无法安装 create-react-app

Question

我关注https://hackernoon.com/simple-react-development-in-2017-113bd563691f
我是 React 生态系统的新手，我刚刚安装了 Yarn

➜  WebstormProjects yarn --version
0.23.2

然后我按照文档中提到的

安装了 created-react-app

➜  WebstormProjects yarn global add create-react-app
yarn global v0.23.2
warning No license field

[4/4]   Building fresh packages...
success Installed "create-react-app@1.3.0" with binaries:
      - create-react-app
warning No license field
✨  Done in 0.82s.

然后，我尝试创建应用

➜  WebstormProjects create-react-app myproject
zsh: command not found: create-react-app

然后，我转向 https://github.com/facebookincubator/create-react-app 并尝试使用 npm 作为

安装

➜  WebstormProjects npm install -g create-react-app

我的node和npm版本是

➜  WebstormProjects node --version
v7.9.0
➜  WebstormProjects npm --version
4.2.0
➜  WebstormProjects

我犯了什么错误？

Answer 1

根据 npm 的输出，它将您的命令解释为尝试全局安装包含在本地目录中的包。您可能想在同一目录中尝试 rm -rf create-react-app && sudo npm i -g create-react-app。

Answer 2

尝试运行以运行为管理员的终端
CD ~ cd ~
运行命令npm cache clean --force
然后运行命令npm install -g npm@latest --force
现在再次运行命令npm cache clean --force
最后，运行命令npx create-react-app my-app
如果有效请告诉我，使用超级终端安装
