command failed shell "ps 'uiautomator'"的解决
command failed shell "ps 'uiautomator'"的解决方式
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：
|
1

|
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：
|
1

|
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：

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：

3、重启appium
