如何在节点和打字稿项目中导入d3.js? [err_require_esm]
我正在使用TypeScript,OCLIF和D3.JS等节点项目。用
无论如何,一切都很好,但是我最近添加了D3作为依赖项并尝试构建文档,并且在运行它时会遇到此错误:
(node:22554) [ERR_REQUIRE_ESM] Error Plugin: dbacl [ERR_REQUIRE_ESM]: require() of ES Module /dbacl/node_modules/d3/src/index.js from /dbacl/src/tree/graph-tree.ts not supported.
Instead change the require of index.js in /Users/nico/Furo/Dev/dbacl/src/tree/graph-tree.ts to a dynamic import() which is available in all CommonJS modules.
在我使用D3的文件中,我将其导入为 pher文档:
import * as d3 from 'd3'
我怀疑编译后可能是一个问题,所以这里是tsconfig.json
。自NPX发电以来,我没有改变任何事情。

如果它更相关,这是我的package.json

我发现这个问题很困惑,因为我到处都在搜索这个问题,似乎我在做正确的事。我认为问题可能在我的屏幕和椅子之间,但实际上我不明白。另外,我应该使用这样的动态导入吗?
const d3 = await import('d3')
我尝试过,它不起作用。我制作了生成文档异步的函数,并在开始时添加了该行。无论如何,如果我相信这个错误,那将是要解决的路,但是在寻找解决方案的解决方案时,我没有看到这个解决方案。你们怎么看?
谢谢
I'm working on a node project using typescript, oclif and d3.js, among other things. Typescript was configured by npx when creating the project with oclif so I didn't control all aspects of it (especially regarding TS, and I'm not an expert. TS is great, but configuration wise, meh).
Anyway, everything was working fine, but I recently added d3 as a dependency and tried to build a document, and I get this error when running it:
(node:22554) [ERR_REQUIRE_ESM] Error Plugin: dbacl [ERR_REQUIRE_ESM]: require() of ES Module /dbacl/node_modules/d3/src/index.js from /dbacl/src/tree/graph-tree.ts not supported.
Instead change the require of index.js in /Users/nico/Furo/Dev/dbacl/src/tree/graph-tree.ts to a dynamic import() which is available in all CommonJS modules.
In the file where I'm using d3 I import it as per documentation:
import * as d3 from 'd3'
I suspect it might be a problem after compiling, so here is tsconfig.json
. I didn't change anything since generation by npx.

And in case it's more relevant, here is my package.json

I find this problem quite confusing because everywhere I've been searching about this problem, it seems I'm doing the right thing. I assume the problem might be between my screen and my chair, but really I don't get it. Also, should I use the dynamic import like this?
const d3 = await import('d3')
I tried, it didn't work. I made the function that generates the document async and added that line at the start but nope. Anyway, if I believe the error, that would be the way to go but I didn't see this solution anywhere when looking for a solution to my problem. What do you guys think?
Thanks

因此,感谢同事的输入和本文,问题是现在D3仅支持ESM。因此,当编译器将导入转入其中时,
就无法正常工作。我正在使用D3版本7,而它的快速修复是在支持CommonJ时降级到版本
6.7.0
。现在,我必须继续进行此项目,但是我将继续研究它,并如何在项目中使用D3的最新版本。如果我这样做,我将编辑这个答案!
干杯
So thanks to the input from a colleague and this article, the problem is that d3 now supports ESM only. So when the compiler turns the import into
it just doesn't work. I was using d3 version 7, and a quick fix to it was to downgrade to version
6.7.0
, when it did support commonJS.Now, I have to move on with this project, but I'll keep looking into it and into how I can use a recent version of d3 in my project. If I do, I'll edit that answer!
Cheers
