Question

我正在尝试在Mac OSX Lion上安装opencv。

brew install opencv

我收到以下错误（以及其他一些类似错误）

Error: The linking step did not complete successfully
The formula built, but is not symlinked into /usr/local
You can try again using `brew link jpeg'

当我这样做时

brew link jpeg
Linking /usr/local/Cellar/jpeg/8d... ln: wrjpgcom: File exists

我不明白这意味着什么？我该怎么办？感谢

Answer 1

检查/usr/local文件夹中的以下文件：

bin/cjpeg
bin/djpeg
bin/jpegtran
bin/rdjpgcom
bin/wrjpgcom
include/jconfig.h
include/jerror.h
include/jmorecfg.h
include/jpeglib.h
lib/libjpeg.8.dylib
lib/libjpeg.a
share/man/man1/cjpeg.1
share/man/man1/djpeg.1
share/man/man1/jpegtran.1
share/man/man1/rdjpgcom.1
share/man/man1/wrjpgcom.1

让brew link jpeg成功：

删除（并备份）上述任何文件
再次启动brew link jpeg。

Answer 2

在酒窖外找到文件wrjpgcom并删除它。

问题是Homebrew正在尝试将该文件符号链接到/ usr / local，但符号链接的目标已作为另一个文件存在。
