"Could not find Opera binary" error in Python

[einsteinsfool]

I wrote this code using Python bindings:

from selenium import webdriver

browser = webdriver.Opera()
browser.get('http://seleniumhq.org/')
browser.quit()

...and got the following error:

Traceback (most recent call last):

same issue..

[abdelhamidlinux5765]

hello, i am running r windows 3.4 in linux by wine and i have this issue when trying to open opera using linux for operadriver.

[ghost]

Hey guys, I got it working:

alan@kaiju:~ (1021)% opera --version
44.0.2510.1218
alan@kaiju:~ (1022)% operadriver --version
OperaDriver 2.27 (f61056e560d197467fd6d27c7fbd7fea572fe8bd)
alan@kaiju:~ (1023)% python3 --version                            
Python 3.5.2+
alan@kaiju:~ (1024)% ipython3

<snip>

In [1]: import selenium

In [2]: selenium.__version__
Out[2]: '3.3.1'

In [3]: from selenium import webdriver

In [4]: options = webdriver.ChromeOptions()

In [5]: options.binary_location = "/usr/bin/opera" # path to opera executable, even though it's in PATH :/

In [6]: driver = webdriver.Opera(opera_options=options) # success!

Try this.

I don't know Java or R. I'd suggest opening another issue since this is a Python thread.

Hi! Are you still experiencing the issue mentioned in the OP with the latest operadriver releases?

[tompil]

@wladzynski Could you reopen the issue? I have the same problem. Running the similar code results an error.

I tried the solution that was proposed by @duanzhijie861229 and it has produced a very interesting error message. See output below:

As you can see the "\51." in the path has been miss interpreted into ")" in the defined path "\51." is in line 5 ")" is in line 23

[tompil]

Use a double backslash instead of single one. \51 in a string literal is an escape sequence, which produces ')' (which has code 51 in octal representation in ASCII table). This is not good idea to hardcode the path in a script. It's more flexible to use a config file or set an environment variable.

[duanzhijie861229]

something wrong happen when i upload the code"D:\\Program Files\\Opera1\\50.0.2762.58\\opera.exe" you can change your code to:options.binary_location = "c:\\Program Files\\Opera\\51.0.2830.40\\opera.exe"or options.binary_location = "c:/Program Files/Opera/51.0.2830.40/opera.exe"

[buscseik]

Yep, I know, I have option to use\\ or even / to avoid this problem in this example. But what I want to highlight here, this is a bug! Why opera driver/python connector does not handle this type of input on correct manner.

To put my problem into context. I use selenium in Robotframework. In that, I do not have option to define the custom path. This will be done by the Python selenium connector and it is based on system PATH.

[einsteinsfool]

I still have this issue with: Python 3.6.4 Operadriver 2.33 Python bindings 3.10.0 Opera 51.0.2830.40 Linux 64bit

It works with mentioned by ghost hotfix:

from selenium import webdriver

options = webdriver.ChromeOptions()
options.binary_location = "/usr/bin/opera" # getting error without this line
browser = webdriver.Opera(options=options)
browser.get('http://seleniumhq.org/')
browser.quit()

Specifying binary location shouldn't be necessary.

thanks bro

[FedFabFrat]

hi, following the solution of ghost, and I am prompted the following error:

_WebDriverException: unknown error: Opera failed to start: exited normally (unknown error: DevToolsActivePort file doesn't exist) (The process started from chrome location C:\Users\feder\AppData\Local\Programs\Opera\launcher.exe is no longer running, so OperaDriver is assuming that Opera has crashed.) (Driver info: OperaDriver=2.42.3135 (O58),platform=Windows NT 10.0.17763 x8664)

Any ideas?

[UzaeirAzhar]

For me same error appeared. But then I changed my binary location to e.g:

C:\\Users\\UK\\AppData\\Local\\Programs\\Opera\\58.0.3135.65\\opera.exe

Then it works. Check your location and try to replace it.

[ikostan]

Hi all. I just wonder is there any hope that one day this issue will be fixed and we will no longer required to specify options.binary_location? I mean, all other drivers know how to find the binary by the default install path... Thanks.
