ruby - 在 Ubuntu 上安装 proj4rb : Cannot find proj_api. h header

Question

正在尝试安装proj4rb在 Ubuntu 或 Linux Mint 上失败并出现以下错误:

Building native extensions.  This could take a while...
ERROR:  Error installing proj4rb:
    ERROR: Failed to build gem native extension.

./siteconf20161110-4168-1b7och9.rb extconf.rb
checking for proj_api.h... no
extconf.rb:6:in `<main>': Cannot find proj_api.h header (RuntimeError)

不清楚需要哪些包，而且我在 stackoverflow 上找不到任何相关帖子。

Answer 1

只需安装 libproj-dev封装:

sudo aptitude install libproj-dev
gem install proj4rb
