node.js - Protractor 错误，意外 token )

Question

我正要开始学习 Protractor 并按照那里的简单教程 http://www.protractortest.org/#/tutorial

但不幸的是，运行此命令后出现奇怪的错误 protractor conf.js

[launcher] Process exited with error code 1
   /usr/local/lib/node_modules/protractor/node_modules/q/q.js:126
       throw e;

Node 版本:v0.10.37

java 版本:1.8.0_66

Protractor :版本 3.0.0

jadmine : jasmine v2.3.2 jasmine-core v2.3.4

更新

已克隆存储库 https://github.com/angular/protractor

运行以下命令

./bin/webdriver-manager update --standalone

./bin/webdriver-manager start

打开新的终端标签

更改为网站目录

使用 npm start 运行网站文件夹，并且该网站已经在端口 8080 上运行

打开新的终端选项卡，仍在网站文件夹下

运行测试命令 npm test 然后 chrome 浏览器会在几秒钟内打开并在上面显示相同的错误

Protractor 升级到 WebDriver 2.48.2 并发布了版本 3.0.0。此版本的 WebDriver 与 Node.js 版本 <4 不兼容。

来自 Protractor 项目中的 CHANGELOG.md:

(18e1f71) chore(webdriver): upgrade Protractor to webdriver 2.48.2

BREAKING CHANGE:
1) Users will no longer be able to use node versions < 4.
2) There are significant changes to the control flow, and tests may need to be modified to be compliant with the new control flow. See Changes

将 Protractor 降级到 2.5.1 或将 Node.js 升级到 >= v4.0.0 应该可以解决您的问题。见 here有关 Protractor v3.0.0 中重大更改的更多信息。
