我已经安装了 d3": "^3.5.17" 和 "d3-tip": "^0.7.1" 使用 npm (d3-tip 文档.然后在我的 index.js 文件中我有这段代码:
I've installed d3": "^3.5.17" and "d3-tip": "^0.7.1" using npm (d3-tip documentation). Then in my index.js file I have this code:
var d3 = require('d3'); var d3tip = require('d3-tip')(d3); console.log('d3 version', d3.version); var tip = d3tip().attr('class', 'd3-tip').html(function(d) { return "hello world"; })但是当我使用 browserify 构建索引文件并将其加载到浏览器中时,我看到 var tip 行出现错误:
But when I build the index file with browserify and load it in the browser, I see an error from the var tip line:
index.js:247 Uncaught TypeError: Cannot read property 'node' of undefined这是来自 d3-tip 源代码中的这个函数:
This is coming from this function in the d3-tip source code:
function getSVGNode(el) { el = el.node() if(el.tagName.toLowerCase() === 'svg') return el return el.ownerSVGElement }看起来这个函数是期望一个节点被传递给它?但这是从哪里来的?
It looks like this function is expecting a node to be passed to it? But where would this come from?
构建本身不会引发任何错误,我认为我正确地需要 d3-tip,根据这个问题.控制台语句按预期显示 d3 版本 3.5.17.
The build itself does not throw any errors, and I think I'm requiring d3-tip correctly, as per this question. The console statement shows d3 version 3.5.17, as expected.
更新:这是我的 package.json 文件:
UPDATE: Here's my package.json file:
{ "name": "myapp", "version": "1.0.0", "main": "main.js", "scripts": { "test": "echo \"Error: no test specified\" && exit 1", "watch": "watchify index.js -o main.js --debug --verbose", "build": "browserify index.js | uglifyjs > main.min.js" }, "dependencies": { "d3": "^3.5.17", "d3-tip": "^0.7.1", "datatables": "^1.10.12", "datatables-bs": "^1.10.12" }, "devDependencies": { "uglifyjs": "^2.4.10", "watchify": "^3.2.1" } }我用 npm install 安装了这些文件.
And I installed the files with npm install.
推荐答案发生这种情况是因为我试图将最新版本的 d3-tip(需要 D3 的 v4)与 D3 的 v3 一起使用.
This was happening because I was trying to use the latest version of d3-tip (which requires v4 of D3) with v3 of D3.
恢复到旧版本的两个固定的东西:
Reverting to older versions of both fixed things:
"d3": "^3.5.17", "d3-tip": "^0.6.7"更多推荐
将 d3
