无法使用webpack2生成外部源映射

时间：2017-04-18 16:11:10

标签： angular typescript webpack webpack-2 source-maps

将Angular项目从webpack1迁移到webpack2后，我遇到了一个问题。 除了源图之外，一切都很顺利。 它在我的JS文件中嵌入一个sourcemap作为base64编码的字符串。 它当然会创建疯狂的大文件。

我希望在prod中有单独的地图文件。 但是，我控制源映射生成的所有尝试均未成功。 我试图用uglifyjs禁用它们，我试图在tsconfig.json中禁用它们，当然我玩的是devtool参数，它被设置为＆source-map＆＃39;。 我已经尝试了我能想到的一切。 我也试图改变我的打字机加载器，没有结果。

我的印象是我的行为与我选择＆＃39; inline-source-map＆＃39;而不是＆source-map＆＃39;。

这是我的webpack配置以及我的tsconfig和package.json

提前感谢您的帮助！

答案 0 :(得分：0)

终于找到了问题。 我将参数-d传递给webpack。 这恰好强制源地图行为。

切换到-p并且它好多了。当然。

我保留它，以防它帮助某人。 我非常关注配置，我忘记了控制台的论点。
