Couldn't source environment when use grep with color output

[ertaquo]

Hello. I had a problem with gvm (latest version at this moment) when I tried to install any go version. It installs, but cannot be used:

$ gvm use go1.4
ERROR: Couldn't source environment

I found it's because line 20 in scripts/env/use:

  fuzzy_match=$($LS_PATH "$GVM_ROOT/gos" | $SORT_PATH | $GREP_PATH "$VERSION" | $HEAD_PATH -n 1 | $GREP_PATH "$VERSION")

It finds go version via ls and grep. But when grep used with color output (--color=always or something like that) this command takes entire grep output, with ANSI color codes. And so...

ls: /Users/ertaquo/.gvm/environments/\033[01;31m\033[K\033[01;31m\033[Kgo1.4\033[m\033[K\033[m\033[K: No such file or directory

I fixed it by modifying this line:

  fuzzy_match=$($LS_PATH "$GVM_ROOT/gos" | $SORT_PATH | $GREP_PATH --color=never "$VERSION" | $HEAD_PATH -n 1 | $GREP_PATH --color=never "$VERSION")

But it's just nail and I sure it should be fixed in more properly way :)

$ cat ~/.bash_profile
export CLICOLOR=1
export LSCOLORS=ExFxBxDxCxegedabagacad
alias ls='ls -GFh'

export GREP_OPTIONS='--color=always'

I fixed this by simply changing fuzzy_match to equal $1 - so as long as you've installed the right version, you're good.

this problem also shows up with function gvm_export_path in scripts/function/gvm_export_path:

  1  #!/usr/bin/env bash
  2  function gvm_export_path() {
  3     export PATH="$GVM_ROOT/bin:$(echo "$PATH" | tr ":" "\n" | "$GREP_PATH" -v '^$' | egrep -v "$GVM_ROOT/(pkgsets|gos|bin)" | tr "\n" ":" | sed 's/:*$//')"
  4     export GVM_PATH_BACKUP="$PATH"
  5  }

In line 3, there is an egrep command. In my case, I have previously aliased egrep = 'egrep --color=always' in my .bashrc script, and it breaks this function above.

Since egrep is deprecated, and grep -E is preferred, the solution here is to change the egrep on line 3 above to "$GREP_PATH" -E
