Question

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

确实没有文件：

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

Answer 1

让我们看看openblas的已安装版本是否为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

要解决此问题，我们可以从已安装的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

有效！

R

R version 3.5.0 (2018-04-23) -- "Joy in Playing"
Copyright (C) 2018 The R Foundation for Statistical Computing
Platform: x86_64-apple-darwin17.4.0 (64-bit)

Answer 2

另一种解决方案是重新安装R：

brew reinstall r

这将重新链接R与正确的库，并且您将没有任何符号链接，这些符号链接可能会变得孤立或稍后导致问题。这不会影响您已经安装的任何R软件包。另外，如果您已经安装了带有Brew的R的最新版本，并且瓶子仍在计算机上，则无需再次下载瓶子。

Answer 3

brew upgrade R在大多数情况下将确保已安装要求：

==> Upgrading 1 outdated package:
r 3.5.3 -> 3.6.1
==> Upgrading r
==> Pouring r-3.6.1.mojave.bottle.tar.gz
?  /usr/local/Cellar/r/3.6.1: 2,121 files, 56.6MB
Removing: /usr/local/Cellar/r/3.5.3... (2,118 files, 55.8MB)

Answer 4

就我而言，运行 uninstall 和 reinstall 并没有解决问题。运行 brew doctor 后发现我有无衬里的小桶，包括 gcc 运行 brew link gcc 解决了这个问题。

Answer 5

我有一个类似的错误，首先是在Mac OSX 10.14上使用R 3.5.2_2的“ libopenblas”，然后是“ libgfortran”。

通过解决此问题：

brew upgrade R

R在此之后可以完美工作：
