Running setup.sh aborts with Exception: TypeError: __cal__() takes exactly 2 arguments (1 given)

I'm attempting to install sync engine on a mint 17 box (based on ubuntu 14.04). Running setup.sh goes through for a bit and then errors out with the following message:

How can I get past this error?

I am getting the same error and I already reported here: #431

I received no answer from the devs at all.

I also have this issue. Seems to be an issue with the old installed python version and pip. As a workaround I installed the latest version of python2.7.13 from the tarball.

tar -xzf python-2.7.13.tgz
cd Python/
sudo ./configure
sudo make
sudo make install

after that run sudo ./setup.sh again and it should work fine.

Installing the latest python version did not solve my problem when running the virtual machine using vagrant.

I modified setup.sh to install the newest python, but it still fails.

[shchukax]

I tried with Python 2.7.13 and even with Python 3.4 (this doesn't work for a variety of other reasons) - to no avail. What finally did fix it for me is this:

In file /usr/local/lib/python2.7/dist-packages/packaging/requirements.py, line 59 is this one:

MARKER_EXPR = originalTextFor(MARKER_EXPR())("marker")

I changed it to

MARKER_EXPR = originalTextFor(MARKER_EXPR(""))("marker")

And that was it - everything went through after that.

@shchukax Thanks, that indeed works!

@shchukax Thanks, it works for me.

How do the nylas guys make this work? I thought vagrant was supposed to give us a 100% identical build.

@grinich can you weight in on this?

In order to fix problems with building the sync-engine, including: #427, #429, #430, #431

Here is what I add into my setup.sh:

export PYTHONPATH=/vagrant:$PYTHONPATH
echo "export PYTHONPATH=/vagrant:$PYTHONPATH" >> /etc/profile
sed -i '59s/MARKER_EXPR()/MARKER_EXPR("")/g' /usr/local/lib/python2.7/dist-packages/packaging/requirements.py

after apt-get -y install ... in line 100

and
easy_install -U pyasn1 setuptools

after pip install ... in line 180

Destroy the vagrant box and run vagrant up again, things seem to work fine for me :)

@shchukax, great solution! It worked! Many thanks!

[hmalshe]

@shchukax great fix! Thanks!

pip install setuptools==33.1.1

[porsche613]

pip install setuptools==33.1.1 or pip install --upgrade setuptools (when confirmed using a old version) are ok
