Description

Summary

It appears that the text does not copy properly from this docusaurus warning message. The file which generates this message is packages/docusaurus/bin/beforeCli.mjs. This could be a non-docusaurus specific problem, but it does not appear to be a shell problem (I tried with zsh and bash).

I recently got this upgrade note, and wanted to upgrade my docusaurus version. I copy and pasted the command into my terminal, but the following happened:

(base) sanderschulhoff@Sanders-MacBook-Pro Learn_Prompting % npm i @docusaurus/core@latest @docusaurus/plugin-client-redirects@latest @docusaurus/plugin-google-analytics@latest     │
   │          @docusaurus/plugin-ideal-image@latest @docusaurus/preset-classic@latest @docusaurus/theme-mermaid@latest           │
   │                                          @docusaurus/module-type-aliases@latest
npm ERR! code EINVALIDTAGNAME

The | were quite weird as they didn't appear in the image I uploaded. I pasted the text elsewhere, and found that it pasted as:

npm i @docusaurus/core@latest @docusaurus/plugin-client-redirects@latest @docusaurus/plugin-google-analytics@latest     │
   │          @docusaurus/plugin-ideal-image@latest @docusaurus/preset-classic@latest @docusaurus/theme-mermaid@latest           │
   │                                          @docusaurus/module-type-aliases@latest

The terminal (a zsh shell) could not properly handle it. I asked GPT-4 to reformat it, and it gave me the following, which ran properly.

npm i @docusaurus/core@latest \
      @docusaurus/plugin-client-redirects@latest \
      @docusaurus/plugin-google-analytics@latest \
      @docusaurus/plugin-ideal-image@latest \
      @docusaurus/preset-classic@latest \
      @docusaurus/theme-mermaid@latest \
      @docusaurus/module-type-aliases@latest
