gcc - 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，在那里我
之前安装的编译包gcc_linux-64 .

然而，即使在停用和重新激活环境之后，gcc还在/usr/bin/gcc .

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

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:

在你的 make 文件中，你可以使用像 $CC 这样的变量。反而。
