5,261 PointsI can't use Coverage in my workspace
I tried to use Coverage but I got the following error :
treehouse:~/workspace/dice$ coverage run tests.py
-bash: /home/treehouse/.local/bin/coverage: /usr/local/pyenv/versions/3.4.1/bin/python3.4: bad interpreter: No such file or directory
Notes :
I added the following to tests.py : if name == 'main': unittest.main()
I also tried to install Coverage on my workspace : treehouse:~/workspace/dice$ pip install coverage
Requirement already satisfied (use --upgrade to upgrade): coverage in /usr/local/pyenv/versions/3.5.0/lib/python3.5/site-packages
pyenv: cannot rehash: /usr/local/pyenv/shims isn't writable
Is there anything I didn't do correctly?

It appears that the environment has changed (Python is now 3.5) within the workspaces but the coverage scripts have not been updated (expects Python 3.4.1). I was able to hack this workaround in the workspaces:
# Change to dice directory
treehouse:~/workspace$ cd dice
# Explore dir
treehouse:~/workspace/dice$ ls
__pycache__ dice.py tests.py
# Try to run 'coverage'
treehouse:~/workspace/dice$ coverage tests.py
-bash: /home/treehouse/.local/bin/coverage: /usr/local/pyenv/versions/3.4.1/
bin/python3.4: bad interpreter: No such file or directory
# Fails! Time to debug....
# Where is coverage
treehouse:~/workspace/dice$ which coverage
~/.local/bin/coverage
# What is the first line of file
treehouse:~/workspace/dice$ head -1 `!!`
head -1 `which coverage`
#!/usr/local/pyenv/versions/3.4.1/bin/python3.4
# Coverage expects Python 3.4.1. Let's see what's in the workspace
treehouse:~/workspace/dice$ ls /usr/local/pyenv/versions
3.5.0
treehouse:~/workspace/dice$ ls /usr/local/pyenv/versions/3.5.0/bin/python3.5
/usr/local/pyenv/versions/3.5.0/bin/python3.5
# Need to change the `coverage` script to point to this version.
# pushd directory to 'coverage' dir
treehouse:~/workspace/dice$ pushd ~/.local/bin/
~/.local/bin ~/workspace/dice
# make a back up of coverage
treehouse:~/.local/bin$ cp coverage{,.back}
treehouse:~/.local/bin$ ls
coverage coverage-3.4 coverage.back coverage3
# Edit file to change first line from:
#!/usr/local/pyenv/versions/3.4.1/bin/python3.4
# to:
#!/usr/local/pyenv/versions/3.5.0/bin/python3.5
treehouse:~/.local/bin$ vi coverage
# Verify change
treehouse:~/.local/bin$ head -1 coverage
#!/usr/local/pyenv/versions/3.5.0/bin/python3.5
# Change back to dice directory
treehouse:~/workspace/dice$ popd

Treehouse Guest TeacherHmm. Good catch. I'll send this along to our Workspaces team. In the meantime, though, couldn't you do pip install coverage or maybe pip install --upgrade coverage?
Chris Freeman
Treehouse Moderator 68,457 PointsThe --upgrade appears to do the trick:
treehouse:~/workspace$ pip install --upgrade coverage

5,908 PointsHi all. This stills seems to be a problem. I encountered the problem as described by the OP. I initially attempted to pip upgrade then attempted Chris Freeman's workaround, I still got the original error. I then attempted to pip upgrade again, no luck. Let me know if you need more info.
Chris Freeman
Treehouse Moderator 68,457 PointsIn your workspace can you run the following commands:
treehouse:~/workspace$ head -1 ~/.local/bin/coverage
#!/usr/local/pyenv/versions/3.5.0/bin/python3.5
treehouse:~/workspace$ python --version
Python 3.5.0
And post your results? Thanks.
Theo Lekkas
5,908 PointsApparently the .local dir is empty
treehouse:~/workspace$ head -1 ~/.local/bin/coverage
head: cannot open ‘/home/treehouse/.local/bin/coverage’ for reading: No such file or directory
treehouse:~/workspace$ ls ~/.local/
treehouse:~/workspace$
Chris Freeman
Treehouse Moderator 68,457 PointsSorry. They seem to have rearranged things in newer workspaces since the last time I dug into an issue similar to this.
Are you getting the exact same error message as the OP? Can you post the error you see?
Chris Freeman
Treehouse Moderator 68,457 PointsIn the newer Workspace versions, coverage is in a new location.
treehouse:~/workspace$ head -1 /usr/local/pyenv/versions/3.5.0/bin/coverage
#!/usr/local/pyenv/versions/3.5.0/bin/python3.5
treehouse:~/workspace$ coverage --version
Coverage.py, version 4.0.3.
Documentation at https://coverage.readthedocs.org
You may need to create a new Workspace to get the correct environment.

7,174 Points@Theo Lekkas: my .local directory wasn't empty.
I followed the instructions above, first I issued the following command: pip install --upgrade coverage
After that I edited the coverage file like Chris suggested but then I got the following error when running the command: coverage run tests.py

I replaced the coverage version from 3.7.1 to 4.0.3 in the coverage file ran command again and it was fixed. Didn't see any mention of this last part so thought I'd share it.

5,908 PointsChris Freeman , yes it's the same error:
treehouse:~/workspace/dice$ coverage run tests.py
bash: /home/treehouse/.local/bin/coverage: /usr/local/pyenv/versions/3.4.1/bin/python3.5: bad interpreter: No such file or directory
Chris Freeman
Treehouse Moderator 68,457 PointsHi Theo, It looks like the Workspaces using .local/bin are out of date. Please try to create a new Workspace. The version of coverage and it's referenced Python should be:
treehouse:~/workspace$ head -1 /usr/local/pyenv/versions/3.5.0/bin/coverage
#!/usr/local/pyenv/versions/3.5.0/bin/python3.5
treehouse:~/workspace$ coverage --version
Coverage.py, version 4.0.3.

9,049 PointsChris Freeman, I'm getting the exact same error as OP and Theo.
ETA: this is what I get when I run the commands you suggested--
treehouse:/~workspace$ head -1 ~/.local/bin/coverage
#!/usr/local/pyenv/versions/3.4.1/bin/python3.4
treehouse:/~workspace$ python --version
Python 3.5.0
When I try to update coverage, it says it's already up-to-date:
coverage in /usr/local/pyenv/versions/3.5.0/lib/python3.5/site-packages
Chris Freeman
Treehouse Moderator 68,457 PointsHi Ellen, The Workspace environment seems to have changed relative to the versions of installed programs. Please try to create a new Workspace. coverage should be:
treehouse:~/workspace$ head -1 /usr/local/pyenv/versions/3.5.0/bin/coverage
#!/usr/local/pyenv/versions/3.5.0/bin/python3.5
treehouse:~/workspace$ coverage --version

Treehouse Moderator 68,457 PointsThere are some reporting this issue is back. Here is yet another solution: (copying answer from here)
There may be an workspaces environment error. The issue is there are two
coverageexecutables. In the older workspaces the directory~/.local/binis ahead of the/usr/local/pyenv/shims. The version in the~/.local/binis old and can be removed.To create a workaround:
