Failed to parse source map from '/xxx/dist/MutationObserver.js'

[nanianlisao]

hey, I received a warning in the terminal console，as follows

warning  in ./node_modules/mutationobserver-shim/dist/mutationobserver.min.js

Module Warning (from ./node_modules/source-map-loader/index.js):
Failed to parse source map from '/Users/xxx/node_modules/mutationobserver-shim/dist/MutationObserver.js' file: Error: ENOENT: no such file or directory, open '/Users/xxx/node_modules/mutationobserver-shim/dist/MutationObserver.js'

Can you help me? I haven't found the answer anywhere else

Copy the 'MutationObserver.js' file to the ./dist directory

let source-map-loader or webpack ignore this error ！
