从8升级到9后无法构建Angular项目

Question

我已经使用ng更新工具将Angular项目从8升级到9。本地（Windows）一切正常，但是当我试图在docker中构建项目时，我得到以下错误：

Step 6/11 : RUN npm run build

dockerfile：

我能做些什么来修复它？角度8的图像很好。我尝试了不同的节点图像，但没有任何帮助。。。

我不确定您的问题是什么，或者是什么原因造成的，但是我快速搜索了一下，偶然发现了这个github问题。它涉及并行构建（我不认为这是您的情况），但我认为它仍然可以应用于这里，因为错误发生在angular core的编译过程中。

建议的解决方法是将角兼容性编译器（ngcc）作为postset脚本运行，而不是让构建本身触发它。

修改您的package.json文件，并将以下内容添加到脚本部分：

"postinstall": "ngcc
