This is the first blog entry which I write in my new home. I moved from Hoppel to Doll (#473). Hoppel is a HP ProBook 4540s, Doll is a Dell Latitude E6430.
I can confirm a subtle problem which might cause trouble when
Install your Lino developer environment: if
pip install -e atelier or
install -e lino fails because the Python headers are not installed,
then a subsequent call (after
sudo apt-get install python-dev)
does not install the missing packages. In my case I had to manually
$ pip install pycrypto ecdsa markupsafe
Here another funny problem reported by Emacs:
You are not using the same version of Elpy in Emacs Lisp compared to Python. This can cause random problems. Please do make sure to use compatible versions. Elpy Emacs Lisp version: 1.2.1 Elpy Python version....: 1.9.0
So I did:
$ pip uninstall elpy $ pip install 'elpy==1.2.1'
Later I also saw that I had to reinstall the elpy package.
And another one during sigal:
INFO: Processing /home/luc/dell1tb/cache/sigal_tmp/2014/04/27/img_6793.jpg INFO: Failed to process: IOError('decoder jpeg not available',)
Here it was stackoverflow who helped:
$ sudo apt-get install libjpeg-dev
And Emacs had another problem:
Flymake: Failed to launch syntax check process ‘flake8’ with args (…): Searching for program: no such file or directory, flake8. Flymake will be switched OFF
This was because in my custom.el I had:
which was Hoppel’s location of my virtualenvs.
