ideas ?

[vividhsv]

Looks like you are using python 3.4. Locust does not support python3.x yet.

You should use python2.7.

[dotpot]

Oh i see, any ETA on py3 support ? Anyone is working on it already ?

[vividhsv]

No ETA defined yet, get more info on #279

[eyalev]

Happened to me as well. Was fixed after I re-entered the shell.

[jleclanche]

README.md says Locust works on Python 3.4 yet I still get this error on 0.7.5. Any chance for a new release?

[ryankennedyio]

As above -- Python 3.4 and on Locust 0.7.5

[MrLokans]

Same issue occurs on Python 3.5 in the virtual environment.

[PrithiviRajG]

Still Getting the same error as @richardasaurus mentioned in the previous comment, when I use Locust with python 3.4.

I installed locust by running pip install locustio command

@richardasaurus How to install master branch?

[PrithiviRajG]

@richardasaurus I am not able to find requirements.txt in python34 folder in C drive..
where can I find it?

I tried to install with pip install git+git://github.com/locustio/locust.git@master#egg=locustio but I am still getting the same error

[PrithiviRajG]

Great! It's working now after deleting the locust folder already created and ran pip install git+git://github.com/locustio/locust.git@master#egg=locustio

Thanks

[simonamdev]

Just discovered Locust, looking forward to using it, however this Issue is still relevant - can we get a new PyPi release please? :)

Thanks and merry _insert holiday name_!

[AilisObrian]

Same error happened with Python 3.5.2 (virtualenv) and locust 0.7.5.

[sunnytambi]

Suggestion given by @PrithiviRajG worked for me.
I ran this first
pip uninstall locustio
then ran this
pip install git+git://github.com/locustio/locust.git@master#egg=locustio
In the end, in order to check if it is compiling and working
locust -f locustfile.py

0.8 should be released soon. Until then pip install locustio==0.8a2 should work.

[jruizaranguren]

pip install locustio==0.8a2 worked for me.

[liusong1999]

pip install locustio==0.8a2 worked for me too.

[luoziluojun]

pip install locustio==0.8a2 worked for me too

[eddscode]

Confirmed pip install locustio ==0.8a2 worked for me too.

[cgoldberg]

redundant "me too" comments on closed issues aren't very useful.

[baynes]

@heyman In Feb you said "0.8 should be released soon" - but pip still installs 0.7.5 by default and it is now July. Please can you clarify what you mean by "soon"

[cgoldberg]

@baynes: I'd also like to get the new release out, and hopefully we can get it uploaded to PyPI sooner than later. However, "soon" is subjective, and may not necessarily point to a particular point in time ¯\_(ツ)_/¯

In the meantime, you can pip install directly from git.

[charleshu44]

pip install locustio==0.8a2 worked for me too.

[Naughtron]

Has this issue been addressed? I am running a virtual env with Python 3.6 and

locustio==0.7.5
pyzmq==16.0.2
(locust_py_3)$ python
Python 3.6.2 (default, Jul 17 2017, 16:44:45)

when I attempt to run a script the following error occurs:

(locust_py_3) $ locust -f testmctest.py
Traceback (most recent call last):
  File "/Users/python_code/locust_py_3/bin/locust", line 7, in <module>

[aldenpeterson-wf]

@Naughtron have you read through any of the thread where about 10 people posted the same solution as resolving the problem?

[zjdataa]
