Ruby irbrc_history系统范围的。如何使它本地化?

I installed ruby on Ubuntu for system-wide use. The .irbrc_history file is created in a system directory rather than the user's home directory. This causes an access error when the file is owned by someone else. Here's the error besides a bunch more that I think is irrelevant:

我在Ubuntu上安装了ruby以供全系统使用。irbrc_history文件是在系统目录中创建的，而不是用户的主目录。当文件被其他人拥有时，这会导致访问错误。除了很多我认为不相关的错误之外

irb
/usr/local/rvm/rubies/ruby-2.4.1/lib/ruby/2.4.0/irb/ext/save-history.rb:75:in `initialize': Permission denied @ rb_sysopen - /usr/local/rvm/rubies/ruby-2.4.1/.irbrc_history (Errno::EACCES)

Deleting the history file resolves the error.

删除历史文件可以解决错误。

I tried adding environment variables and history initialization code to what I think is the system .irbrc file, but to no avail.

我尝试将环境变量和历史初始化代码添加到我认为的系统.irbrc文件中，但是没有效果。

What is the sequence of initialization files being executed that impact this history file? How can I change the location of the history file?

正在执行的初始化文件的顺序对这个历史文件有什么影响?如何更改历史文件的位置?

#1

Create, or edit your ~/.irbrc file to include:

创建或编辑您的~/。irbrc文件包括:

require 'irb/ext/save-history'
IRB.conf[:SAVE_HISTORY] = 200
IRB.conf[:HISTORY_FILE] = "#{ENV['HOME']}/.irb-history"

Do you happen to use RVM?

你会使用RVM吗?

rvm 1.29.3 (current stable) has a bug where IRB history gets saved in the RUBY_HOME instead of HOME.

rvm 1.29.3(当前的稳定)有一个bug, IRB的历史可以在RUBY_HOME而不是HOME保存。

Here's a fix:

这里有一个解决办法:

rvm get head
rvm reinstall 2.4.1

#3

Create the file in your home directory: touch ~/.irbrc_history.

在主目录中创建文件:touch ~/.irbrc_history。

Or copy it from the system path to your home directory: cp /path/of/system/.irbrc_history ~/.irbrc_history

或从系统路径复制到您的主目录:cp /path/of/system/。irbrc_history ~ / .irbrc_history

Note that you should change /path/of/system/ to whatever you have on your system.

注意，您应该更改/path/of/system/到您的系统上的任何内容。

Once the file is in your home directory (given by ~) then it will run when your user runs irb

一旦文件在您的主目录中(由~给出)，那么当您的用户运行irb时它将运行
