reactjs - 从 react 16.2.0 降级到 react 15.6.2 失败

Question

我最近从 react 15.6.2 升级到 react 16.2.0现在我的应用程序没有按预期工作，并且对 react 15.6.2 的依赖有很多警告所以对我来说，由于时间安排，现在不可能将所有其他依赖项升级到 16.2.0.。因此我想降级以响应 15.6.2

我运行以下命令再次安装 react 15.6.2:

npm install react@^15.6.2

我收到以下错误:

+-- UNMET PEER DEPENDENCY react@15.6.2 invalid
`-- UNMET PEER DEPENDENCY react-dom@16.2.0

当我将 package.json 更新为 "react": "^15.6.2" 时，出现以下错误:

npm ERR! Linux 3.13.0-36-generic
npm ERR! argv "/home/rakesh/.nvm/versions/node/v6.9.4/bin/node" "/home/rakesh/.nvm/versions/node/v6.9.4/bin/npm" "install"

有人知道为什么我无法降级吗？

Answer 1

我在 @HarshMakadia 和 @nkr 的帮助下解决了这个问题。感谢他们俩。这是任何其他面临相同问题的人的解决方案。

1.删除/重命名您当前的 node_modules 文件夹。
2.运行npm cache clean/sudo npm cache clean(Ubuntu 14.04)
3.手动更新您的 package.json 以将 react 和 react-dom 的版本从 16.0.2 更改为 15.6.2
4.运行npm install/sudo npm install(Ubuntu 14.04)

注意:将您的 node_modules 文件夹添加到任何 VCS(如 git)以防止此类问题
