Question

我刚开始使用react-native项目，并且正在尝试设置一个演示项目以学习本地反应。但是，我无法通过命令行创建项目。

在安装必备库之后，我使用以下命令创建react-native项目：

react-native init AwesomeProj

我收到以下错误：

我试图找到这个问题的解决方案，但找不到任何有效的方法。任何人都知道如何解决这个问题？

P.S。我在Mac上做这个（如果这有什么不同）

Answer 1

我检查了互联网问题，还ping了registry.npmjs.org，一切正常。为了解决这个问题，我使用以下命令安装了纱线：

brew install yarn

似乎解决了这个问题。如果任何人在使用react-native开始时遇到同样的问题，我会把它放在这里。

Answer 2

npm cache clean --force

运行此命令首先为我解决了该问题。

Answer 3

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

或手动安装纱线。

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

Answer 4

我解决了这个问题，手动下载并安装了纱线

使用命令：

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

创建react-native项目时出现命令行错误
