我的webpack构建开始失败，没有更新软件包。我假设一些次要版本更新导致了这一点，但无法弄清楚如何解决它。有谁知道该怎么办？

看起来您的@types/jasmine库已升级到最新版本，因为您有插入符号：
"@types/jasmine": "^2.2.34",
最新版本存在问题，bug建议。因此，请尝试在package.json中将版本设置为2.5.41：
"devDependencies": {
"@types/jasmine": "2.5.41"
}
也许您必须删除node-modules文件夹并运行npm install才能进行全新安装。

如果您没有使用Angular 2，请将您的TypeScript更新为2.1.6或更高版本。这应该会有所帮助。
根据this discussion，更正确的解决方案是将TypeScript更新为for (var i = 0; i < rawElems.length; i++) {
expanders[i] = new Expander(rawElems[i], false);
expanders[i].element.addaddEventListener("click", handleExpanderClick.bind(expanders[i]));
}
function handleExpanderClick(event) {
// `this` = the expander
// `this.element` = the element
// `event.currentTarget` = the element (also)
}
分支的最新稳定次要版本，截至目前为止2.x（2017年2月12日） 。构建日志中的错误表明您使用的是过时的2.1.6版本。最新的2.0.10定义文件在jasmine函数中进行了新的语法检查，该函数仅适用于TypeScript spyOn()。一般来说，你没有理由坚持>=2.1.0，所以请升级。但是，如果存在阻止升级的向后兼容性问题，则应在此处填写问题表单：https://github.com/Microsoft/TypeScript/issues并使编译器团队了解错误。
UPD ：避免使用2.0.10这样的行：package.json，"typescript": "2.0.10。而不是"typescript": "~2.0.0"您应该应用~限制（允许更新次要版本号，而不仅仅是修补程序），例如^。
希望有所帮助。很抱歉给您带来不便。

即使使用Angular 2+，我也遇到了这个问题。什么解决了我的问题，而不是降级Jasmine正在更新Typescript。
我的步骤是：
package.json更改为指向新版本的打字稿
"typescript": "~2.0.9" - ＆gt; "typescript": "^2.0.9" npm install
