我正在努力将ReactJS应用程序引入.NET设置。我正在尝试从任务运行器(或VS中的任何位置)运行NPM脚本。当我从任务运行器运行我的构建命令时,由于我的一个脚本中的ES6箭头功能,它会失败。但是,如果我加载cmd.exe
或powershell,导航到项目并手动运行它,它运行完美。
任何想法为什么Visual Studio会这样做?
输出看起来像这样:
> cmd.exe /c npm run build --color=always
> ...cmd1
> ...cmd2
> mocha --reporter spec tools/testSetup.js "Scripts/app/**/*.test.js"

它出错的文件基本上只是设置JSDOM:
process.env.NODE_ENV = 'test';
// Register babel so that it will transpile ES6 to ES5
// before our tests run.
require('babel-register')();
// Disable webpack-specific features for tests since
// Mocha doesn't know what to do with them.
require.extensions['.css'] = function () {return null;};
require.extensions['.png'] = function () {return null;};
require.extensions['.jpg'] = function () {return null;};
// Configure JSDOM and set global variables
// to simulate a browser environment for tests.
var jsdom = require('jsdom').jsdom;
var exposedProperties = ['window', 'navigator', 'document'];
global.document = jsdom('');
global.window = document.defaultView;
Object.keys(document.defaultView).forEach((property) => {
if (typeof global[property] === 'undefined') {
exposedProperties.push(property);
global[property] = document.defaultView[property];
}
});
global.navigator = {
userAgent: 'node.js'
};
documentRef = document; //eslint-disable-line no-undef
同样,我可以直接从CLI运行它,它会起作用。它调用了babel寄存器。我只是不确定为什么要在这里犯错误。如果我用常规函数换出箭头函数,我在测试中会遇到其他错误,所以就像任务运行器无法找到babel,或者正在失去一些环境设置。
