我正在尝试opencv在 Mac OSX Lion上安装。
brew install 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？我该怎么办？谢谢
