Jest从node_modules组件意外导入令牌；babel无法运行？
Jest从node_modules组件意外导入令牌；babel无法运行？
提问于 2017-05-19 01:53:04
我正在尝试弄清楚如何让Jest在我的环境中工作，我遇到了一个问题，这个项目在node_modules中的一个子目录中有一堆自定义组件。
我得到了这个错误：
FAIL src/mantle/tools/searchindexer/apps/DataMover/js/components/__test__/GenericJobsTable.test.jsx
● Test suite failed to run
/Users/rob/repos/mesa/ui/node_modules/iggy-common/components/IggyTable.jsx:1
({"Object.":function(module,exports,require,__dirname,__filename,global,jest){import React, {PropTypes} from "react";

Ran all test suites matching "GenericJobsTable".我在NodeJS 7.7.1上运行jest ^20.0.3和babel-jest ^20.0.3。
在我的package.json中，这是我拥有的jest配置节：
"jest": {
"verbose": true,
"transform": {
"^.+\\.jsx$": "babel-jest"
},
"moduleFileExtensions": [
"js",
"jsx"
],
"moduleDirectories": [
"node_modules"
]
}我将根.babelrc定义为：
{
"presets": ["es2015", "react"]
}如果我运行jest --debug，我会看到以下内容：

}你知道我在这里可能配置错了什么吗？

解决了！问题是node_modules/iggy common中的一个讨厌的文件是一个需要转换的普通的ol文件：
"jest": {
"verbose": true,
"transform": {
"^.+\\.jsx$": "babel-jest",
"^.+\\.js$": "babel-jest"
},
"moduleFileExtensions": [
"js",
"jsx"
],
"moduleDirectories": [
"node_modules"
],
"transformIgnorePatterns": [
"node_modules/(?!iggy-common)"
]
