Yarn 'TSC' is not an internal or external command, nor is it a runnable program or batch file. The problem that the command cannot be found after installing the global package

Use yarn Install a global package ：

yarn global add typescript

Enter at the command line tsc command Enter error ：

C:\Users\Administrator>tsc ‘tsc’ Not an internal or external command , It's not a runnable program Or batch files .

Solution ：

yarn global bin obtain yarn Global installation package path , Add to system environment variables .

C:\Users\Administrator>yarn global bin
C:\Users\Administrator\AppData\Local\Yarn\bin

And then in cmd Input in tsc command , Now it can be used normally .

C:\Users\Administrator>tsc Version 3.5.3 Syntax: tsc [options]
[file…] Examples: tsc hello.ts
tsc --outFile file.js file.ts
tsc @args.txt
tsc --build tsconfig.json

After adding environment variables , The terminal needs to be restarted , Re execution tsc command

C:\Users\adminCc>tsc -v Version 4.7.41
