rvm获取“未定义的方法” nil：nilclass＆quot＆quot在MacOS上安装Ruby
我正在尝试使用RVM在2018 Mac Mini中安装Ruby 3.0.x。我无法安装3.0.4、3.0.2、3.0.0（然后我尝试了2.7.5，只是为了查看该问题是否特定于3.0.x）。所有这些安装中的所有4个都失败了，但完全相同的错误：
ruby-3.0.4 - #post-configuration - please wait
ruby-3.0.4 - #compiling - please wait
Error running '__rvm_make -j6',
please read /Users/macmini/.rvm/log/1652638839_ruby-3.0.4/make.log
There has been an error while running make. Halting the installation.
make.log以以下几行结束，
generating encdb.h
builtin_binary.inc updated
compiling builtin.c
encdb.h updated
x86_64-darwin21-fake.rb updated
NoMethodError: undefined method `empty?' for nil:NilClass
<main> at -e:2
make: *** [.rbconfig.time] Error 1
+__rvm_make:0> return 2
我在Big Sur和Monterey 12.3.1上获得了相同的故障。
encdb.h updated
NoMethodError: undefined method `empty?' for nil:NilClass
-e at -e:2
make: *** [.rbconfig.time] Error 1
+__rvm_make:0> return 2
任何帮助将不胜感激！＆nbsp; ＆nbsp;谢谢！！！

I'm trying to install Ruby 3.0.x using rvm on a 2018 Mac mini. I couldn't install 3.0.4, 3.0.2, 3.0.0 (then I tried 2.7.5, just to see if the issue was specific to 3.0.x). All 4 of these installs failed with exactly the same error:
ruby-3.0.4 - #post-configuration - please wait
ruby-3.0.4 - #compiling - please wait
Error running '__rvm_make -j6',
please read /Users/macmini/.rvm/log/1652638839_ruby-3.0.4/make.log
There has been an error while running make. Halting the installation.
make.log ends with the following lines
generating encdb.h
builtin_binary.inc updated
compiling builtin.c
encdb.h updated
x86_64-darwin21-fake.rb updated
NoMethodError: undefined method `empty?' for nil:NilClass
<main> at -e:2
make: *** [.rbconfig.time] Error 1
+__rvm_make:0> return 2
I get this same failure on Big Sur and on Monterey 12.3.1.
There is an issue on github that has 8 people reporting what sounds like the same error between 8/10/21 and 2/24/22, with no one reporting a solution (except a suggestion of switching to rbenv). Two of these posts have lines at the end of make.log that are extremely similar to what I'm seeing:
encdb.h updated
NoMethodError: undefined method `empty?' for nil:NilClass
-e at -e:2
make: *** [.rbconfig.time] Error 1
+__rvm_make:0> return 2
Any assistance would be greatly appreciated! Thanks!!!

弄清楚了。我目前的＆amp;默认Ruby设置为Jruby-9.2.9.0。我将其设置为Ruby-2.7.6，现在3.0.4安装没有任何问题。
Figured it out. My current & default ruby was set to jruby-9.2.9.0. I set it to ruby-2.7.6 and now 3.0.4 installs without any issues.
仅安装了Jruby，必须在安装新的Crouby版本之前使用
RVM使用System。这是在Centos上。Only had JRuby installed, had to go with
rvm use systembefore installing new CRuby version. And this was on Centos.
