我试图在 linux mint 中安装 opencv。我在 opencv 文件夹中运行 cmake 命令。
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
但是我在发布文件夹中运行 make 命令时遇到了一些与 pango 相关的错误:
//usr/lib/x86_64-linux-gnu/libgtk-3.so.0: undefined reference to `pango_attr_font_features_new'
//usr/lib/x86_64-linux-gnu/libgtk-3.so.0: undefined reference to `pango_renderer_set_alpha'

最佳答案
你需要使用 $ mkvirtualenv cv -p python2 启动虚拟环境
