 Posted: Sat Nov 12, 2022 3:22 pm Post subject: Can't activate Python virtual enviroment due to syntax error |
 |
|
For some reason I get syntax error when I try to activate Python virtual environment.
| Code: | python3 -m venv env
source env/bin/activate
|
Produces following error:
| Code: | bash: env/bin/activate: line 36: syntax error near unexpected token `}'
bash: env/bin/activate: line 36: `}'
|
The sourced file has the following contents:
| Code: | # This file must be used with "source bin/activate" *from bash*
# you cannot run it directly
deactivate () {
# reset old environment variables
if [ -n "${_OLD_VIRTUAL_PATH:-}" ] ; then
PATH="${_OLD_VIRTUAL_PATH:-}"
export PATH
unset _OLD_VIRTUAL_PATH
fi
if [ -n "${_OLD_VIRTUAL_PYTHONHOME:-}" ] ; then
PYTHONHOME="${_OLD_VIRTUAL_PYTHONHOME:-}"
export PYTHONHOME
unset _OLD_VIRTUAL_PYTHONHOME
fi
# This should detect bash and zsh, which have a hash command that must
# be called to get it to forget past commands. Without forgetting
# past commands the $PATH changes we made may not be respected
if [ -n "${BASH:-}" -o -n "${ZSH_VERSION:-}" ] ; then
hash -r 2> /dev/null
fi
if [ -n "${_OLD_VIRTUAL_PS1:-}" ] ; then
PS1="${_OLD_VIRTUAL_PS1:-}"
export PS1
unset _OLD_VIRTUAL_PS1
fi
unset VIRTUAL_ENV
unset VIRTUAL_ENV_PROMPT
if [ ! "${1:-}" = "nondestructive" ] ; then
# Self destruct!
unset -f deactivate
fi
}
# unset irrelevant variables
deactivate nondestructive
VIRTUAL_ENV="/home/msj/testtti/env"
export VIRTUAL_ENV
_OLD_VIRTUAL_PATH="$PATH"
PATH="$VIRTUAL_ENV/bin:$PATH"
export PATH
# unset PYTHONHOME if set
# this will fail if PYTHONHOME is set to the empty string (which is bad anyway)
# could use `if (set -u; : $PYTHONHOME) ;` in bash
if [ -n "${PYTHONHOME:-}" ] ; then
_OLD_VIRTUAL_PYTHONHOME="${PYTHONHOME:-}"
unset PYTHONHOME
fi
if [ -z "${VIRTUAL_ENV_DISABLE_PROMPT:-}" ] ; then
_OLD_VIRTUAL_PS1="${PS1:-}"
PS1="(env) ${PS1:-}"
export PS1
VIRTUAL_ENV_PROMPT="(env) "
export VIRTUAL_ENV_PROMPT
fi
# This should detect bash and zsh, which have a hash command that must
# be called to get it to forget past commands. Without forgetting
# past commands the $PATH changes we made may not be respected
if [ -n "${BASH:-}" -o -n "${ZSH_VERSION:-}" ] ; then
hash -r 2> /dev/null
fi

Is this something to do with env variables since the syntax itself should be fine? |

No, environment variables should not be able to cause that problem.
That script is well-formed for me. In the shell where you received the error message, what is the output of /proc/self/exe --version? |

Hmm, I see..
The output was:

| That looks reasonable. Your shell is fairly current. Are there any carriage returns in the script? Those could have been lost when pasting it onto the forum, allowing it to work as posted, but not as stored on your disk. If you copy the script shown in your post into a new script file, and source that, does it also fail? Have you tried trimming down the script to find the minimal version that still fails? |

No, I got the same error when copy-pasting the contents. I have other machine that has pretty identical Gentoo install and it doesn't have same kind of a problem.
I also tried to trim down the script but if it had anything else than variable declarations I got "unexpected end of file"-error. |

Since the script works for me, and works for one of your other Gentoo installations, that suggests an obscure problem with the shell on the bad system. Since I cannot reproduce the problem as posted, I cannot directly debug this. There are plenty of ways to reduce the script that will make it invalid. The goal is to find the one which is closest to the version shown, but is accepted even on the bad system.
What is the output of emerge --info app-shells/bash on the bad system? |

That would indicate that the issue isn't with the script or bash parsing it, but the "source" command doing something unexpected. What happens if you run
(should do the same as "source") |

Yeah, makes sense.
It produces the same error about the syntax as the source command |

Ok, that makes it unlikely that somehow accidentally "source" got modified/redirected.
Well, as you have another system that works the most obvious thing to do is to check what differences there are between the systems. Mainly in any bash-related files within /etc/ and $HOME.
Or try to create a new user account and see if the problem can be reproduced there (if not the issue is with the bash configuration in your original account).
Pretty weird issue, but wouldn't be surprised if it has a facepalm solution. |

| Your suggestion about facepalm solution made a light bulb turn on in my head. Disabled .bashrc and it works perfectly now. I'll debug later what was the actual cause for this but at least the problem got solved. Thanks to everyone helping with this one! |

| If you share the broken .bashrc, someone might be able to point you in the right direction. |

The contents of the broken .bashrc are:
| Code: |
# /etc/skel/.bashrc
#
# This file is sourced by all *interactive* bash shells on startup,
# including some apparently interactive shells such as scp and rcp
# that can't tolerate any output. So make sure this doesn't display
# anything or bad things will happen !
# Test for an interactive shell. There is no need to set anything
# past this point for scp and rcp, and it's important to refrain from
# outputting anything in those cases.
if [[ $- != *i* ]] ; then
# Shell is non-interactive. Be done now!
return
fi
if [ -e $HOME/.bash_aliases ]; then
source $HOME/.bash_aliases
fi
########################
# #
# ENV VARS #
# #
########################
EDITOR='/usr/bin/vim'
PATH="$HOME/.local/bin:$PATH"
export PATH="$HOME/.local/share/go/bin:$PATH"

| All that looks relatively safe (though unchecked $PATH concatenation is technically wrong) - but it also sources in .bash_aliases, which is not shown and could have something weird in it. |

Ah good to know. The .bash_aliases doesn't have anything special in it.
| Code: |
alias ls='ls --color=auto -lhF'
alias mutt='neomutt'
alias tp='trash-put'
alias steam='flatpak run com.valvesoftware.Steam'
alias bt='bluetoothctl'
alias halfscreen='xrandr --output DisplayPort-2 --mode 2560x1440'
alias fullscreen='xrandr --output DisplayPort-2 --mode 5120x1440'

If the .bashrc would be broken you'd have problems in all shell sessions. There is apparently just some very weird interaction going on between that and the source command used for the venv script (can't spot anything suspicious though).
Would probably still create a new account to verify that the issue is isolated to the existing account, and then transfer the content of .bashrc and .bash_aliases piece by piece to narrow down what is triggering the issue. |
