• Clone into ~/.vim:

  git clone https://github.com/fvisin/vim.git ~/.vim
  

• Install vundle:

  git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
  

• Open vim and run

  :PluginInstall
  

  to install the plugins

• Install python flake8 or any other syntax checker allowed by syntastic

  Troublechecking:

  • installing flake8 with pip on a system with flake8 installed as system package can cause problems. In that case,

    pip uninstall flake8
    sudo apt-get install python-flake8  --reinstall
    

  • The pylint or flake8 binaries might use as a shebang the python binary that was available during installation (e.g., some conda path, if installed from a conda environment) that might not work when the environment is not active. Try replacing it with #!/usr/bin/python if the spellcheck doesn't work.
  • pylint can interfere with flake8 sometimes. If this is the case, try reinstalling or uninstalling it.
  • More generally, running :SyntasticInfo can provide some insight on the syntax checkers errors.

• Install YouCompleteMe by running ./install.py --clang-completer in the .bundle/YouCompleteMe directory

• Note: DO NOT install jedi as a system package. If you have it as system package, remove it.
