/system/bin/sh: screenrecord: inaccessible or not found 報錯解決方案

在我們平時測試工作中，可能需要對 Android 手機進行錄屏，第一時間我們肯定想到強大的 adb 命令。但是當我們用 adb 錄製的時候，往往會報錯 screenrecord: inaccessible or not found

~ $ adb shell screenrecord /sdcard/test.mp4
/system/bin/sh: screenrecord: inaccessible or not found

這是因為現在很多手機為了安全把 screenrecord 功能給回收了，導致我們無法再用該命令列進行錄屏操作。
透過adb shell ls /system/bin/命令可以看到ls: /system/bin//screenrecord: Permission denied，說明確實沒有錄屏許可權了。

那麼，如果想要錄屏怎麼辦？這裡推薦一個工具，那就是 scrcpy

安裝 (僅 macOS)：

brew install scrcpy

如果你沒有 adb，則需要先安裝：

brew cask install android-platform-tools

執行 scrcpy

安裝完畢後，電腦連線手機，執行 scrcpy 可在電腦上面看到手機實時投屏：

scrcpy

錄屏

如果想要錄屏，執行以下兩個命令之一：

scrcpy --record test.mp4
scrcpy -r test.mp4

你也可以在不開啟實時映象顯示的情況錄屏：

scrcpy --no-display --record file.mp4
scrcpy -Nr file.mkv
