os info：CentOS-7-x86_64

I have installed requirements

[root@localhost package]# rpm -qa | grep gtk
libwebkit2gtk-2.4.9-6.el7.x86_64
gtk3-devel-3.14.13-20.el7.x86_64
gtk3-3.14.13-20.el7.x86_64
gtk2-2.24.28-8.el7.x86_64
webkitgtk3-devel-2.4.9-6.el7.x86_64
webkitgtk3-2.4.9-6.el7.x86_64

When I do

go get github.com/sourcegraph/webloop

I get the following error message

[root@localhost package]# go get github.com/sourcegraph/webloop/
# pkg-config --cflags javascriptcoregtk-4.0
Package javascriptcoregtk-4.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `javascriptcoregtk-4.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'javascriptcoregtk-4.0' found

package javascriptcoregtk-4.0 is not found

[root@localhost package]# find / -name "*javascriptcoregtk*"

How to solve this problem?

I just reverted another PR that might have caused this: sqs/gojs#4. Can you try again after running go get -u github.com/sqs/gojs?
