This error typically comes from the incompatible browser; only Chrome is supported. Can you confirm this issue with the latest stable version of Chrome? What version do you use?

The fact that firefox doesn't work is explicitly documented:

Note that while the various profiles available when launching 'go tool
trace' work on every browser, the trace viewer itself (the 'view trace'
page) comes from the Chrome/Chromium project and is only actively tested on
that browser.

Chrome, on the other hand, should work.

ALTree on 29 Apr 2018

We could check if tracing tool is available in the browser, and give an explicit error message to the user if it is not. That blank page was very confusing for me too the first time I tried to use it.

AlekSi on 29 Apr 2018

my chrome version
Version 66.0.3359.139 (Official Build) (64-bit)
it's the latest

It works for me. Can you please provide a small self-contained example demonstrating the problem?

AlekSi on 29 Apr 2018

Are you sure the m.trace file is not empty? Can you attach it?

ALTree on 29 Apr 2018

i recently run a windows 10 vm and setup golang,google chrome and the file works well ,
it can help me for now , but i need it to run on my ubuntu machine

@tarekbadrshalaan
Can you check if trace_viewer_lean.html is available from your $GOROOT/misc/trace directory?

$ ls go env GOROOT/misc/trace

hyangah on 1 May 2018

@hyangah
i have no directory $GOROOT/misc/trace
and no directory $GOROOT/misc

@tarekbadrshalaan I don't see how that's possible... please post here the output of go env.

What does ls /usr/lib/go-1.10 print?

Did you install Go from your OS package manager?

ALTree on 2 May 2018

output of ls /usr/lib/go-1.10

here how i installed go on Ubuntu
sudo add-apt-repository ppa:longsleep/golang-backports
sudo apt-get update

Please try installing the official distribution per the instructions at https://golang.org/doc/install and see if you can still reproduce the problem.

ok it's working now with go installation from the official distribution on ubuntu/chrome
thank you

fedora 29 has a separate rpm for "misc":
dnf install golang-misc

Hello. I also got this problem.

What version of Go are you using (go version)?
1.13.6 (dnf install golang)

Does this issue reproduce with the latest release?
yes (from fedora repos that is)

What operating system and processor architecture are you using (go env)?
linux / amd64 (fedora 31)

What did you do?
run a unittest writing trace to file, then running go tool trace trace.out and firefox automatically opens. I clicked on "View Trace".

What did you expect to see?
the contents of "view trace" for my unittest.

What did you see instead?
nothing, an empty, white page in firefox (Mozilla Firefox 71.0)
In the firefox console I get:

ReferenceError: tr is not definedtrace:59:5
    onResult http://127.0.0.1:33971/trace:59
    onreadystatechange http://127.0.0.1:33971/trace:43

It seems I am also missing the misc folder:

$ go env GOROOT
/usr/lib/golang

$ stat /usr/lib/golang/misc
stat: cannot stat '/usr/lib/golang/misc': No such file or directory

I removed the golang package dnf remove -y golang and installed it from https://golang.org/doc/install using go1.13.8.linux-amd64.tar.gz. Now I have the misc folder:

$ go env GOROOT  
/usr/local/go

$ stat `go env GOROOT`/misc
  File: /usr/local/go/misc
...

However, this doesn't fix the problem with an empty page in Firefox. When I launch the trace I get the same empty page with the same error message in the console. I see from #34374 and _@hyangah in https://github.com/golang/go/issues/34374#issuecomment-589261866_ that it is not yet fixed in any stable download.

Updated
The workaround from _@jpvillaseca in https://github.com/golang/go/issues/34374#issuecomment-589022051_ works on my go1.13.8 manual install.

Thank you very much.
I tried gotip on Macos and Centos. gotip works on Macos, but failed on Centos when I called gotip download.

It complains:

Updating the go development tree...
HEAD is now at 26154f3... cmd/compile: use NEG/NEGW pseudo-instructions on riscv64

gotip: failed to cleanup git repository: exit status 129

Do you hava any suggestion?

I tried gotip on centos. There is something wrong with gotip download:

Do you have any solution about how to fix this?

Alex-duzhichao on 16 Mar 2020

Please file a separate bug to track the gotip issue. cc @FiloSottile

If gotip doesn't work, an alternative is to build from the source. The instruction is https://golang.org/doc/install/source

I think the minor version release will be available soon and include the fix. But I don't know the concrete timeline yet cc @andybons

hyangah on 16 Mar 2020

It is OK on Macos:
go 1.14.4
firefox 77.0.1 (64 bit)
