使用kerl 管理 erlang 版本

      以前 用kerl  在这一步  kerl build R16B03 r16b03  总报错 

  configure: error: No curses library functions found

  configure: error: /bin/bash '/home/bryanhunter/.kerl/builds/r14b04/otp_src_R14B04/erts/configure' failed for erts

上网google 后说装 I did a "sudo apt-get update" and tried to build with kerl again and it failed in the same way. I then did a "sudo apt-get -y install libncurses5-dev". I tried again after that, and everything builds successfully.

安装后要激活 

. /path/to/install/dir/activate

如何要切换版本

  source 

/path/to/install/dir/activate
