ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin19]
2.7.1 for rbenv versions 2.6.3 with ruby -v It has become.
I want to use 2.7.1 for joint development.
This seems to be a mistake in the environment variable (PATH). From here, knowledge of UNIX commands is required, so it is recommended to study with dot installation. ↓ https://dotinstall.com/lessons/basic_unix_v2
Let's see from which path ruby is called.
asatokensei@MacBook-Air memopy % which ruby
/usr/bin/ruby
It seems that this path uses ruby, which is included by default in MacOS, instead of ruby entered in rbenv.
Path when ruby of rbenv is called ↓
$ which ruby
/Users/username/.rbenv/shims/ruby
It seems that it should be like the above.
When I check the path, ...
asatokensei@MacBook-Air memopy % echo $PATH
/usr/local/opt/[email protected]/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
You can see that /Users/username/.rbenv/shims/ruby is not included. → In other words, ruby of rbenv is not called.
Since ruby in /Users/username/.rbenv/shims/ruby should be called preferentially, ~ / .bashrc, ~ / .zshrc so that this path comes to the beginning of the environment variable (PATH) Set to etc.
asatokensei@MacBook-Air memopy % rbenv init
# Load rbenv automatically by appending
# the following to ~/.zshrc:
eval "$(rbenv init -)"
Edit ~ / .zshrc.
asatokensei@MacBook-Air memopy % vi ~/.zshrc
When this command is depressed,
export PATH="/usr/local/opt/[email protected]/bin:$PATH"
~
~
~
~
~
~
~
~
~
"~/.zshrc" 3L, 73C
The screen looks like this.
Edit by pressing the i key of insert.
eval "$(rbenv init -)"
Enter a sentence of ↑. You can save it with: wq and exit.
Command that reflects the settings you just made ↓
asatokensei@MacBook-Air memopy % source ~/.zshrc
This should have been reflected, so check it.
asatokensei@MacBook-Air memopy % ruby -v
ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-darwin19]
asatokensei@MacBook-Air memopy % which ruby
/Users/asatokensei/.rbenv/shims/ruby
asatokensei@MacBook-Air memopy % echo $PATH
/Users/asatokensei/.rbenv/shims:/usr/local/opt/[email protected]/bin:/usr/local/opt/[email protected]/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
It is 2.7.1 properly, and the path is correct.
asatokensei@MacBook-Air memopy % rbenv versions
system
2.6.6
2.7.0
* 2.7.1 (set by /Users/asatokensei/.rbenv/version)
asatokensei@MacBook-Air memopy % ruby -v
ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-darwin19]
This is OK! !! !!
