Scenario:
Windows machine with
Path
environment key containing the PATH. An environment is passed in where the PATH is namedPATH
.cross-spawn
will pass an undefinedpath
intowhich
, which makeswhich
fall back toprocess.env.Path
.This is troublesome if the first hit in
options.env.PATH
is not an executable file but the first hit inprocess.env.Path
is an executable file.cross-spawn
doesn't realise it needs to wrap the command withcmd.exe
.We're running into this in yarnpkg/berry#1377, where we prepend the PATH with a folder containing
node.cmd
butcross-spawn
detectsC:\Program Files\nodejs\node.exe
instead.
