我檢查了各種 .zsh 配置以了解那里是否發生了某些事情，并且我已經2.7.6使用.zsh 重新安裝了一個新的 Ruby asdf。
我手動檢查了這些檔案，看看是否有問題
- .zshenv
- .zprofile
- .zshrc

uj5u.com熱心網友回復：
bundle install沒有運行兩次。執行第二次提取的是內部捆綁器邏輯。
# Gemfile
source "https://rubygems.org"
gem "guard-bundler"
例如，使用 bundler v2.2.6上面的Gemfile將使 bundler 運行兩個 fetch 請求。
Fetching gem metadata from https://rubygems.org/..............
Fetching gem metadata from https://rubygems.org/.
第二個請求來自雙重檢查邏輯：
https://github.com/rubygems/rubygems/blob/bundler-v2.2.6/bundler/lib/bundler/source/rubygems.rb#L261
令人驚訝的是，第二次獲取是對bundler gem 本身的雙重檢查。此拉取請求在v2.2.7中修復了該問題。
升級到 bundler v2.2.7只會發出一個請求。但是，隨著Gemfile中的 gem越來越多，捆綁器的檢查將越來越多。我假設更高版本也有更多的性能/邏輯改進。
--verbose您可以通過使用選項了解為什么 bundler 正在運行第二次提取：
$ bundle update --verbose
