当我使用Webpack2编译我的文件时。它显示了以下警告:
" loaderUtils.parseQuery()收到一个非字符串值,可以是 有问题,请参阅https://github.com/webpack/loader-utils/issues/56"
我检查了github页面,但没有找到解决此问题的方法。这是我的配置:

loaderUtils.parseQuery()
来获取传递给加载器的选项。它已被loaderUtils.getOptions()
取代。您可能正在使用仍使用parseQuery
的加载程序。您在webpack配置中使用的所有加载器应该已更改为使用getOptions
,但您可能正在使用不包含更改的旧版本。要解决此问题,您只需将装载程序升级到最新版本即可。
如果由于某种原因您不想升级所有加载器,可以在webpack配置文件中添加以下行(不作为选项):
process.traceDeprecation = true;
这将为您提供使用parseQuery
的堆栈跟踪,以便您可以识别实际使用它的加载程序并升级该特定的加载程序。
事实证明,最新的babel-loader
仍使用parseQuery
,它将在下一个主要版本中更改,并且已在v7.0.0-alpha中提供。但是如果您不想使用alpha版本,则必须使用警告,直到v7.0.0
出现。
