无法安装 create-react-app

Question

I am following https://hackernoon.com/simple-react-development-in-2017-113bd563691f
I am new to React ecosystem and I just now installed Yarn

➜  WebstormProjects yarn --version
0.23.2

Then I installed created-react-app as mentioned in the docs as

➜  WebstormProjects yarn global add create-react-app
yarn global v0.23.2
warning No license field
[1/4] 🔍  Resolving packages...
[2/4] 🚚  Fetching packages...
[3/4] 🔗  Linking dependencies...
[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.

Then, I tried creating app

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

Then, I headed over https://github.com/facebookincubator/create-react-app and tried installing using npm as

➜  WebstormProjects npm install -g create-react-app

npm ERR! addLocal Could not install /Users/Harit.Himanshu/WebstormProjects/create-react-app

npm ERR! Please include the following file with any support request:
npm ERR!     /Users/Harit.Himanshu/.npm/_logs/2017-04-15T03_06_22_478Z-debug.log

The node and npm versions I have are

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

What mistake I am making?

Answer 1

Based on npm 's output, it's interpreting your command as an attempt to install a package contained in a local directory globally. You might want to try rm -rf create-react-app && sudo npm i -g create-react-app within that same directory.

Answer 2

1. Try to run the terminal with Run as Administrator
2. Cd to ~ cd ~
3. Run the command npm cache clean --force
4. Then run the command npm install -g npm@latest --force
5. Now again run the command npm cache clean --force
6. Finally, run the command npx create-react-app my-app
7. If it works let me know, Used HYPER TERMINAL to install
