我将一个大型组件库与 webpack 捆绑在一起，并导出到一个文件，然后我尝试在我的 React 应用程序中测试该文件。 webpack 输出文件没有问题。当我运行 npm link 并模拟模块导入时，问题出现了。
我可以在开发中启动，只需导入我的本地组件即可。
从“./components”导入{App}； // 工作正常 从“testlib”导入{App}； // 抛出错误
我确定我在 webpack 中做错了什么，只是不知道是什么。任何帮助将不胜感激。
请参阅下面的错误：

我已经确认它来自这个代码片段（我很确定这是来自 React 开发服务器），我只是不知道如何修复它：
'use strict';
var has = require('has');
function specifierIncluded(current, specifier) {
var nodeParts = current.split('.');
var parts = specifier.split(' ');
var op = parts.length > 1 ? parts[0] : '=';
var versionParts = (parts.length > 1 ? parts[1] : parts[0]).split('.');
for (var i = 0; i < 3; ++i) {
var cur = parseInt(nodeParts[i] || 0, 10);
var ver = parseInt(versionParts[i] || 0, 10);
if (cur === ver) {
continue; // eslint-disable-line no-restricted-syntax, no-continue
}
if (op === '<') {
return cur < ver;
}
if (op === '>=') {
return cur >= ver;
}
return false;
}
return op === '>=';
}
function matchesRange(current, range) {
var specifiers = range.split(/ ?&& ?/);
if (specifiers.length === 0) {
return false;
}
for (var i = 0; i < specifiers.length; ++i) {
if (!specifierIncluded(current, specifiers[i])) {
return false;
}
}
return true;
}
function versionIncluded(nodeVersion, specifierValue) {
if (typeof specifierValue === 'boolean') {
return specifierValue;
}
var current = typeof nodeVersion === 'undefined'
? process.versions && process.versions.node
: nodeVersion;
if (typeof current !== 'string') {
throw new TypeError(typeof nodeVersion === 'undefined' ? 'Unable to determine current node version' : 'If provided, a valid node version is required');
}
if (specifierValue && typeof specifierValue === 'object') {
for (var i = 0; i < specifierValue.length; ++i) {
if (matchesRange(current, specifierValue[i])) {
return true;
}
}
return false;
}
return matchesRange(current, specifierValue);
}
var data = require('./core.json');
module.exports = function isCore(x, nodeVersion) {
return has(data, x) && versionIncluded(nodeVersion, data[x]);
};

我在使用“twin.macro”时遇到了类似的错误。
在我的 webpack 配置文件中，我对“.jsx”文件使用“babel-loader”，对“.tsx”文件使用“ts-loader”。
我通过使用“babel-loader”处理“.jsx”和“.tsx”文件来修复错误，如下所示：
{
test: /\.[jt]sx?$/,
exclude: /node_modules/,
use: ["babel-loader"],
}
这并不理想，因为我将“ts-loader”与“fork-ts-checker-webpack-plugin”一起使用来减少编译时间。但对我来说，能够使用“双宏”更重要，所以......
我也有同样的问题。安迪有更新吗？
