React Native 0.71.1项目Ruby相关报错及安装问题求助

问题汇总 #

1. 进入项目目录时的RVM报错 #

RVM used your Gemfile for selecting Ruby, it is all fine - Heroku does that too,
you can ignore these warnings with 'rvm rvmrc warning ignore /Users/transformhub/Desktop/rnapp/Gemfile'.
To ignore the warning for all files run 'rvm rvmrc warning ignore allGemfiles'.

Unknown ruby interpreter version (do not know how to handle): File.readFile.join__dir__,.ruby-version.strip.

2. iOS目录执行依赖安装命令报错 #

执行bundle install && RCT_NEW_ARCH_ENABLED=1 bundle exec pod install时出现：

[!] There was an error parsing Gemfile: No such file or directory @ rb_sysopen - /Users/transformhub/Desktop/rnapp/.ruby-version. Bundler cannot continue.

from /Users/transformhub/Desktop/rnapp/Gemfile:4 #

------------------------------------------- #

# You may use http://rbenv.org/ or https://rvm.io/ to install and use this version #

ruby File.read(File.join(dir, '.ruby-version')).strip

#

------------------------------------------- #

3. rbenv安装Ruby 2.7.6时编译报错 #

执行rbenv install 2.7.6出现：

readline.c:1904:37: error: use of undeclared identifier 'username_completion_function'; did you mean 'rl_username_completion_function'?
                                    rl_username_completion_function);
                                    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

readline.c:79:42: note: expanded from macro 'rl_username_completion_function'
# define rl_username_completion_function username_completion_function
                                         ^

当前环境信息 #

• Ruby版本：ruby 3.2.0 (2022-12-25 revision a528908271) [arm64-darwin22]
• PATH输出：

/Users/transformhub/.rbenv/shims:/Users/transformhub/.rbenv/shims:/Users/transformhub/.rbenv/bin:/Users/transformhub/.rbenv/shims:/opt/homebrew/opt/ruby/bin:/Users/transformhub/.gem/bin:/Users/transformhub/.pyenv/shims:/Users/transformhub/.pyenv/bin:/Users/transformhub/.pyenv/bin:/Users/transformhub/.rbenv/shims:/Users/transformhub/.rbenv/bin:/Library/Frameworks/Python.framework/Versions/3.9/bin:/opt/homebrew/bin:/opt/homebrew/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/transformhub/Desktop/flutter/bin :/usr/local/go/bin:/usr/local/share/dotnet:~/.dotnet/tools:/Library/Apple/usr/bin:/Library/Frameworks/Mono.framework/Versions/Current/Commands:/Applications/Postgres.app/Contents/Versions/latest/bin:/Users/transformhub/Library/Android/sdk/platform-tools:/Users/transformhub/Users/transformhub/Desktop/flutter/bin:/Users/transformhub/Android/Sdk/tools:/Users/transformhub/Android/Sdk/tools/bin:/Users/transformhub/Android/Sdk/platform-tools:/Library/Frameworks/Python.framework/Versions/3.9/bin:/opt/homebrew/bin:/opt/homebrew/sbin:/Users/transformhub/Desktop/flutter/bin:/Users/transformhub/.cargo/bin:/Users/transformhub/.rvm/bin

解决方案 #

1. 修复Gemfile解析错误及缺少.ruby-version文件问题 #

• 项目根目录创建.ruby-version文件，写入React Native推荐版本：

  echo "2.7.6" > /Users/transformhub/Desktop/rnapp/.ruby-version
  

• 若Gemfile读取逻辑仍有问题，可临时硬编码版本：将Gemfile第4行替换为：

  ruby "2.7.6"
  

2. 解决RVM与rbenv冲突及目录警告 #

• 移除PATH中的RVM路径，避免版本管理工具冲突：编辑~/.zshrc或~/.bashrc，删除包含~/.rvm/bin的行，然后执行：

  source ~/.zshrc # 对应你的shell配置文件
  

• 若需保留RVM，执行命令忽略Gemfile警告：

  rvm rvmrc warning ignore /Users/transformhub/Desktop/rnapp/Gemfile
  

3. 修复rbenv安装Ruby 2.7.6的readline编译错误 #

• 安装兼容的低版本readline：

  brew install readline@8.1
  

• 指定该readline版本编译安装Ruby：

  RUBY_CONFIGURE_OPTS="--with-readline-dir=$(brew --prefix readline@8.1)" rbenv install 2.7.6
  

• 切换项目使用该Ruby版本：

  cd /Users/transformhub/Desktop/rnapp
  rbenv local 2.7.6
  

4. 重新执行iOS依赖安装 #

完成上述步骤后，进入iOS目录重新执行命令：

cd /Users/transformhub/Desktop/rnapp/ios
bundle install && RCT_NEW_ARCH_ENABLED=1 bundle exec pod install
