量角器运行后出现 uncaughtException

问题描述

在升级到 Protractor 4.0.0 并因重大更改调整配置后，我们终于启动了测试.

After upgrading to Protractor 4.0.0 and adjusting the config because of the breaking changes, we finally have our tests launching.

现在，问题是在测试运行后它失败了:

Now, the problem is that after a test run it fails with:

[09:52:22] E/launcher - "process.on('uncaughtException'" error, see launcher
[09:52:22] E/launcher - Process exited with error code 199

如何调试此问题并了解其原因?

How to debug this problem and understand what is causing it?

尝试在疑难解答"模式下运行 Protractor:

Tried to run Protractor in "troubleshoot" mode:

$ protractor config/local.conf.js --troubleshoot

但得到完全相同的输出，但没有关于错误的详细信息.

but got exactly the same output with no details about the error.

推荐答案

这是目前正在修复应该是一个热修复很快.快速修复(在热修复发布之前)是更改 node_modules 中的代码或恢复到 3.3.0.

This is currently being fixed and there should be a hot fix out soon. The quick fix (before the hot fix is released) is to change the code in your node_modules or revert to 3.3.0.

编辑 node_modules/protractor/built/launcher.js 将第 168 行的 uncaughtException 替换为:

Edit node_modules/protractor/built/launcher.js replace the uncaughtException at line 168 with:

    process.on('uncaughtException', function (e) {
    var errorCode = exitCodes_1.ErrorHandler.parseError(e);
    if (errorCode) {
        var protractorError = e;
        exitCodes_1.ProtractorError.log(logger, errorCode, protractorError.message, protractorError.stack);
        process.exit(errorCode);
    }
    else {
        logger.error(e.message);
        logger.error(e.stack);
        process.exit(exitCodes_1.ProtractorError.CODE);
    }
});
