为 microsamba 设置 direnv

Question

今天我花了几个小时为“microsamba”设置 direnv。

由于安装减少，没有

acticate

脚本可供源，我在设置正确的布局时遇到了麻烦。

比如说

layout_micromamba() {
  export MAMBA_HOME="${HOME}/Data/micromamba"
  export MAMBA_EXE="${HOME}/.local/bin/micromamba"
  export MAMBA_ROOT_PREFIX='/home/abu/Data/micromamba'
  local my_shell=$(basename ${SHELL})
  local env_name="$1"
  __mamba_setup="$("${MAMBA_EXE}" shell hook --shell "${my_shell}" --root-prefix "${MAMBA_ROOT_PREFIX}" 2> /dev/null)"
  __mamba_activate="$("${MAMBA_EXE}" activate "${env_name}")"

  eval " ${__mamba_setup}"

  if [ -n "$1" ]; then
    # Explicit environment name from layout command.
    eval activate ${env_name}

  elif (grep -q name: environment.yml); then
    # Detect environment name from `environment.yml` file in `.envrc` directory
    eval "$mamba_hook; micromamba activate $(grep name: environment.yml | sed -e 's/name: //')"

  else
    (>&2 echo No environment specified);
    exit 1;

  fi;

  unset __mamba_setup
  unset __mamba_activate
}

输出错误

direnv: loading ~/test-env/.envrc
action: hool not in {init,deinit,reinit,hook,activate,deactivate,reactivate}
Run with --help for more information.

'micromamba' is running as a subprocess and can't modify the parent shell.
Thus you must initialize your shell before using activate and deactivate.

    To initialize the current bash shell, run:
        $ eval "$(micromamba shell hook --shell=bash)"
    and then activate or deactivate with:
        $ micromamba activate
    
To automatically initialize all future (bash) shells, run:
    $ micromamba shell init --shell=bash --prefix=~/micromamba

Supported shells are {bash, zsh, csh, xonsh, cmd.exe, powershell, fish}.

critical libmamba Shell not initialized
direnv: export ~PATH

我尝试了多种方法，但没有成功。

几个小时后我找到了解决方案。

microsamba activate

必须与 shell 函数

microsamba

相关，该函数在调用

micromamba shell hook

命令后生成。由于我在网上找不到解决方案，我想分享

direnv

的正确布局。将此代码放入您的

~/.config/direnv/direnvrc

文件中：

#
# micromamba
#
# touch a '.envrc' file in your project directory and insert the following code in it:
# layout micromamba <your-environment-name>

layout_micromamba() {
  # adjust the target to your installation of the BINARY micromamba
  export MAMBA_EXE="${HOME}/.local/bin/micromamba"
  # adjust the target to the installation prefix
  export MAMBA_ROOT_PREFIX="${HOME}/micromamba"
  # find the shell in use
  local my_shell=$(basename ${SHELL})
  local env_name="$1"
  __mamba_setup="$("${MAMBA_EXE}" shell hook --shell "${my_shell}" --root-prefix "${MAMBA_ROOT_PREFIX}" 2> /dev/null)"

  eval " ${__mamba_setup}"

  if [ -n "$1" ]; then
    # Explicit environment name from layout command
    # DO NOT USE $MAMBA_EXE , instead the shell function 'micromamba' which got generated after '__mamba_setup'.
    micromamba activate ${env_name}

  elif (grep -q name: environment.yml); then
    # Detect environment name from `environment.yml` file in `.envrc` directory
    micromamba activate $(grep name: environment.yml | sed -e 's/name: //')

  else
    (>&2 echo No environment specified);
    exit 1;

  fi;

  unset __mamba_setup

}
