从函数运行 adb 时出现“找不到命令”，但不是以其他方式运行

Question

在我的 ~/.zshrc 文件中找到了函数，它打印 command not found: adb

install_apk_on_device() {
  set -x
  local device=${1}
  local path=${2}

  if [[ -z "${device}" ]]; then
    echo "The device is empty"
  elif [[ -z "${path}" ]]; then 
    echo "The path is empty"
  else 
    adb -s "$device" install -r "$path"
  fi
}

output: 

+install_apk_on_device:3> local device=emulator-5554
+install_apk_on_device:4> local path=MY_APK_PATH
+install_apk_on_device:6> [[ -z emulator-5554 ]]
+install_apk_on_device:8> [[ -z MY_APK_PATH ]]
+install_apk_on_device:11> adb -s emulator-5554 install -r MY_APK_PATH
install_apk_on_device:11: command not found: adb

但是，如果您使用相同的参数直接运行此 adb 命令，例如 adb -s 52036d8b50671495 install -r .//androidApp/build/outputs/apk/debug/androidApp-debug.apk，则会安装 apk

另外，如果我将 adb 命令从 else-branch 中取出到函数的请求处，它会按预期工作

install_apk_on_device() {
  adb -s "$1" install -r "$2"
  local device=${1}
  local path=${2}

  if [[ -z "${device}" ]]; then
    echo "The device is empty"
  elif [[ -z "${path}" ]]; then 
    echo "The path is empty"
  fi
}

这些是我的路径：

PATH=/bin:/usr/bin:/usr/local/bin:${PATH}
export PATH
export HOME=/Users/ruanvd5
export JAVA_HOME=$HOME/Library/Java/JavaVirtualMachines/corretto-1.8.0_275/Contents/Home
export ANDROID_HOME=$HOME/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools
export PATH=$PATH:$HOME/Programming/elixirSourceCode/elixir/bin
export GRADLE_USER_HOME=$HOME/.gradle

另外，这是我的declare -p PATH

export -T PATH path=( 
/bin /usr/bin /usr/local/bin /usr/local/bin /usr/bin /bin /usr/sbin /sbin /usr/local/munki /Library/Apple/usr/bin 
/Users/ruanvd5/Library/Android/sdk/emulator 
/Users/ruanvd5/Library/Android/sdk/tools 
/Users/ruanvd5/Library/Android/sdk/tools/bin 
/Users/ruanvd5/Library/Android/sdk/platform-tools 
/Users/ruanvd5/Programming/elixirSourceCode/elixir/bin 
)

混淆了我写错了:-)

Answer 1

不同于 bash（和其他符合 POSIX 的 shell；这是 zsh 违反规范的地方，就像 the standard specifies 那样，只有命名空间中的全大写名称用于环境变量 - 也是 em> 用于常规 shell 变量的命名空间 -- 应该对 POSIX 指定的工具有意义），名称 path 即使是小写字母也对 zsh 有意义。更改您的变量名称。

也就是说，不是local path=${2}（在zsh中，它会更改活动的PATH作为副作用），而是改为local apk_path=$2。

install_apk_on_device() {
  local device apk_path
  device=$1; apk_path=$2

  [[ -z $device ]] && { echo "The device is empty" >&2; return 1; }
  [[ -z $apk_path ]] && { echo "The path is empty" >&2; return 1; }

  adb -s "$device" install -r "$apk_path"
}

尝试引用作业

  local device="${1}"
  local path="${2}"
