我正在尝试在我的 Mac OS X 10.7.3 (Lion) 上安装Orange，并且在使用 pip 或从源代码构建时不断收到错误消息。首先，我收到一条错误消息：

error: command 'gcc-4.0' failed with exit status 1

我有 Xcode 4，它与 gcc 4.2.1 捆绑在一起。所以我安装了64-bit/32-bit Python 2.7.3，它内置了 gcc 4.2。我还尝试使用以下方法覆盖编译器选择：

export CC=gcc-4.2

但这产生了一个不同的错误：

gcc-4.2 not found, using clang instead
...
error: command 'clang' failed with exit status 1

这是完整的日志：

问题已解决：Xcode 4 实际上并没有附带 gcc-4.2；它带有新的 LLVM 编译器。

这只是一个问题：

export CC=llvm-gcc-4.2
export CXX=llvm-g++-4.2

然后建造橙色。

来自http://orange.biolab.si/forum/viewtopic.php?f=4&t=1568

export CC=gcc
export CXX=g++
pip install orange # for example

如果您不必了解版本号详细信息，似乎更可靠，对吧？（我以前没有做过这种事情，所以我不确定。）

更新：pip install orange示例（上面）当前安装的是旧版本的 Orange（版本 2.5a4 ）而不是 2.6。要获取开发版本，请使用：

pip install -e hg+https://bitbucket.org/biolab/orange#egg=Orange

我从这里得到了上面的命令。

我必须执行以下操作来修复 Mac OS Catalina 上的错误。您可以在命令行中运行它，也可以将其放入您的bash_profile.

export CC=gcc
export CXX=clang
