    ; userconfig C:\Users\amrish patidar\.npmrc
    registry = "http://registry.npmjs.org/"
    strict-ssl = true
    
    ; builtin config undefined
    prefix = "C:\\Users\\amrish patidar\\AppData\\Roaming\\npm"
    
    ; node bin location = C:\Program Files\nodejs\node.exe
    ; cwd = C:\Users\amrish patidar

Answer 1

也许你背后有一些代理，

试试这个

go 到设置>网络和 Internet>代理，然后关闭自动检测 Windows 上的自动代理设置下的设置。 然后它应该可以正常工作

Answer 2

go 通过@Amit K Khanchandani 的所有评论。 可能对您的情况有所帮助。

首先卸载nodejs和npm。 接下来安装两者的最新版本。 如果您收到 package.json 文件不存在的错误，则比运行 npx create-react-app projectname 。 非常重要的一点：“”如果它包含空格，请检查您的系统用户名，而不是问题的原因。 由于用户名中存在空格，您不能使用 cmd npx create-react-app 项目名称。

使用这个 cmd: npm install -g create-react-app(only once) 现在您可以使用 npx create-react-app projectname 创建项目
