I am developing a Visual Studio Code extension (languageserver), and it worked perfectly fine. However, in order to use the latest languageserver features, I updated the vscode-languageclient to the latest version V7.0.0
npm install vscode-languageclient
After removing both node_modules and out folders, and recompiling with
npm install
npm build
npm run compile
I get a TON of compile errors. To show just a few:
node_modules/vscode-languageclient/lib/common/callHierarchy.d.ts:1:75 - error TS2305: Module '"vscode"' has no exported member 'CallHierarchyItem'.
1 import { Disposable, TextDocument, ProviderResult, Position as VPosition, CallHierarchyItem as VCallHierarchyItem [...]
node_modules/vscode-languageclient/lib/common/callHierarchy.d.ts:1:116 - error TS2305: Module '"vscode"' has no exported member 'CallHierarchyIncomingCall'.
1 import { Disposable, TextDocument, ProviderResult, Position as VPosition, CallHierarchyItem as VCallHierarchyItem, CallHierarchyIncomingCall as VCallHierarchyIncomingCall [...]
I am sure that I an missing something important here, but I have no idea what. Btw, the behavior is the same on linux and windows. Maybe somebody had a similar issue or knows what I am doing wrong. Thanks in advance!
As usual, after asking the question I figured it out almost right away.
I did not delete the package-lock.json file. This was the reason for the ton of error messages. It lead to some kind of version mismatch / inconsistency in the code base. So deleting it before executing npm install fixed this issue.
Then, however, the src/extension.ts file with the async function activate() inside showed some errors. The solution here - besides minor follow-ups - is to change
import { LanguageClient, LanguageClientOptions, ...} from 'vscode-languageclient';
to
import { LanguageClient, LanguageClientOptions, ...} from 'vscode-languageclient/node';
Just a follow up answer as this problem seemingly occurs very often: as of version 7.0.0 of the vscode-languageclient package, the codebase was split into "common", "node" and "browser".
split code into common, node and browser to allow using the LSP client and server npm modules in a Web browser via webpack. This is a breaking change and might lead to compile / runtime errors if not adopted. Every module has now three different exports which represent the split into common, node and browser. Lets look at vscode-jsonrpc for an example: (a) the import vscode-jsonrpc will only import the common code, (b) the import vscode-jsonrpc\node will import the common and the node code and (c) the import vscode-jsonrpc\browser will import the common and browser code.
Outdated docs are still floating around and it might not be obvious that "npm install vscode-languageclient" will get you the latest version that does not match the old documentation.
