[web] FileSystemException: Cannot open file #45798
Description
Multiple dart.exe processes were started in the background When I run 'flutter run -d chrome', leading to an error:
FileSystemException: Cannot open file, path =
'C: \ Users \ chenwanjin \ AppData \ Local \ Temp \ scratch_spaceada79580-1272-11ea-a949-c46516304869 \ packages \ flutter \ src \ gestures \ arena.ddc.js' (OS Error: Another program is using this file, The process is inaccessible.
, errno = 32).
Here is my terminal log:
