[at-loader] node_modules\@types\jasmine出错

Question

我的webpack版本开始莫名其妙地失败了，没有更新的包。我想可能是一些小的版本更新导致了这个问题，但是我不知道如何解决这个问题。有人知道该怎么做吗？

ERROR in [at-loader] node_modules\@types\jasmine\index.d.ts:39:52

Answer 1

看起来你的@types/jasmine库升级到了最新版本，因为你有插入符号：

"@types/jasmine": "^2.2.34",

正如此bug所显示的，最新版本存在问题。因此，现在可以在package.json中将版本设置为2.5.41：

"devDependencies": {
  "@types/jasmine": "2.5.41"
}

也许你必须删除你的node-modules文件夹并运行npm install来进行全新的安装。

如果您使用的不是Angular 2，请将您的TypeScript更新到2.1.6或更高版本。这应该会有帮助。

根据this discussion的说法，更正确的解决方案是将TypeScript更新到2.x分支的最新稳定次要版本，即现在(2017年2月12日)的2.1.6。生成日志中的错误表明您使用的是过时的2.0.10版本。最新的jasmine定义文件在spyOn()函数中有一个新的语法检查，该函数仅适用于TypeScript >=2.1.0。一般来说，你应该没有什么重要的理由坚持使用2.0.10，所以，请升级。但是，如果有一个向后兼容性问题阻止你升级，你应该在这里填写问题表单：https://github.com/Microsoft/TypeScript/issues，并让编译器团队意识到一个错误。

更新：避免在package.json代码行中使用以下代码："typescript": "2.0.10、"typescript": "~2.0.0"。您应该应用^限制(允许更新次版本号，而不仅仅是修补程序)，而不是~，如"typescript": ^2.0.0"。

希望这能有所帮助。很抱歉给您带来不便。

即使使用Angular 2+，我也遇到了这个问题。对我来说，解决问题的是更新Typescript，而不是降级Jasmine。

我的步骤是：

将

• package.json更改为指向新版本的typescript -> ->

​

运行npm install

• After
• 错误已经消失。
