I encountered a permission denied error while attempting to execute the command npm install -g tsc

My main objective is to convert TypeScript code to JavaScript. However, when I attempted to install the TypeScript compiler globally using 'npm install -g tsc', I encountered the following error:

npm ERR! Error: EACCES: permission denied, rename '/usr/local/lib/node_modules/tsc' -> '/usr/local/lib/node_modules/.tsc-8BsQC1RP'

To resolve this issue, I tried running the command with admin privileges by using 'sudo npm install -g tsc'. The installation was successful without any errors. But even after that, when I ran the 'tsc' command again, I faced an error.

The error message displayed: "This is not the tsc command you are looking for. To gain access to the TypeScript compiler, tsc, through the command line, you can either:

  • Install TypeScript in your project first using 'npm install typescript' and then use 'npx'
  • Use 'yarn' to prevent accidental execution of code from uninstalled packages

My ultimate goal remains to convert TypeScript files to JavaScript successfully.

Answer №1

The tsc package on NPM is considered outdated.

According to the information provided in the linked NPM listing, it is recommended to install typescript instead "if you need access to the tsc CLI command".

npm install -g typescript
