Question

我试图将我的角度5代码迁移到角度6。

将elasticsearch客户端从“elasticsearch”：“^ 14.2.1”迁移到“elasticsearch”：“^ 14.2.2”后，我得到以下错误，同时启动角度代码。

npm start

ERROR in ./node_modules/elasticsearch/src/lib/utils.js
Module not found: Error: Can't resolve 'path' in 
'\ui_angular_6\node_modules\elasticsearch\src\lib'
: Failed to compile.
