Conda gcc 不会取代系统 gcc

Question

我正在尝试在 Conda 环境中编译一些代码，我之前在其中安装了编译器包gcc_linux-64。

但是，即使在停用并再次重新激活环境之后， gcc仍然是/usr/bin/gcc.

我该怎么做才能让 Conda 按预期工作，即。使用我安装的工具？就像其他软件一样git。

任何帮助将不胜感激，提前致谢！

如果你这样做：

export CONDA_BUILD=1
conda activate <name-of-env-in-which-gcc_linux-64-is-installed>

你会看见：

在您的 make 文件中，您可以使用类似的变量$CC。
