“TypeError: jsdom.jsdom is not a function” with paper-node.js in npm paper 模块
[英]"TypeError: jsdom.jsdom is not a function" with paper-node.js in npm paper module
问题描述
I have installed webppl-agents library (along with webppl and webppl-dp ) and am trying to run the command line test, but I'm running into some trouble.
我已经安装了webppl-agents库（以及webppl和webppl-dp ）并且正在尝试运行命令行测试，但是我遇到了一些麻烦。 It appears there is a dependency issue with jsdom from the npm paper module (1) (2) (3) (4) , but I haven't been able to get a complete handle on the issue at this point. npm 文件模块(1) (2) (3) (4) 中的jsdom 似乎存在依赖性问题，但此时我无法完全处理该问题。
Does anybody know what's going on here?有人知道这里发生了什么吗？ Do I just need to use a newer version of paper?我是否只需要使用较新版本的纸张？
PS C:\Users\user\.webppl\node_modules\webppl-agents> webppl --require webppl-dp --require . tests/tests.wppl
C:\Users\user\.webppl\node_modules\webppl-agents\node_modules\paper\dist\paper-node.js:10835
document = jsdom.jsdom('<html><body></body></html>'),
^

There has been some breaking changes recently.最近发生了一些重大变化。 The following way of initializing jsodm , document and window fixed it for me:以下初始化jsodm 、 document和window为我修复了它：
import jsdom from 'jsdom';
const {JSDOM} = jsdom;
const {document} = (new JSDOM('<!doctype html><html><body></body></html>')).window;
global.document = document;
global.window = document.defaultView;
