问题描述

我正在通过遵循此处的官方文档来开始起步，以响应本机教程

I am Beginning the getting started react native tutorial by following the official docs from here https://facebook.github.io/react-native/docs/getting-started.html

1. 顺利安装choco，nodejs和python
2. 在执行npm install -g react-native-cli时，我得到无法读取null的属性'path'"(下面是完整错误)

npm install -g react-native-cli

这是我尝试过的，

1. 检查了文件夹"C:\ Program Files \ nodejs \ node_modules"的权限，发现其为只读
2. 已将所有权转让给我和管理员用户，并对其拥有完全控制权，然后通过attrib -r -s C:\ Program Files \ nodejs \ node_modules/S/D删除了只读权限
3. 当我检查文件夹的权限时，它仍然是只读的，但其中的所有文件都不处于只读的控制下
4. 再次执行"npm install react-native-cli"命令，导致相同的错误

解决方案

1. 如果您以前使用过Sinopia并创建了.npmrc文件，请重命名或删除配置文件
2. 使用npm install -g react-native-cli成功安装lib

理由

1. Sinopia配置文件将使npm首先在本地计算机上查找软件包，如果找不到，则在npmjs.com上获取软件包
2. 我之前安装并使用了Sinopia，后来又卸载了它，但看起来配置文件并未被删除3.因此，配置文件使npm在本地计算机上查找软件包，而本地服务器根本没有运行，表明软件包不可用！

推荐答案

我认为您正在使用代理，是" http://localhost:4873/您代理(或设置自定义注册表)?如果是这样，则最好检查一下网络，并确保可以使用npm正常安装其他模块.

I think you're using a proxy, is "http://localhost:4873/" you proxy(or you set a custom registry)? If it is, you had better check your network, and make sure your can use npm to install others module normally.

错误:连接ECONNREFUSED 127.0.0.1:4873"表明它无法连接到127.0.0.1:4873

"Error: connect ECONNREFUSED 127.0.0.1:4873" shows that it can not connect to 127.0.0.1:4873
