以下是筆記:
一.修改Gemfile
|
1 2 |
gem 'rmagick', '2.13.2' |
二.安裝必要套件
|
1 |
sudo apt-get install imagemagick libmagickcore-dev |
然後bundle,這時會跑以下訊息
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 |

Make sure that `gem install rmagick -v '2.13.2'` succeeds before bundling. |
原因為找不到 MagickWand.h
這時再安裝以下
|
1 |
sudo apt-get install libmagickwand-dev |
然後再bundle一次應該就可以了
