我有一个使用webpack进行转译的TypeScript项目,构建任务由gulp驱动。这里以一个简单的任务来展示我的问题:
var webpack = require('webpack');
var webpackStream = require("webpack-stream");
gulp.task("check", function() {
return gulp.src("*")
.pipe(webpackStream(require("./webpack.config.js"), webpack))
.pipe(gulp.dest(OUTPUT_DIR));
}
);
现在当一切正常时,gulp check
可以正常工作。现在假设我犯了一些编码错误 - 这个 gulp 任务将会发出:
[10:20:02] Starting 'check'...
[hardsource:chrome] Tracking node dependencies with: yarn.lock.
[hardsource:chrome] Reading from cache chrome...
(node:20232) UnhandledPromiseRejectionWarning
(node:20232) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 1)
(node:20232) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
[10:20:08] The following tasks did not complete: check
[10:20:08] Did you forget to signal async completion?
这个信息很不明确。如果我从检查任务中移除
.pipe(gulp.dest(OUTPUT_DIR));
,那么我就能看到原始的错误信息了。比如:[10:35:42] Starting 'check'...
[hardsource:chrome] Tracking node dependencies with: yarn.lock.
[hardsource:chrome] Reading from cache chrome...
[10:35:48] 'check' errored after 5.96 s

在webpackStream之前或之后向gulp-load-plugins.logger
添加管道无法解决问题。我能将gulp流导入到gulp.dest中,仍然能获得详细的webpack错误信息吗?如何做到?
