@kissgyorgy : did you find a fix for this?

kissgyorgy · 2016-10-05T21:00:29Z

Not yet. 😞

marienz · 2016-10-06T11:51:22Z

Do you by any chance have pyenv installed, and does pyenv which ipython return the path to a working ipython?

Glancing at the code, I think spacemacs/python-setup-shell should be using the return value from (spacemacs/pyenv-executable-find "ipython") to run ipython, instead of assuming that if that call returns non-nil it can run (shell-command-to-string "ipython --version"). spacemacs/pyenv-executable-find may have found an ipython that is not on $PATH.

@marienz : Yes, I have pyenv and it does return a valid path:

➜  jramapuram@gauss ~ pyenv which ipython
/Users/jramapuram/.virtualenvs/default/bin/ipython

kissgyorgy · 2016-10-06T12:01:20Z

I have it too:

$ pyenv which ipython
/usr/local/var/pyenv/versions/2.7.11/bin/ipython

same problem here but only occurs when I starts spacemacs from terminal.

os: archlinux 4.7.6 emacs: 25.1 spacemacs 0.200.1 ipython: valid path.

geekplux · 2016-10-17T18:03:47Z

same problem.

OS: mac OS
emacs: 25.1
spacemacs: 0.200.1

Managed to fix it by setting global python to 3.5.2 - pyenv global 3.5.2 and then pip install ipython.

jsevo · 2016-10-19T23:54:40Z

@evindor not fixing it for me :/

Mac OSX 10.10.5
Spacemacs: 0.200.3
Emacs 25.1.1

kissgyorgy · 2016-10-19T23:57:20Z

Not fixed for me either. I have ipython installed anyway.

cranehuang · 2016-11-26T05:28:34Z

@jsevo @kissgyorgy Check the PATH variable in Emacs and in Terminal shell, it may be different. I use pyenv and zsh, and I find that PATH in emacs doesn't contain the pyenv path config, but PATH in shell does. To solve this, suppose you use zsh, you can create a ".zshenv" file, and put the PATH config in it, it should work. I found this solution from the Spacemacs'FAQ part. See the picture:

jbyler · 2017-09-14T20:59:17Z

I had pyenv installed, but don't use it. pyenv which ipython gave me this error:

pyenv: version `' is not installed (set by /Users/.../.pyenv/version)

Since I don't use it, I just did brew unlink pyenv and the Spacemacs startup error went away.

braham-snyder · 2018-03-12T03:44:20Z

FWIW: I don't use pyenv, nor did I have it installed. ipython --version from my terminal printed:

Failed to execute process '/usr/local/bin/ipython'. Reason:
The file '/usr/local/bin/ipython' specified the interpreter '/usr/local/opt/python/bin/python2.7', which is not an executable command.

pip install --upgrade ipython updated ipython, which seems to have done the trick.

jarandaf · 2018-09-12T07:27:10Z

I was using zsh shell with pyenv and to make it work had to configure the following:

(setenv "SHELL" "/bin/zsh")
(setq shell-file-name "/bin/zsh")

bersace · 2018-12-12T15:19:50Z

Hi, I hit this bug when upgraded to Debian Buster, using emacs daemon, but only when reloading with SPC f e R. I don't want ipython. pyenv shims directory is in my PATH from my .profile that way : https://gitlab.com/bersace/dotfiles/blob/master/files/.profile#L50-54 . Any clue on this ?

bersace · 2018-12-12T15:21:54Z

I have this issue with both no ipython, ipython installed in ~/.local/bin or in /usr/bin with debian package.

bersace · 2018-12-12T15:32:03Z

Hi all, i may have found the root of the issue. .spacemacs.env was not up to date, and overrides pyenv and path with wrongs values. Renaming .spacemacs.env fixed the bug. Does it help anyone too ?

or · 2019-07-05T06:32:49Z

I ran into this as well. I ran ielm (SPC SPC ielm), then

ELISP> (spacemacs/pyenv-executable-find "ipython")
"pyenv: version `3.7.0' is not installed (set by PYENV_VERSION environment variable)"

Then found PYENV_VERSION=3.7.0 in ~/.spacemacs.env and removed it. I suspect a similar thing could happen if there were an old .python-version lurking around somewhere.

This could report a more useful error message. Might be small enough to practice a bit of elisp, so I'll try to add it. :)

This fixed this issue for me. Thanks @braham-snyder 😄
