错误:运行终端时，必须将CONDA_BUILD_SYSROOT或sdkroot.设置为交叉编译

Question

所以我的问题是，当我在MacBook专业版M1上运行终端时，在安装了miniforge3和Conda之后，每当我运行终端时，首先出现的事情是：

Last login: Thu Jul  1 15:36:59 on ttys000
ERROR: CONDA_BUILD_SYSROOT or SDKROOT has to be set for cross-compiling
activate_clang:67: read-only file system: /meson_cross_file.txt
activate_clang:68: read-only file system: /meson_cross_file.txt
activate_clang:69: read-only file system: /meson_cross_file.txt
activate_clang:70: read-only file system: /meson_cross_file.txt
activate_clang:71: read-only file system: /meson_cross_file.txt

在谷歌上搜索这个错误没有任何帮助，或者我只是得到了“没有结果”的消息。我该如何正确地设置它呢？

Answer 1

在执行以下操作时，我遇到了与miniforge，Apple Silicon (M1)相同的场景：

# Exclude external factors in my environment
$> mv ~/.zshrc ~/.not_zshrc
<close/open terminal>

$> curl -L -O https://github.com/conda-forge/miniforge/releases/latest/download/Miniforge3-MacOSX-arm64.sh
$> sh Miniforge3-MacOSX-arm64.sh -b -p ~/miniforge3
$> export PATH=~/miniforge3/bin:$PATH
$> conda init zsh
<close/open terminal>

$> conda create -n test clang_osx-64
$> conda activate test

所涉及的激活脚本是这样构建的：

if [ "@CONDA_BUILD_CROSS_COMPILATION@" = "1" ]; then
  _CMAKE_ARGS="${_CMAKE_ARGS} -DCMAKE_SYSTEM_NAME=Darwin -DCMAKE_SYSTEM_PROCESSOR=@UNAME_MACHINE@ -DCMAKE_SYSTEM_VERSION=@UNAME_KERNEL_RELEASE@"
  _MESON_ARGS="${_MESON_ARGS} --cross-file $BUILD_PREFIX/meson_cross_file.txt"
  echo "[host_machine]" > $BUILD_PREFIX/meson_cross_file.txt
  echo "system = 'darwin'" >> $BUILD_PREFIX/meson_cross_file.txt
  echo "cpu = '@UNAME_MACHINE@'" >> $BUILD_PREFIX/meson_cross_file.txt
  echo "cpu_family = '@MESON_CPU_FAMILY@'" >> $BUILD_PREFIX/meson_cross_file.txt
  echo "endian = 'little'" >> $BUILD_PREFIX/meson_cross_file.txt
fi

我相信这是因为Conda-Forge的资源持续集成无法访问Apple Silicon，因为他们构建了我们都在使用的可爱的二进制文件(他们使用英特尔/AMD拱门来构建Arm64；即交叉编译)。然后将其设置并传播到实际使用所述硬件的那些设备。

不幸的是，这将创建一个始终正确的激活：

if [ "1" = "1" ]; then
  _CMAKE_ARGS="${_CMAKE_ARGS} -DCMAKE_SYSTEM_NAME=Darwin -DCMAKE_SYSTEM_PROCESSOR=x86_64 -DCMAKE_SYSTEM_VERSION=13.4.0"
  _MESON_ARGS="${_MESON_ARGS} --cross-file $BUILD_PREFIX/meson_cross_file.txt"
  echo "[host_machine]" > $BUILD_PREFIX/meson_cross_file.txt
  echo "system = 'darwin'" >> $BUILD_PREFIX/meson_cross_file.txt
  echo "cpu = 'x86_64'" >> $BUILD_PREFIX/meson_cross_file.txt
  echo "cpu_family = 'x86_64'" >> $BUILD_PREFIX/meson_cross_file.txt
  echo "endian = 'little'" >> $BUILD_PREFIX/meson_cross_file.txt
fi

虽然不是修复，但您可以在激活事件之前将BUILD_PREFIX设置为某个可写区域：

BUILD_PREFIX="/some/writable/dir"
conda activate test

但是，我宁愿忽略这条消息。BUILD_PREFIX实际上只在conda build操作期间使用(据我所知)。
