ruby - 在Ubuntu上安装proj4rb:找不到proj_api.h header

尝试在Ubuntu或Linux Mint上安装proj4rb失败，并显示以下错误：

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)

目前尚不清楚需要哪些软件包，而且在stackoverflow上也找不到任何相关的文章。

最佳答案

只需安装libproj-dev软件包：

sudo aptitude install libproj-dev
gem install proj4rb

# Building native extensions.  This could take a while...
# Successfully installed proj4rb-1.0.0
