1. Re-delete node_moudule, re-download, the installation package will sometimes have an inexplicable bug, installed, start
2. Download the child_process installation package, and then start
to compare svn with the previous version, and found that there is a file import a package, which may have been accidentally clicked to, and the editor automatically completes it. Resolved. Thank you. @ Rabbit loves to eat pears
delete both node_moudule and package.lock.json, and try again npm install .
