passenger-nginx-module找不到`curl-config`命令

Question

任何人都可以帮助我：

rvmsudo passenger-install-nginx-module

现在它显示了这个：     检查所需的软件......

 * Checking for Curl development headers with SSL support...
      Found: no
      Error: Cannot find the `curl-config` command.
Installation instructions for required software

 * To install Curl development headers with SSL support:
   Please run apt-get install libcurl4-openssl-dev or libcurl4-gnutls-dev, whichever you prefer.

现在我正在尝试安装

sudo apt-get install libcurl4-openssl-dev

主要问题：
