为什么在conda-build的build过程中$CONDA_PREFIX设置为$BUILD_PREFIX？

如何解决为什么在conda-build的build过程中$CONDA_PREFIX设置为$BUILD_PREFIX？

我有以下 build.sh 并且想通过简单地将 $RECIPE_DIR 复制到 $CONDA_PREFIX/... 来安装我的 python 包

#!/bin/sh

# Variables
# package_name="filip_test_package"
dir_in_conda=$CONDA_PREFIX/lib/python3.8/site-packages/$PKG_NAME

# Install
echo "Installing"
echo $CONDA_PREFIX
echo $RECIPE_DIR
echo $PKG_NAME

mkdir $dir_in_conda
cp -RT $RECIPE_DIR/$PKG_NAME $dir_in_conda

但是，在执行期间，我得到了以下堆栈跟踪。似乎 $CONDA_PREFIX 被替换为 $BUILD_PREFIX 但我不知道为什么。我需要在我的 Meta.yaml 中设置一些东西吗？
