创建React Native项目时出现命令行错误

创建React Native项目时出现命令行错误

5

我刚开始接触 react-native 项目，试图设置一个示例项目来学习 react-native。然而，我无法通过命令行创建项目。

在安装了必要的库之后，我使用以下命令创建 react-native 项目：

react-native init AwesomeProj

I get the following error:

我尝试寻找解决此问题的方法，但是没有找到有效的方法。有人知道如何解决吗？

看起来你的网络连接有问题。你能 ping registry.npmjs.org 吗？你尝试过使用其他互联网连接吗？ - Wanda Ichsanul Isra

npm cache clean --force 
brew install yarn
npm install --save --save-exact react-native

或手动安装yarn。

cd /opt
wget https://yarnpkg.com/latest.tar.gz
tar zvxf latest.tar.gz

然后运行

npm install --save --save-exact react-native

npm cache clean --force

运行这个命令首先为我解决了问题。

我通过手动下载和安装yarn来解决了这个问题

使用以下命令：

yarn config set "strict-ssl" false -g  
yarn add react-native --exact

我检查了网络问题并且ping了registry.npmjs.org，一切都工作正常。为了解决这个问题，我使用以下命令安装了yarn：

brew install yarn

看起来问题已经解决了。如果有人在使用React Native时遇到同样的问题，我会把这个放在这里。
