问题描述

我已经设置了$GEM_HOME,但是gem install仍在安装到默认的~/.gem目录中.

I have $GEM_HOME set, but gem install is still installing to the default ~/.gem directory.

此rubygems问题说要删除.gemrc中的--user-install选项,但是我没有.gemrc文件.

This rubygems issue says to remove the --user-install option in .gemrc, but I don't have a .gemrc file.

如何获取gem install来兑现$GEM_HOME的值?

在这里,我首先删除~/.gem,然后显示它是自动创建的:

Here I firstly remove ~/.gem, and then show that it is automatically created:

% rm -rf ~/.gem
% find ~ -name '*gemrc*'
% # No output, so .gemrc doesn't exist
% echo $GEM_HOME
/home/ravi/.local/share/gem
% gem install neovim

推荐答案

正如Casper在评论中指出的那样,我的配置仍在某处获取--user-install.

As Casper pointed out in the comment, my configuration was still getting --user-install from somewhere.

当我的~/.gemrc不存在时,我签入/etc/gemrc并发现了以下内容:

While my ~/.gemrc didn't exist, I checked in /etc/gemrc and found the following:

# --user-install is used to install to $HOME/.gem/ by default since we want to separate
#                pacman installed gems and gem installed gems
install: --user-install

要覆盖此问题,我将其添加到了~/.gemrc:

To override this, I added to my ~/.gemrc:

install: --no-user-install

现在$GEM_HOME被尊重了.
