opencv - brew 链接 jpeg 问题

Question

我正在尝试在 Mac OSX Lion 上安装 opencv。

brew 安装 opencv

我收到以下错误(以及其他一些类似的错误)

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

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

我不明白这是什么意思？我应该做什么？谢谢

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

要brew link jpeg成功:

1. 删除(并备份)上述任何文件
2. 再次启动 brew link jpeg。
