typescript [at-loader] node_modules\@types\jasmine 中的错误

ERROR in [at-loader] node_modules\@types\jasmine

提问by Josh

My webpack build started failing out of nowhere with no packages being updated. I assume some minor version update caused this, but can't figure out how to get around it. Does anyone know what to do?

我的 webpack 构建开始突然失败，没有更新任何包。我假设一些小版本更新导致了这个，但无法弄清楚如何解决它。有谁知道该怎么做？

Looks like your @types/jasminelibrary was upgraded to the latest version since you have the caret symbol:

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",

The latest version is having issues as this bugsuggests. So try for now by setting the version to 2.5.41 in your package.json :

正如此错误所暗示的那样，最新版本存在问题。所以现在尝试通过在 package.json 中将版本设置为 2.5.41 ：

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

Maybe you have to delete your node-modulesfolder and run npm installfor a clean installation.

也许您必须删除node-modules文件夹并运行npm install以进行全新安装。

If you're not using Angular 2, update your TypeScript to 2.1.6 or higher, please. This should help.

如果您没有使用 Angular 2，请将您的 TypeScript 更新到 2.1.6 或更高版本。这应该有帮助。

According to this discussion, a more correct solution is to keep TypeScript updated to the latest stable minor version of 2.xbranch, which is 2.1.6as of now (Feb 12, 2017). The error you have in a build log indicates that you are using an outdated 2.0.10version. The latest jasminedefinition file has a new syntax check in spyOn()function which is available only for TypeScript >=2.1.0. Generally, you should have no serious reason to stick to 2.0.10, so, please upgrade. However, if there's a backward compatibility issue preventing you from the upgrade, you should fill in the issue form here: https://github.com/Microsoft/TypeScript/issuesand make the compiler team aware of a bug.

根据此讨论，更正确的解决方案是将 TypeScript 更新到最新的稳定次要2.x分支版本，即2.1.6截至目前（2017 年 2 月 12 日）。您在构建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定义文件有一个新的语法检查spyOn()功能，仅适用于 TypeScript >=2.1.0。一般来说，你应该没有严重的理由坚持2.0.10，所以，请升级。但是，如果存在阻止您升级的向后兼容性问题，您应该在此处填写问题表：https: //github.com/Microsoft/TypeScript/issues并使编译器团队意识到错误。

UPD: Avoid in your package.jsonlines like these: "typescript": "2.0.10, "typescript": "~2.0.0". Instead of ~you should apply ^restriction (allows to update minor version numbers, not only hotfixes) like "typescript": ^2.0.0".

UPD：避免在您的package.json行中使用："typescript": "2.0.10, "typescript": "~2.0.0". 而不是~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"typescript": ^2.0.0".

Hope that helps. Sorry for the inconvenience.

希望有帮助。带来不便敬请谅解。

Even with Angular 2+ I had this problem. What solved the problem to me, instead of downgrading Jasmine was updating Typescript.

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。

My steps were:

我的步骤是：

• Change package.jsonto point to a new version of typescript
  • "typescript": "~2.0.9"-> "typescript": "^2.0.9"
• Run npm install
• After this the error was gone.

• 更改package.json为指向新版本的打字稿
  • "typescript": "~2.0.9"-> "typescript": "^2.0.9"
• 跑 npm install
• 在此之后，错误消失了。
