After updating nvim-lspconfig, some lsp-plugins do not work anymore (`command is not executable`)

• What language server(If the problem is related to a specific language server): tsserver
• Can you reproduce this behavior on other language server clients (vscode, languageclient-neovim, coc.nvim, etc.): yes, for example json
• Operating system/version: macOS Big Sur
• Terminal name/version: iTerm2
• $TERM: xterm-256color

How to reproduce the problem from neovim startup

Open a file configured for the javascript/typescript language server or a json file.

Actual behaviour

Error executing "FileType Autokommandos für "javascript"":
E5108: Error executing lua .../share/nvim-osx64/share/nvim/runtime/lua/vim/lsp/rpc.lua:319: The given command "typescript-language-server" is not executable.

Expected behaviour

No error, LSP is loaded/started.

We deprecated the older installer, so if you used :LspInstall before, you'll need to reinstall

npm install -g typescript typescript-language-server

Thanks! This was not obvious for me, works now.
