react native install cocoapods 附带搭建 rn 0.72 的完整过程使用如下命令,初始化

使用如下命令,初始化 react native 项目

npx react-native@0.72 init rndemo_02 --version 0.72.5

一定会出现如下类似的错误,

✖ Installing CocoaPods dependencies (this may take a few minutes)

**error** NameError: uninitialized constant ActiveSupport::LoggerThreadSafeLevel::Logger


✖ Installing CocoaPods dependencies (this may take a few minutes)

**error** Looks like your iOS environment is not properly set. Please go to https://reactnative.dev/docs/environment-setup?os=macos&platform=android and follow the React Native CLI QuickStart guide for macOS and iOS.

参考了 stackoverflow 里面的部分建议，手动重新安装 cocoapods

参考了解决CocoaPods安装卡住反应慢或失败里面介绍的命令, 在网上找到个参数，可以查看安装进度，在最后加上-V

# 注意V是大写 

sudo gem install cocoapods -V

经历了非常漫长的时间，得到了如下结果。

ERROR:  Error installing cocoapods:

The last version of securerandom (>= 0.3) to support your Ruby & RubyGems was 0.3.2. Try installing it with `gem install securerandom -v 0.3.2` and then running the current command again

securerandom requires Ruby version >= 3.1.0. The current ruby version is 2.6.10.210

意思是说 ruby 版本太低了，我的系统是 Apple m3 pro macOS 15.3.2 (24D81) 。系统自带 ruby 版本 2.6.10.210 。

所以手动安装最新版 ruby, ruby@3.3

brew install ruby@3.3

安装完成后有如下提示，

==> ruby@3.3
By default, binaries installed by gem will be placed into:
  /opt/homebrew/lib/ruby/gems/3.3.0/bin

You may want to add this to your PATH.

ruby@3.3 is keg-only, which means it was not symlinked into /opt/homebrew,
because this is an alternate version of another formula.

If you need to have ruby@3.3 first in your PATH, run:
  echo 'export PATH="/opt/homebrew/opt/ruby@3.3/bin:$PATH"' >> ~/.zshrc

For compilers to find ruby@3.3 you may need to set:
  export LDFLAGS="-L/opt/homebrew/opt/ruby@3.3/lib"
  export CPPFLAGS="-I/opt/homebrew/opt/ruby@3.3/include"

执行这一条终端命令，使 ruby@3.3 为优先使用的版本

echo 'export PATH="/opt/homebrew/opt/ruby@3.3/bin:$PATH"' >> ~/.zshrc

查看 gem 源地址

查看替换后的源地址

➜  ~ gem sources -l
*** CURRENT SOURCES ***

https://rubygems.org/

上面的经历可知官方源安装速度慢到让人崩溃，替换源是最简单的方法

# 替换源
$ gem sources --add https://gems.ruby-china.com/ --remove https://rubygems.org/
# 查看替换后的源地址
$ gem sources -l
https://gems.ruby-china.com
# 确保只有 gems.ruby-china.com

实操

➜  ~ gem sources --add https://gems.ruby-china.com/ --remove https://rubygems.org/

https://gems.ruby-china.com/ added to sources
https://rubygems.org/ removed from sources
➜  ~ 
➜  ~ gem sources -l
*** CURRENT SOURCES ***

https://gems.ruby-china.com/

不放心 gem 版本，再看一眼。

➜  ~ sudo gem -v
Password:
3.6.3
➜  ~ gem -v
3.6.3

再次回到开头，感受一下光速安装 cocoapods

sudo gem install cocoapods -V

再次初始化 react native 项目

npx react-native@0.72 init rndemo_01 --version 0.72.5

其中，前面 4 个带对号的不走大概在 2 分钟左右完成，估计有 npm 缓存的原因，最后一个 Installing CocoaPods dependencies 执行了 3分钟以上，然后失败

上面意思安装 boost sum 验证不一致.

