chai.expect(singleContextHTML._strategyPeak()).to.equal('SingleContextHTML');

我正在尝试测试策略模式的实现,但是在我使用 mocha 运行测试脚本后遇到了一个错误,指出以下内容。
var singleContextHTML = new _PortalHTML2.default("1");
^
TypeError: _PortalHTML2.default is not a constructor
我正在使用 node6 和以下 babel 包:
"babel-cli": "^6.14.0",
"babel-core": "^6.17.0",
"babel-loader": "^6.2.4",
"babel-preset-es2015": "^6.16.0",
"babel-preset-react": "^6.11.1",
"babel-preset-stage-2": "^6.11.0"
我已经尝试调试了大约半天。如果有人立即发现我做错了什么,我会非常感激不尽。
【问题讨论】:
-
import PortalHTML from "PortalHTML";似乎包含错误的模块标识符。 -
你的意思是
from "./ProtalHTML"吗? -
是的,对于这个玩具示例,在我的实际代码中,目录结构是正确的。我更新以防止混淆。对此感到抱歉
