Question

我需要在我的项目中使用OpenCV 2.4.4版本，但出于某种原因我无法使用自制软件安装它。

当我运行自制程序版本opencv时，我得到：

/usr/local$ brew versions opencv
2.4.5    git checkout ae74fe9 /usr/local/Library/Taps/homebrew-science/opencv.rb
2.4.4a   git checkout 3efa797 /usr/local/Library/Taps/homebrew-science/opencv.rb
2.4.4    git checkout d85d011 /usr/local/Library/Taps/homebrew-science/opencv.rb
2.4.3    git checkout 8cb3f45 /usr/local/Library/Taps/homebrew-science/opencv.rb
2.4.2    git checkout b64b319 /usr/local/Library/Taps/homebrew-science/opencv.rb
2.4.1    git checkout 3d32cf1 /usr/local/Library/Taps/homebrew-science/opencv.rb
2.4.0    git checkout 2a8c46b /usr/local/Library/Taps/homebrew-science/opencv.rb
2.3.1a   git checkout cdaf83d /usr/local/Library/Taps/homebrew-science/opencv.rb
2.2      git checkout 032047f /usr/local/Library/Taps/homebrew-science/opencv.rb
2.1.1-pre git checkout 2438f42 /usr/local/Library/Taps/homebrew-science/opencv.rb
HEAD     git checkout c658897 /usr/local/Library/Taps/homebrew-science/opencv.rb
2.1.0    git checkout ecb6a3e /usr/local/Library/Taps/homebrew-science/opencv.rb
/usr/local$  git checkout d85d011 /usr/local/Library/Taps/homebrew-science/opencv.rb

但是当我跑步时：

git checkout d85d011 /usr/local/Library/Taps/homebrew-science/opencv.rb

我明白了：

error: pathspec 'd85d011' did not match any file(s) known to git.
error: pathspec 'Library/Taps/homebrew-science/opencv.rb' did not match any file(s) known to git.

Answer 1

我也遇到了这个问题。要切换到特定分支（2.4.4或2.4.3），您必须导航到正确的git文件夹。在这种情况下，你想去homebrew-science子文件夹。

cd /usr/local/Library/Taps/homebrew-science
git checkout d85d011 opencv.rb结帐分行2.4.4
brew install opencv（如果您已经安装了其他版本，则可能需要运行brew unlink opencv）

Answer 2

如果有人想通过自制软件安装其他版本的opencv，你可以通过https://github.com/Homebrew/homebrew-science/commits/master/opencv.rb找到合适的opencv.rb版本

0fb1904适用于2.4.11_2

如果git checkout对您不起作用，您也可以手动复制文件内容。（备份现有的opencv.rb是安全的）

使用HomeBrew安装旧版本的OpenCv 2.4.4
