Question

所以我安装了鱼和哦我的鱼，当我想使用rvm时我得到了这个错误：

➜ 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. To learn more about variable expansion in fish, type 'help expand-variable'.

in function 'rvm',

    with parameter list 'use 2.1.0'

.: Error while reading file '-'

有谁知道它会是什么？

我有同样的问题。它是由rvm_debug变量的多行值引起的不兼容性。我修补了函数，通过进行一些小改动来完全忽略这个变量。

打开〜/ .config / fish / functions / rvm.fish 并从中更改第7行：

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正在使用什么，但我的系统似乎没有它。

Fish RVM使用错误
