Rails使用paperclip报CommandNotFoundError错的解决

已安装ImageMagick,但在设定了指定大小后paperclip报错:

Paperclip::Errors::CommandNotFoundError (Could not run the `identify` command. Please install ImageMagick.):Command :: identify -format '%wx%h,%[exif:orientation]' '/var/folders/z2/n3vz292s0z7f995w0_bphm780000gn/T/1ce67fe3a364b6e5918d8fa96478ceef20170222-20952-1cruqw2.png[0]' 2>/dev/null

提示要你安装ImageMagick,但是前面说过已经装过了!!!

使用如下命令查看ImageMagick的信息:

brew info ImageMagick@6ImageMagick@6: stable 6.9.7-9 (bottled) [keg-only]Tools and libraries to manipulate images in many formatshttps://www.imagemagick.org//usr/local/Cellar/ImageMagick@6/6.9.7-9 (1,465 files, 22.2M)  Poured from bottle on 2017-02-22 at 18:05:21From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/[e-mail]==> DependenciesBuild: pkg-config ✔Required: libtool ✔, xz ✔Recommended: jpeg ✔, libpng ✔, libtiff ✔, freetype ✔Optional: fontconfig ✘, little-cms ✘, little-cms2 ✘, libwmf ✘, librsvg ✘, liblqr ✘, openexr ✘, ghostscript ✘, webp ✘, openjpeg ✘, fftw ✘, pango ✘==> RequirementsOptional: perl >= 5.5 ✔==> Options--with-fftw    Compile with FFTW support--with-fontconfig    Build with fontconfig support--with-ghostscript    Build with ghostscript support--with-hdri    Compile with HDRI support--with-liblqr    Build with liblqr support--with-librsvg    Build with librsvg support--with-libwmf    Build with libwmf support--with-little-cms    Build with little-cms support--with-little-cms2    Build with little-cms2 support--with-opencl    Compile with OpenCL support--with-openexr    Build with openexr support--with-openjpeg    Build with openjpeg support--with-openmp    Compile with OpenMP support--with-pango    Build with pango support--with-perl    Compile with PerlMagick--with-quantum-depth-16    Compile with a quantum depth of 16 bit--with-quantum-depth-32    Compile with a quantum depth of 32 bit--with-quantum-depth-8    Compile with a quantum depth of 8 bit--with-webp    Build with webp support--with-zero-configuration    Disables depending on XML configuration files--without-freetype    Build without freetype support--without-jpeg    Build without jpeg support--without-libpng    Build without libpng support--without-libtiff    Build without libtiff support--without-magick-plus-plus    disable build/install of Magick++--without-modules    Disable support for dynamically loadable modules--without-threads    Disable threads support==> CaveatsThis formula is keg-only, which means it was not symlinked into /usr/local.Older version of imagemagickIf you need to have this software first in your PATH run:  echo 'export PATH="/usr/local/opt/ImageMagick@6/bin:$PATH"' >> ~/.bash_profileFor compilers to find this software you may need to set:    LDFLAGS:  -L/usr/local/opt/ImageMagick@6/lib    CPPFLAGS: -I/usr/local/opt/ImageMagick@6/includeFor pkg-config to find this software you may need to set:    PKG_CONFIG_PATH: /usr/local/opt/ImageMagick@6/lib/pkgconfig

进入/usr/local/opt/ImageMagick@6/bin查看,命令都在,应该是没有加入到path中去:

echo 'export PATH="/usr/local/opt/ImageMagick@6/bin:$PATH"' >> ~/.bash_profile

现在ok了!
