New React Native project with old version of react native
提问by Jordan Ell
I am trying to create a new react native project which should utilize an older version of react-native.
我正在尝试创建一个新的 React Native 项目，该项目应该使用旧版本的 react-native。
The result I would like would be to do something like: react-native init MyProjectbut have the version of react-native it uses be 0.13.2.
我想要的结果是做类似的事情：react-native init MyProject但是它使用的 react-native 版本是0.13.2.
However, there doesn't seem to be any options with react-native-clifor initializing with old versions of react-native.
但是，似乎没有任何选项可以react-native-cli使用旧版本的 react-native 进行初始化。
Performing react-native init MyProjectand then dowgrading react-native in package.jsonalso does not work because the initcommand installs a bunch of xcode templates which are used to build the app and there is no dowgradecommand which will dowgrade these templates. (There is an upgradecommand.)
执行react-native init MyProject然后降级 react-nativepackage.json也不起作用，因为该init命令安装了一堆用于构建应用程序的 xcode 模板，并且没有dowgrade可以降级这些模板的命令。（有一个upgrade命令。）
I tried downgrading my version of react-native-cli to 0.1.4which was current when react-native 0.13was current, but this did not work. From looking at the cli source, it seems it always initializes with just the newest version of react-native.
我尝试将我的 react-native-cli 版本降级到0.1.4当前 react-native0.13是最新版本，但这不起作用。从查看 cli 源代码来看，它似乎总是只使用最新版本的 react-native 进行初始化。
I realize this is pretty weird to want to start a new project at an old version, but I have a weird set of requirements that are forcing this.
我意识到想要在旧版本上开始一个新项目是很奇怪的，但是我有一组奇怪的要求迫使它这样做。

There is a new parameter in react-native initthat allows just this. Try:
有一个新参数react-native init允许这样做。尝试：
react-native init --version="[email protected]" MyNewApp
Here my source. I have successfully tested it with react-native-cli2.0.1.
这是我的来源。我已经成功地用react-native-cli2.0.1测试了它。

rninitis a replacement for react-native initthat allows you to specify a particular version of react-native to use.
rninit是替代react-native init它允许您指定要使用的特定版本的 react-native。

Try this:
尝试这个：
If you install the version of react-nativethat you want in your project, you can then navigate to (project)/node_modules/react-native/local-cli. Here you will see three generatorfolders which enclose the exact files RN would have used to initiate a project.
如果您react-native在项目中安装了所需版本，则可以导航到(project)/node_modules/react-native/local-cli. 在这里，您将看到三个generator文件夹，其中包含 RN 用于启动项目的确切文件。
It's a bit manual, but at least you'll have access to the original files.
这有点手动，但至少您可以访问原始文件。
