SImple way to solve it is :
$ cd /
$ cd usr/local/var/run/watchman/
$ ls
<user>-state
MacBook-Pro:watchman user$ rm -rf <user>-state/
If not then,
1. increase max file limit
# check open file limit
sysctl kern.maxfiles
# edit sysctl
sudo vim /etc/sysctl.conf
# add these two lines
kern.maxfiles=10485760
kern.maxfilesperproc=1048576
# reboot
sudo reboot
# check new file limit
sysctl kern.maxfiles
2. upgrade to watchman 4.6
# clone repo
git clone https://github.com/facebook/watchman.git
# change to master branch
git checkout -b v4.6.0 v4.6.0
# run compiler
./autogen.sh
./configure --enable-lenient --without-pcre --with-python
make
sudo make install
# check watchman version
watchman -v
# result should be 4.6.0
