Go pprof not working properly

Question

I'm trying to get pprof working with Golang.

--text seems to work fine but most of other options does not work.

For instance with pdf:

root@ubuntu:/home/user/IdeaProjects/go_projects/src# go tool pprof --pdf ./src /tmp/profile578584736/cpu.pprof > out.pdf
sh: 1: dot: not found
root@ubuntu:/home/user/IdeaProjects/go_projects/src# 

With gv:

root@ubuntu:/home/user/IdeaProjects/go_projects/src# go tool pprof --gv ./src /tmp/profile578584736/cpu.pprof 
sh: 1: dot: not found
gv -scale 0
Can't exec "gv": No such file or directory at /usr/local/go/pkg/tool/linux_386/pprof line 719.
root@ubuntu:/home/user/IdeaProjects/go_projects/src# 

Is there something that I need to change in Go to get it working?

对于使用自制软件的 Mac 上遇到此问题的任何人：

brew install graphviz

Answer 2

You need dot and gv installed. I see you're using Ubuntu, just try apt-get install graphviz gv

Answer 3

Got a similar error on Windows 10. I fixed it by installing graphviz from here https://graphviz.org/download/ . After that I restarted my IDE, issued the pdf and png commands and everything worked

Answer 4

Ubuntu 的另一种选择

$ sudo apt install graphviz
