问题描述
所以我安装了fish和oh-my-fish,当我想使用rvm时出现这个错误:
So I installed fish and oh-my-fish, and when i want to use rvm I get this error:
➜ avalancha git:(services) ✗ rvm use 2.1.0 Using /home/matias/.rvm/gems/ruby-2.1.0 fish: The '$' character begins a variable name. The character '{', which directly followed a '$', is not allowed as a part of a variable name, and variable names may not be zero characters long.

(source) call of file '-', called on line 22 of file '/home/matias/.config/fish/functions/rvm.fish', in function 'rvm', called on standard input, with parameter list 'use 2.1.0' .: Error while reading file '-'有人知道是什么吗?
推荐答案我遇到了同样的问题.这是由 rvm_debug 变量的多行值引起的不兼容.我修补了该函数以通过进行一些小的更改来完全忽略此变量.
I had the same issue. It's an incompatibility caused by the multiline value of the rvm_debug variable. I patched the function to ignore this variable completely by making a small change.
打开 ~/.config/fish/functions/rvm.fish 并将第 7 行更改为:
and eval (grep '^rvm\|^[^=]*PATH\|^GEM_HOME' $env_file | grep -v '_clr=' | sed '/^[^=]*PATH/s/:/" "/g; s/^/set -xg /; s/=/ "/; s/$/" ;/; s/(//; s/)//')进入这个:
and eval (grep '^rvm\|^[^=]*PATH\|^GEM_HOME' $env_file | grep -v '_clr=' | grep -v 'rvm_debug=' | sed '/^[^=]*PATH/s/:/" "/g; s/^/set -xg /; s/=/ "/; s/$/" ;/; s/(//; s/)//')我不知道 rvm_debug 用于什么,但我的系统似乎没有它就可以工作.
I don't know what rvm_debug is being used for, but my system seems to work without it.
