無法安裝 create-react-app

Question

我正在關注https://hackernoon.com/simple-react-development-in-2017-113bd563691f
我是React生態系統的新手，我剛剛安裝了Yarn

➜  WebstormProjects yarn --version
0.23.2

然后我按照文檔中的說明安裝了created-react-app

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

success Installed "create-react-app@1.3.0" with binaries:
      - create-react-app
warning No license field
✨  Done in 0.82s.

然后，我嘗試創建應用程序

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

然后，我前往https://github.com/facebookincubator/create-react-app並嘗試使用npm安裝

➜  WebstormProjects npm install -g create-react-app

我擁有的node和npm版本是

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

我犯了什么錯誤？

Answer 1

根據npm的輸出，它將您的命令解釋為嘗試全局安裝包含在本地目錄中的包。 您可能想在同一目錄中嘗試rm -rf create-react-app && sudo npm i -g create-react-app 。

Answer 2

1. 嘗試以管理員身份運行終端
2. cd to ~ cd ~
3. 運行命令npm cache clean --force
4. 然后運行命令npm install -g npm@latest --force
5. 現在再次運行命令npm cache clean --force
6. 最后，運行命令npx create-react-app my-app
7. 如果可行，請告訴我，使用 HYPER TERMINAL 進行安裝
