appium1.4，运行自动化脚本时提示
org.openqa.selenium.SessionNotCreatedException: A new session could not be created. (Original error: Command failed: "D:\Program Files\android-sdk-windows\platform-tools\adb.exe" -s GSL0217302005195 shell "ps ‘uiautomator‘"
ps: uiautomator
解决办法：
找到appium的安装目录：D:\Program Files (x86)\Appium\node_modules\appium\node_modules\appium-adb\lib下，打开abd.js
1、找到这段代码：
ADB.prototype.shell = function (cmd, cb) {
if (cmd.indexOf(‘"‘) === -1) {
cmd = ‘"‘ + cmd + ‘"‘;
}
var execCmd = ‘shell ‘ + cmd;
this.exec(execCmd, cb);
};
在该代码下边加上：
//解决 ps uiautomator问题
ADB.prototype.shell_grep = function (cmd, grep, cb) {
if (cmd.indexOf(‘"‘) === -1) {
cmd = ‘"‘ + cmd + ‘"‘;
}
var execCmd = ‘shell ‘ + cmd + ‘| grep ‘ + grep;
this.exec(execCmd, cb);
};
2、找到第二段代码，注释掉该方法：
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");
_.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);
});
};
在注释掉的代码下边加上：
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、保存adb.js，重启appium，可以解决
使用appium1.4在android8.0真机上测试程序时报错command failed shell "ps 'uiautomator'"的解决方式
