【Android】使用Appium+python控制真机,碰到的问题以及处理(持续更新)

问题:
selenium.common.exceptions.WebDriverException: Message: A new session could not be created. 
(Original error: Command failed: C:\Windows\system32\cmd.exe /s /c "D:\android-sdk-windows\platform-tools\adb.exe -s 91f7e690 install
"C:\Program Files (x86)\Appium\node_modules\appium\build\settings_apk\settings_apk-debug.apk"" Failed to install C:\Program Files (x86)\Appium\node_modules\appium\build\settings_apk\settings_apk-debug.apk:
Failure [INSTALL_FAILED_ALREADY_EXISTS: Attempt to re-
install io.appium.settings without first uninstalling.] 解决: C:\Program Files (x86)\Appium\node_modules\appium\lib\devices\android 找到Android.js 文件,注释下述的三行代码即可:(颜色为红色的代码行)

 

 

 

报错:
command failed shell "ps 'uiautomator'"

解决:

1、找到appium的安装目录下的adb.js文件,目录为:

Appium\node_modules\appium\node_modules\appium-adb\lib 

2、打开adb.js,找到如下代码:

ADB.prototype.shell
= function (cmd, cb) { if (cmd.indexOf('"') === -1) { cmd = '"' + cmd + '"'; } var execCmd = 'shell ' + cmd; this.exec(execCmd, cb); };
在这段代码下面加入这段代码: ADB.prototype.shell_grep
= function (cmd, grep, cb) { if (cmd.indexOf('"') === -1) { cmd = '"' + cmd + '"'; } var execCmd = 'shell ' + cmd + '| grep ' + grep; this.exec(execCmd, cb); };
再找到如下代码进行注释掉:
ADB.prototype.getPIDsByName
= function (name, cb) { logger.debug("Getting all processes with '" + name + "'"); this.shell("ps '" + name + "'", function (err, stdout) { if (err) return cb(err); stdout = stdout.trim(); var procs = []; var outlines = stdout.split("\n"); outlines.shift(); _.each(outlines, function (outline) { if (outline.indexOf(name) !== -1) { procs.push(outline); } }); if (procs.length < 1) { logger.debug("No matching processes found"); return cb(null, []); } var pids = []; _.each(procs, function (proc) { var match = /[^\t ]+[\t ]+([0-9]+)/.exec(proc); if (match) { pids.push(parseInt(match[1], 10)); } }); if (pids.length !== procs.length) { var msg = "Could not extract PIDs from ps output. PIDS: " + JSON.stringify(pids) + ", Procs: " + JSON.stringify(procs); return cb(new Error(msg)); } cb(null, pids); }); }; 把这段代码注释掉,用如下代码代替:
ADB.prototype.getPIDsByName
= function (name, cb) { logger.debug("Getting all processes with '" + name + "'"); this.shell_grep("ps", name, function (err, stdout) { if (err) { logger.debug("No matching processes found"); return cb(null, []); } var pids = []; _.each(procs, function (proc) { var match = /[^\t ]+[\t ]+([0-9]+)/.exec(proc); if (match) { pids.push(parseInt(match[1], 10)); } }); if (pids.length !== procs.length) { var msg = "Could not extract PIDs from ps output. PIDS: " + JSON.stringify(pids) + ", Procs: " + JSON.stringify(procs); return cb(new Error(msg)); } cb(null, pids); }); }; 3 :重启软件
