dyld：庫未加載：/usr/local/opt/openblas/lib/libopenblasp-r0.2.20.dylib

Question

當我運行R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

確實該文件不存在：

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 上使用自制軟件安裝 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

看看openblas安裝的版本是openblas 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

我們有 0.3.0 但 R 正在尋找 0.2.20

為了解決這個問題，我們可以從安裝的 dylib 創建一個符號鏈接：

ln -s /usr/local/opt/openblas/lib/libopenblas.dylib \
      /usr/local/opt/openblas/lib/libopenblasp-r0.2.20.dylib

有用！

R

R version 3.5.0 (2018-04-23) -- "Joy in Playing"

Platform: x86_64-apple-darwin17.4.0 (64-bit)

Answer 2

另一種解決方案是簡單地重新安裝 R：

brew reinstall r

這將根據正確的庫重新鏈接 R，並且您不會有任何可能成為孤立的或稍后導致問題的符號鏈接。 這不會影響您已經安裝的任何 R 包。 此外，如果您已經使用 brew 安裝了最新版本的 R 並且瓶子仍在您的計算機上，那么您將不必再次下載瓶子。

Answer 3

在我的情況下，運行uninstall並reinstall並沒有解決問題。 運行brew doctor發現我有單衣小桶，包括gcc運行brew link gcc固定的問題。

Answer 4

在大多數情況下brew upgrade R將確保安裝了要求：

==> Upgrading 1 outdated package: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 5

我有一個類似的錯誤，首先是“libopenblas”，然后是 Mac OSX 10.14 上使用 R 3.5.2_2 的“libgfortran”。

通過執行以下操作解決了它：

brew upgrade R

Updating Homebrew...
==> Auto-updated Homebrew!
Updated 2 taps (homebrew/cask and homebrew/bundle).
No changes to formulae.

==> Upgrading 1 outdated package:
r 3.5.2_2 -> 3.6.1

R 在此之后完美運行：
