the directory of Shiny Apps stored in this directory
    site_dir /srv/shiny-server/nashboard;

    # Log all Shiny output to files in this directory
    log_dir /var/log/shiny-server;

    # When a user visits the base URL rather than a particular application,
    # an index of the applications available in this directory will be shown.
    directory_index on;
    app_init_timeout 250 ;
  }
}

# Provide the admin interface on port 4151
admin 4151 {

  # Restrict the admin interface to the usernames listed here. Currently
  # just one user named "admin"
  required_user admin;
}