当我记录这一过程时，2025年03月22日17:39:11，此时 react native 官网最新版本是 0.78, 我为了学习 openharmony 大神，涂纯的课， OpenHarmony 应用开发之ReactNative入门的视频，里面用的是 0.72.5 版

ok, google 一下怎么解决，

stackoverflow.com/questions/7… github.com/boostorg/bo…

看 stack overflow 里面的记录似乎 react native 0.73 之前的版本都有一定的概率遇到这个问题。

首先，找到 react native 项目的这个目录 node_modules/react-native/third-party-podspecs

注意这里

替换 https://boostorg.jfrog.io/artifactory/main/release/1.76.0/source/boost_1_76_0.tar.bz2 为 https://archives.boost.io/release/1.76.0/source/boost_1_76_0.tar.bz2 注意，这两个地址，除了域名不同，路径也不同域名: 一个是 https://boostorg.jfrog.io 另一个是 https://archives.boost.io 路径: 一个是 artifactory/main/release/1.76.0/source/boost_1_76_0.tar.bz2 另一个是 /release/1.76.0/source/boost_1_76_0.tar.bz2 注意，路径里面 release 路径之前的差异，如果你遇到的问题里面的 boost 版本号和我的不一样，只需要注意路径的不同就行了。

修改后为

然后，回到 ios 目录，执行如下命令，应该就已经解决了 boost 的问题，所有的问题应该都解决了。

cd ios & pod install

回到项目根目录, 运行一下向项目。

cd ..
npm run start

当我觉得应该没有问题了的时候，问题又来了，

info Opening the app on iOS...
info Found Xcode workspace "rndemo_02.xcworkspace"
node:events:496
      throw er; // Unhandled 'error' event
      ^

查到这里 https://stackoverflow.com/questions/58675179/error-emfile-too-many-open-files-react-native-cli 提到 watchman watch-del-all

➜  rndemo_02 watchman watch-del-all 
{
    "version": "2025.03.10.00",
    "roots": []
}

然后再次

npm run start

此时打开了 ios 模拟器，然鹅， app 并没有在模拟器里面启动。终端里面的输出好像在如下画面冻住了，没有办法了，重启电脑看看。

 ➜ Explicit dependency on target 'React-RCTActionSheet' in project 'Pods'
        ➜ Explicit dependency on target 'React-RCTAnimation' in project 'Pods'

        ➜ Explicit dependency on target 'React-RCTBlob' in project 'Pods'
        ➜ Explicit depe

过程进行到这里，感觉自己已经崩溃了，0.72.5 卡死在弹出来的终端那里，

就连尝试 0.78.1 也是 ios 代码在xcode 里面一堆的错误，再次放弃。

有人写了这样的文字,,,,, 其实无用

下面是一些无价值的文字，

解决方法

执行 watchman watch-del-all
执行 rm node_modules 删掉依赖
重新装依赖，注意不要用npm，一定要用yarn install
执行 rm /tmp/metro-*
执行 npm run android 完美解决。

不要用`npm install` 个人感觉 `rn` 对 `npm` 不太友好，请使用`yarn` 安装你需要的模块

然鹅没有用

上面是一些无价值的文字

这里看到里一个回复 github.com/facebook/re…

update 2025年03月23日16:10:46 因为是 react native 0.72，对应的nodejs 请使用 v20.19.0 v20 lts. 版本，我使用的 v18 版本会卡主。

这些是一些可参考的基础知识

cd ios to navigate to the ios folder.
bundle install to install Bundler
bundle exec pod install to install the iOS dependencies managed by CocoaPods.

github.com/facebook/re…

Navigate to your project folder
Run yarn install to make sure to pull in all the files required, especially if you updated the project
Cd-ing into the ios folder
run bundle exec pod deintegrate to cleanup the cocoapods and the projects.
run bundle exec pod install to make sure the new scripts run properly.

下载 fmt 会 github 拉取代码

# 开启 git 代理：
git config --global http.proxy 'socks5://127.0.0.1:7890'
git config --global https.proxy 'socks5://127.0.0.1:7890'

# 取消 git 代理
git config --global --unset http.proxy
git config --global --unset https.proxy

到这一步，应该可以安装完所有的依赖，但是当你运行 yarn ios 想要启动项目，你一定会遇到这个问题，

此时你的内心是崩溃的，从数出来看，它让你用 xcode 打开项目，在项目根目录 xed -b ios ios 对应项目根目录下的 ios 目录，这个命令会启动 xcode 打开 ios 对于第一次学习 react native 且无项目经验的人来说，进入 xcode ，这里做了两件事，登录 apple id，和修改包名
