由于依赖关系无法升级 React-Native 项目

Question

我正在尝试将我的 RN 项目从 0.62.2 更新到最新版本（当前为 0.63.3）。 我只是运行npm update并得到错误：

npm ERR! Found: react@17.0.1
npm ERR! node_modules/react
npm ERR!   react@"^17.0.1" from the root project
npm ERR! 
npm ERR! Could not resolve dependency:
npm ERR! peer react@"16.13.1" from react-native@0.63.3
npm ERR! node_modules/react-native
npm ERR!   react-native@"^0.63.3" from the root project
npm ERR! 
npm ERR! Fix the upstream dependency conflict, or retry
npm ERR! this command with --force, or --legacy-peer-deps
npm ERR! to accept an incorrect (and potentially broken) dependency resolution.

在运行npm update之前，我运行了 npx npx npm-check-updates -u并得到以下信息：

 @react-native-community/netinfo          ^5.9.5  →   ^5.9.9

 axios                                   ^0.19.2  →  ^0.21.0

 react-native-base64                       0.0.2  →    0.1.0     
 react-native-gesture-handler             ~1.5.0  →   ~1.9.0     
 react-native-reanimated                  ~1.4.0  →  ~1.13.2     
 react-native-safe-area-context           ^0.7.3  →   ^3.1.9     
 react-native-screens             2.0.0-alpha.12  →   2.15.0     
 react-native-simple-crypto              ^0.2.13  →  ^0.2.15     
 react-native-vector-icons                ^6.7.0  →   ^7.1.0     
 react-navigation                         ^4.4.0  →   ^4.4.3     
 @babel/core                               7.8.7  →   7.12.9     
 @babel/runtime                            7.8.7  →   7.12.5     
 babel-jest                               24.9.0  →   26.6.3     
 metro-react-native-babel-preset          0.56.4  →   0.64.0     
 react-test-renderer                      16.9.0  →   17.0.1   

好的，我从错误中总结出react-native@0.63.3对于需要react@16.13.1的react@^17.0.1是错误的，但这是由 npx npx npm-check-updates -u产生的 - 为什么它会导致不兼容的 deps树？..

如果我将手动反应版本更改为“^16.0.0”， npm install失败：

npm ERR! Found: react@16.14.0
npm ERR! node_modules/react
npm ERR!   react@"^16.0.0" from the root project
npm ERR! 
npm ERR! Could not resolve dependency:
npm ERR! peer react@"16.13.1" from react-native@0.63.3
npm ERR! node_modules/react-native
npm ERR!   react-native@"^0.63.3" from the root project

为什么是“react@16.14.0”？？ 从哪里？

我只是不明白这一切是如何运作的。请建议。

我目前的package.json ：

  "name": "Proj",
  "version": "0.0.1",
  "private": true,
  "scripts": {

  },
  "rnpm": {
    "assets": [
      "./assets/fonts/"
    ]
  }
}

更新

根据@anthony-marino 的建议，我通过update helper进行了手动依赖项更新，然后我回到了让我升级的问题！

npm ERR! Found: react@16.13.1
npm ERR! node_modules/react
npm ERR!   react@"16.13.1" from the root project
npm ERR!   peer react@"^16.0" from @react-native-community/viewpager@4.2.1

npm ERR! node_modules/react-native-zeroconf
npm ERR!   react-native-zeroconf@"github:atlascoder/react-native-zeroconf" from the root project
npm ERR! 

而让我失望的东西..

我有一个from @react-native-community/viewpager的组件，为什么它需要 peerDep react@"^16.0" - 为什么它不接受react@16.13.1 。 ^16.0意味着比16.*更新鲜，不是吗？！ 当我在npm semver 计算器上检查^16.0时 - 它显示16.13.1适合..

解决方法

在更新时遇到这个麻烦：

1. 删除node_modules和package-lock.json
2. npm i
3. 当npm i失败时 - 删除失败的依赖项
4. npm i完成后 - 手动安装删除的依赖项

Answer 1

我最近经历了这个......使用升级助手。 手动进行每次更改都很痛苦，但它确实有效！

Answer 2

从您的日志中：react-native 0.63.3 需要 react@"16.13.1"，但发现 react@"^17.0.1"。 只需通过npm install react@16.13.1降级您的反应，然后再次尝试npm install 。 它应该可以正常工作。 如果你运行 npm outdated 你会看到“react”已经过时了。 但是您不太可能将所有软件包都安装在最新版本中。

Answer 3

所以当我从 RN 0.63.1迁移到0.64.1时，我也遇到了这个问题，所以我以这种方式解决了它：

1. 步骤运行npx react-native upgrade对我来说它更新了react和react-native
2. 然后我手动更新了这些依赖项：

"@babel/core": "^7.12.9",
"@babel/runtime": "^7.12.5",
"@react-native-community/eslint-config": "^2.0.0",
"babel-jest": "^26.6.3",
"eslint": "7.14.0",
"jest": "^26.6.3",
"metro-react-native-babel-preset": "^0.64.0",
"react-test-renderer": "17.0.1"

you could use this tool to see what changes did these command npx react-native upgrade and what changes you have to do it manualy https://react-native-community.github.io/upgrade-helper/?from=0.63.1&to=0.64 .1

3. 然后运行npm install --force以使用您手动添加的新依赖项更新package-lock.json 。 如果您可能对 Jest 进行了测试，那么您还必须将 go 调整为jest.configs.js并确保您在这里有react-native和@react-native

transformIgnorePatterns: [
    'node_modules/(?!(jest-)?react-native|@react-native|@react-native-community)',
  ],

可能你也会对这些模拟有一些问题

// The old way
jest.mock('react-native/Libraries/Animated/src/NativeAnimatedHelper');
// Here path was updated
jest.mock('react-native/Libraries/Animated/NativeAnimatedHelper');

现在你应该对 go 很好，这个例子是为了将 RN 从 0.63.1 升级到 0.64.1，但它也可以为你工作。

ps 我正在使用node -v 14.15.4和npm -v 7.7.6如果你使用 npm v6，你可能会遇到更少的问题

Answer 4

这解决了我的问题。

npm install @react-native-community/masked-view --force

Answer 5

我不得不使用：

npm i --legacy-peer-deps
