  • 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 ode_modulesappium ode_modulesappium-adblib
    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:

    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("
    ");
        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 = /[^	 ]+[	 ]+([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 = /[^	 ]+[	 ]+([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appium

    问题解决。
