react-native:无法识别命令"run-android".可能是npm install引起的 [英] react-native: Command `run-android` unrecognized. Maybe caused by npm install

问题描述

最近，当我安装本机包时，我开始遇到此问题(例如: react-navigation )进入我的项目，一堆软件包被删除(包括我认为的react，react-native).

Recently I started getting this issue, when I install a react-native package (eg: react-navigation) into my project, a whole bunch of packages are been removed (including react, react-native i think).

然后当我尝试运行命令" run-android "时，它说它无法识别.

And then when i try to run command "run-android", it says it doesn't recognize.

我最近更新到了最新的 npm 和 react-native-cli ." npm install "有什么问题吗?还是 react-native ?

I recently updated to the latest npm and react-native-cli. Is it something wrong with "npm install"? or react-native?

node version: 8.1.2 <br/>
react-native-cli: 2.0.1 <br/>
react-native: 0.45.1 <br/>
react-navigation: 1.0.0-beta.11

以下是重新创建的步骤:

Below are the steps to re-create:

• 步骤1-创建项目.

• Step 1 - Create project.

步骤2-运行"run-android"命令(有效).

Step 2 - Run the "run-android" command (This works).

步骤3-将"react-native-navigation"安装到项目中.

Step 3 - Install "react-native-navigation" into project.

Notice in the image above. Seems like all the other packages are removed from the project.<br/><br/>

• 第4步-尝试再次运行"run-android"命令.(将失败，但之前曾工作过)

对这个问题是什么以及有什么解决办法的任何想法吗?

Any idea on what the issue is and any way to solve it?

推荐答案

找到了解决方案

Found the solution here.

起初运行 npm install 无效，但是随后删除 package-lock.json 文件并运行 npm install 即可工作.

At first running npm install didn't work, but then, deleting the package-lock.json file and running npm install did the job.

此后，我分别安装了 react-navigation 软件包，并且运行良好.

After that I installed react-navigation package seperately and it worked fine.
