安裝參照標(biāo)準(zhǔn)：React Native中文網(wǎng)

一.安裝node(需要先安裝homebrew)

$ brew install node

1.下載過慢/失?。?/h4>

若非墻則重試很多次都下載很慢，有些依賴下載不下來，我的是node和python下載不下來提示如下：

2.解決方法

使用代理【下載工具（shadowsockets），找免費/自費ssr配置好】

方法一：打開shadowsockets復(fù)制終端代理命令，查看地址：為127.0.0.1:1087，終端輸入：（親測可用）

$ ALL_PROXY=socks5://127.0.0.1:1087 brew install node

方法二：打開shadowsockets，復(fù)制終端代理命令，粘貼到終端回車，再安裝

$ export http_proxy=http://127.0.0.1:1087;export https_proxy=http://127.0.0.1:1087;
$ brew install node

3.查看是否安裝成功

若成功則顯示版本號

$ node -v

v13.8.0

二.安裝watchman

$ brew install watchman

查看是否安裝成功

若成功則顯示版本號

$ watchman -v

4.9.0

三.安裝nrm

具體其他功能可參考nrm安裝與配置

$ npm install -g nrm

npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142
npm WARN deprecated coffee-script@1.7.1: CoffeeScript on NPM has moved to "coffeescript" (no hyphen)
/usr/local/bin/nrm -> /usr/local/lib/node_modules/nrm/cli.js
+ nrm@1.2.1
added 494 packages from 873 contributors in 100.184s

1.若成功查看nrm查看可選的源

帶*的是當(dāng)前使用的源

$ nrm ls

* npm -------- https://registry.npmjs.org/
  yarn ------- https://registry.yarnpkg.com/
  cnpm ------- http://r.cnpmjs.org/
  taobao ----- https://registry.npm.taobao.org/
  nj --------- https://registry.nodejitsu.com/
  npmMirror -- https://skimdb.npmjs.com/registry/
  edunpm ----- http://registry.enpmjs.org/

2.切換國內(nèi)源可加快下載速度

# 使用nrm工具切換淘寶源
$ npx nrm use taobao

# 如果之后需要切換回官方源可使用 
$ npx nrm use npm

切換taobao成功提示

Registry has been set to: https://registry.npm.taobao.org/

四.安裝Yarn

1.安裝工具Yarn

$ npm install -g yarn

/usr/local/bin/yarn -> /usr/local/lib/node_modules/yarn/bin/yarn.js
/usr/local/bin/yarnpkg -> /usr/local/lib/node_modules/yarn/bin/yarn.js
+ yarn@1.22.4
added 1 package in 16.735s

2.查看是否安裝成功

若成功則顯示版本號

$ yarn -v

1.22.4

五.下載開發(fā)工具Xcode（iOS平臺）

React Native 目前需要Xcode 10 或更高版本。你可以通過 App Store 或是到Apple 開發(fā)者官網(wǎng)上下載。這一步驟會同時安裝 Xcode IDE、Xcode 的命令行工具和 iOS 模擬器。

Xcode 的命令行工具

啟動 Xcode，并在Xcode | Preferences | Locations菜單中檢查一下是否裝有某個版本的Command Line Tools。Xcode 的命令行工具中包含一些必須的工具，比如git等。

六.創(chuàng)建新項目

必須要看的注意事項一：0.45 及以上版本需要依賴 boost 等幾個很難下載成功的第三方庫編譯。這里有中文網(wǎng)提供的國內(nèi)下載鏈接。

必須要看的注意事項二：0.60 及以上版本依賴CocoaPods安裝。CocoaPods的倉庫在國內(nèi)也很難訪問。如果在CocoaPods的安裝步驟卡很久，可以試一下這個國內(nèi)鏡像

1.先查看當(dāng)前react-native版本(我的是0.61.5)

2.創(chuàng)建新項目：參考React Native中文網(wǎng)—創(chuàng)建新項目

我的react-native版本是0.60以上，所以需要先安裝cocoapods

（1）桌面創(chuàng)建AwesomeProject的RN項目

$ cd Desktop
$ npx react-native init AwesomeProject

error Error: Failed to install CocoaPods dependencies for iOS project, which is required by this template.
Please try again manually: "cd ./AwesomeProject/ios && pod install".
CocoaPods documentation: https://cocoapods.org/

解決方法

1.查看pod源,我的是國內(nèi)鏡像源

$ pod repo

master
- Type: git (master)
- URL:  https://mirrors.tuna.tsinghua.edu.cn/git/CocoaPods/Specs.git

2.因此需要修改./AwesomeProject/iOS/Podfile，添加一行

source 'https://mirrors.tuna.tsinghua.edu.cn/git/CocoaPods/Specs.git'

3.保存修改Podfile，重新安裝

$ cd ./AwesomeProject/iOS

好吧，又失敗了，因為boost-for-react-native (1.63.0)這個太大了130M可能下載需要很長時間

RN依賴庫超時解決方法：

我的RN版本是0.60+,解決方法如下(其他版本參考：iOS RN 0.45以上版本所需的第三方編譯庫(boost等))：
- 1. 找到rn-third-party下pods_0.60+.zip
- 1. 解壓后的pods_0.60+文件夾與~/Library/Caches/CocoaPods/pods文件夾合并(merge)，如果沒有這個文件夾則創(chuàng)建一個
再次pod install 成功
