我實際上所做的是,第3步和第4步在上面輸出了相同的錯誤。
1.Downloaded ImageMagick-7.0.5-4-Q16-x64-dll
2.Set my Path to C:\Program Files (x86)\ImageMagick-7.0.5-Q16\include
set
3.Install the gem using this command:
gem install rmagick --platform=ruby -- --with-opt-lib=C:\ImageMagick-7.0.5-Q16\lib --with-opt-include=C:\ImageMagick-7.0.5-Q16\include
4. or gem install rmagick
5. Using Windows 10 machine
RMagick
似乎還不支持ImageMagick 7。 嘗試使用最新版本的ImageMagick 6.9安裝rmagick。
好的,我已設法安裝它。
請遵循本指南。
步驟1:下載並安裝
ImageMagick-6.9.8-3-Q16-HDRI-x64-dl
步驟2:設置並創建一個名為CLASSPATH的新環境變量,並將其值設置為
.;C:\ImageMagick-6.9.8-Q16-HDRI\include;lib C:\ImageMagick-6.9.8-Q16-HDRI\lib
步驟3:安裝gem
gem install rmagick --platform=ruby -- --with-opt-lib=C:\ImageMagick-6.9.8-Q16-HDRI\lib --with-opt-include=C:\ImageMagick-6.9.8-Q16-HDRI\include
重要提示!!!
當您下載並安裝ImageMagick時,請確保在設置路徑和gem安裝時准確鍵入版本號。
完全遵循ImageMagic-6.9.8-3-Q16-HDRI之類的示例。
