有没有办法在 TypeScript 2+ 中全局添加类型定义? [英] Is there a way to add type definition globally in TypeScript 2+?
问题描述
我有一堆简单的 .ts 文件.非项目(即独立的 .ts 脚本).他们使用一些 node.js 功能.TypeScript 和节点类型定义通过
I have a bunch of simple .ts files. NOT projects (i.e. standalone .ts scripts).
They use some node.js functionality.
TypeScript and node type definitions are installed via
npm install -g typescript
npm install -g @types/node
问题:在 Windows 上我可以毫无问题地运行 tsc foo.ts.它可以很好地将 .ts 转换为 .js.但是在 Ubuntu 16.04 上，它给了我 error TS2304: Cannot find name 'require'、error TS2304: Cannot find name 'process' 等.即使将 /// 添加到 foo.ts 的顶部或添加 --types node> 切换到 tsc 我收到 错误 TS2688:找不到节点"的类型定义文件.
Problem: on windows I can run tsc foo.ts with no problems. It transpiles .ts to .js just fine.
But on Ubuntu 16.04 it gives me error TS2304: Cannot find name 'require', error TS2304: Cannot find name 'process' and etc.
Even if add /// <reference types="node" /> to the top of foo.ts or add --types node switch to tsc I get error TS2688: Cannot find type definition file for 'node'.
看起来在 Windows 中全局安装某些类型可以正常工作，但在 Ubuntu 上则不行，所以我假设这不是设计使然.那么有没有办法全局安装它们?或者更准确地说:在 Ubuntu 上引用全局安装的类型定义?
It looks like installing some types globally works fine in Windows but not on Ubuntu, so I'm assuming that this is not by design. So is there a way to install them globally? Or more precisely: to reference globally installed type definitions on Ubuntu?
推荐答案
我找到了解决方案.我必须手动指定 typeRoots 和通向 npm 安装的全局包的路径.像这样:tsc --typeRoots/usr/lib/node_modules/@types(您可以通过 npm root -g 获取系统路径).
I found the solution. I had to manually specify the typeRoots with the path leading to there npm installed global packages.
Like so: tsc --typeRoots /usr/lib/node_modules/@types (you can get the path for your system via npm root -g).
仍然不知道为什么它在 Windows 上没有任何特殊工作的情况下查找它们，而在 Ubuntu 上没有.不知道是不是bug，不知道是哪个版本.
Still not sure why it looks them up without any special work on Windows and doesn't on Ubuntu. Can't tell if it's a bug and if it is then in which version.
