类型错误:无法调用未定义的方法“charCodeAt" [英] TypeError: Cannot call method 'charCodeAt' of undefined

问题描述

我用 webpack 创建了一个裸项目，只有一个加载器，ts-loader.由于以下错误，Webpack 失败:

I created a bare project with webpack with only one loader, ts-loader. Webpack is failing due to the following error:

ERROR in ./app.ts
Module build failed: TypeError: Cannot call method 'charCodeAt' of undefined
    at getRootLength (/home/ravioli/IdeaProjects/dummyWebpack/node_modules/ts-loader/node_modules/typescript/bin/typescript.js:997:18)
    at Object.isRootedDiskPath (/home/ravioli/IdeaProjects/dummyWebpack/node_modules/ts-loader/node_modules/typescript/bin/typescript.js:1051:16)

在原生 Javascript 文件上测试时，Webpack 按预期运行.错误发生在使用 Typescript 文件和 ts-loader 时，错误的来源是(正如您在堆栈中看到的).

When tested on vanilla Javascript files Webpack runs as expected. The error occurs when working with Typescript files and the ts-loader, where the origin of the error is (as you can see in the stack).

删除以下行后问题解决:///(文件的内容不影响错误 - 我已经检查过).

Problem solves once removing the following line: ///<reference path="testi.d.ts" /> (The content of the file does not affect the error - I've checked).

这是示例项目的链接，从 src_ts 文件夹运行 webpack:https://github.com/ravitb/dummyWebpack

Here is a link to the example project, run webpack from the src_ts folder: https://github.com/ravitb/dummyWebpack

我在这里错过了什么?！

What am I missing here?!

推荐答案

这是一个问题，其中 ts-loader 引入了 TypeScript 1.5，该问题具有重大更改，而不是坚持使用 TypeScript 1.4.我已经推出了一个新版本(0.3.4)来解决这个问题.抱歉出现问题.

This was an issue where ts-loader was pulling in TypeScript 1.5 which had breaking changes instead of sticking with TypeScript 1.4. I've pushed out a new version (0.3.4) that should take care of this. Sorry for the problem.
