**appium目前最新的windows版本是1.4.16，在真机上测试程序时会报错：**

selenium.common.exceptions.SessionNotCreatedException: Message: A new 
    session could not be created. (Original error: Command failed: 
    C:\Windows\system32\cmd.exe /s /c "D:\Solf\android\platform-tools\adb.exe -s 
    16fcb2be shell "ps 'uiautomator'""
    ps: uiautomator
    )

##### 解决方法如下: #####

**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：**

**在这段代码下面加入这行代码：**

outlines.shift();

**3、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  
**4、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**：

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);
      });
    };

**5、重启appium**
