提问于 2018-06-01 08:59:31
当我运行R时，我得到：
dyld: Library not loaded: /usr/local/opt/openblas/lib/libopenblasp-r0.2.20.dylib
Referenced from: /usr/local/Cellar/r/3.5.0_1/lib/libR.dylib
Reason: image not found
Abort trap: 6实际上，这个文件是不存在的：
ls /usr/local/opt/openblas/lib/libopenblasp-r0.2.20.dylib
ls: cannot access '/usr/local/opt/openblas/lib/libopenblasp-r0.2.20.dylib': No such file or directory我在macOS 10.13.3上使用homebrew安装R，如下所示：
# Java
brew cask install java
# OpenBLAS (installs gcc and other dependencies)
brew install openblas
# R language for statistical computing
brew install r --with-openblas --with-java
# Install XQuartz, needed for R package "Cairo"
brew cask install xquartz
# Needed for R package "RMySQL"
brew install mariadb-connector-c
# Needed for R packages: udunits2, units, ggforce
brew install udunits回答 5

让我们看看安装的openblas版本是否为0.2.20：
brew info openblas
openblas: stable 0.3.0 (bottled), HEAD [keg-only]
Optimized BLAS library
https://www.openblas.net/
/usr/local/Cellar/openblas/0.3.0 (22 files, 139MB)
Poured from bottle on 2018-05-31 at 20:42:55
From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/openblas.rb
==> Dependencies
Required: gcc ✔
==> Options
--with-openmp
Enable parallel computations with OpenMP
--HEAD
Install HEAD version
==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local,
because macOS provides BLAS and LAPACK in the Accelerate framework.
For compilers to find this software you may need to set:
LDFLAGS: -L/usr/local/opt/openblas/lib
CPPFLAGS: -I/usr/local/opt/openblas/include
For pkg-config to find this software you may need to set:
PKG_CONFIG_PATH: /usr/local/opt/openblas/lib/pkgconfig我们有0.3.0，但R正在寻找0.2.20
为了解决这个问题，我们可以从安装的dylib创建一个符号链接：
ln -s /usr/local/opt/openblas/lib/libopenblas.dylib \
/usr/local/opt/openblas/lib/libopenblasp-r0.2.20.dylib它起作用了!

另一种解决方案是简单地重新安装R：
brew reinstall r这将针对正确的库重新链接R，并且您将不会有任何符号链接可能会变成孤立的或以后会导致问题。这不会影响你已经安装的任何R包。此外，如果您已经使用brew安装了最新版本的R，并且瓶子仍然在您的计算机上，那么您就不必再次下载瓶子了。

在我的例子中，运行uninstall和reinstall并没有解决这个问题。运行brew doctor时，我发现我有一些非内联的kegs，包括运行brew link gcc的gcc，解决了这个问题。
