作者是ubuntu系统，在安装scRNAtoolVis的R包时出现问题，
devtools::install_github('junjunlab/scRNAtoolVis')
报错：
** package ‘magick’ successfully unpacked and MD5 sums checked
** using staged installation
Package Magick++ was not found in the pkg-config search path.
Perhaps you should add the directory containing `Magick++.pc'
to the PKG_CONFIG_PATH environment variable
No package 'Magick++' found
Using PKG_CFLAGS=
Using PKG_LIBS=-lMagick++-6.Q16
--------------------------- [ANTICONF] --------------------------------
Configuration failed to find the Magick++ library. Try installing:
- deb: libmagick++-dev (Debian, Ubuntu)
- rpm: ImageMagick-c++-devel (Fedora, CentOS, RHEL)
- csw: imagemagick_dev (Solaris)
- brew imagemagick@6 (MacOS)
If Magick++ is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a Magick++.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'
-------------------------- [ERROR MESSAGE] ---------------------------
<stdin>:1:10: fatal error: Magick++.h: No such file or directory
compilation terminated.
--------------------------------------------------------------------
ERROR: configuration failed for package ‘magick’
* removing ‘/mnt/data/lib/R/magick’
原因就是缺少libmagick库。
解决方案：
sudo apt-get install libmagick++-dev
wget https://cloud.r-project.org/src/contrib/magick_2.8.2.tar.gz --no-check-certificate
R CMD INSTALL magick_2.8.2.tar.gz
再进入R里面，devtools::install_github('junjunlab/scRNAtoolVis')
