What did you expect to see and what you saw instead?

steve@tr4:~/go$ go get github.com/zserge/webview

pkg-config --cflags -- gtk+-3.0 webkit2gtk-4.0

Package webkit2gtk-4.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `webkit2gtk-4.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'webkit2gtk-4.0' found
pkg-config: exit status 1

Could you provide instructions on how to resolve this on Debian?

libwebkit2gtk-4.0-dev should provide the pkg-config file (see here):

sudo apt-get install libwebkit2gtk-4.0-dev

[eneukirchner]

Does not work on fedora 29 because there is no webkit2gtk-4.0-devel.

[guilhermeg2k]

[UmSergDev]

same problem under mac os x 10.14.4, PKG_CONFIG_PATH variable setuped

[vitalyster]

@UmSergDev you should define WEBVIEW_COCOA and it will use native WebView instead of webkit2gtk

[Akiyamka]

fixed installing this https://fedora.pkgs.org/29/fedora-updates-x86_64/webkit2gtk3-devel-2.22.7-1.fc29.x86_64.rpm.html

Fedora 31, i fix issue with
sudo dnf install webkit2gtk3-devel.x86_64

Hi, I am having the same issue on fedora 35 but the previously mentioned package mentioned by @Akiyamka doesn't seem to fix it. What am I missing?

Package webkit2gtk-4.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `webkit2gtk-4.0.pc'
to the PKG_CONFIG_PATH environment variable

@Ezema Does this package fix it? https://fedora.pkgs.org/35/fedora-x86_64/webkit2gtk3-devel-2.34.0-1.fc35.x86_64.rpm.html

[Ezema]

@justjosias No it doesn't unfortunately

Facing the same issue here. I've tried removing the package and reinstalling it but the problem persists.

pwd -> /usr/lib64

When running tree | grep webkit in current directory, I found webkit2gtk-4.0.pc:

Yet when trying to cd into libwebkit2gtk-4.0.so.37.55.4 or cat libwebkit2gtk-4.0.so.37.55.4/webkit2gtk-4.0.pc, I get prompted with libwebkit2gtk-4.0.so.37.55.4/webkit2gtk-4.0.pc: Not a directory

[F-Persson]

The one-liner that resolved the issue for me

sudo dnf install webkit2gtk3-devel

[SteffenL]

I am going to close this because solutions have already been posted. In addition the current project readme has information for both Debian- and Fedora-based systems.
