TeamCity：PhantomJS 在 60000 毫秒内没有捕获，正在杀死

Question

我在 CI 环境中运行测试时遇到问题。该配置在 MacOS 10.11.6 (El Capitan) 上运行良好，使用 Node v6.0.0 / npm 3.8.6，但在使用 Node v4.2.2 / npm 2.14.7 运行 Windows 的 TeamCity 9.1.6 代理上，它惨遭失败PhantomJS have not captured in 60000 ms 的错误。

这是 TeamCity 上的示例堆栈跟踪：

Answer 1

问题解决了！在我们的 CI 环境中，我们不是通过运行 npm install 来获取节点模块 - 我们是在本地压缩 node_modules 目录并将其添加到我们的源代码中。

在 Mac 上压缩它并在 Windows 上分解它并尝试使用这些模块，尤其是 phantomjs-prebuilt，是它没有捕获的原因。

我把它从 Windows 上压缩了，它运行良好。

Answer 2

我在本地遇到过 PhantomJS have not captured in 60000 ms, killing 问题，经过一些实验发现它可能是由以下原因引起的：

1. 类路径中可用的 PhantomJS 与 phatomjs-prebuilt 下载到项目的 node_modules。我刚刚删除了全局可用的。
2. 缺少PHANTOMJS_CDNURL 环境（系统）变量，指向一个maven 存储库，检查where to get PhantomJS。
