【问题描述】：
我有 create-react-project v15 并运行 npm run build 并需要很长时间（20 分钟）（如冻结）运行构建然后得到这个错误结果。
如何解决这个问题？

【问题讨论】：
-
线索在错误“extractedChunk.getNumberOfModules is nota function”中。您可能没有正确导出该函数，但没有看到您的代码就无法判断。
-
这个 package-module 来自 create react app module => extract-text-webpack-plugin。我不知道修复
-
我的猜测是你应该将提取的Chunk.getNumberOfModules() 更改为extractChunk.getNumberOfModules ，不带()
-
@MihaiT 我在你的指导下改变了结果是一样的。冻结构建
-
我看到了这个确切的问题 - 有什么进展吗？
