Goal: I try to update and add peer dependencies according to the error I got.

I expect the peer error messages to be gone but they are still there.

Error Messages:

npm WARN angular-cli-ghpages@0.6.2 requires a peer of @angular-devkit/architect@>=0.800.0 but none is installed. You must install peer dependencies yourself.

npm WARN angular-cli-ghpages@0.6.2 requires a peer of @angular-devkit/core@>=8.0.0 but none is installed. You must install peer dependencies yourself.

npm WARN angular-cli-ghpages@0.6.2 requires a peer of @angular-devkit/schematics@>=8.0.0 but none is installed. You must install peer dependencies yourself.

I tried the following commands:

npm install --save-dev "@angular-devkit/architect@>=0.800.0"

npm install --save-dev "@angular-devkit/schematics@>=8.0.0"

npm install --save-dev "@angular-devkit/core@>=8.0.0"

I also (After Shashank wrote me on the reply) deleted package-json.lock. Then typed the command "npm i" and got many messages such: npm WARN enoent SKIPPING OPTIONAL DEPENDENCY: ENOENT: no such file or directory, rename 'C:\web development\projects\frontend current backup 8 - Copy\urigrossltdWebsite\node_modules\webpack-dev-server\node_modules\fsevents\node_modules\yallist' -> 'C:\web development\projects\frontend current backup 8 - Copy\urigrossltdWebsite\node_modules\webpack-dev-server\node_modules\fsevents\node_modules.yallist.DELETE'

  • can you check and update question with the version which is there in package.json after running this command ? BTW, you can also check the exact version on `package-lock.json` file. Sometimes, its also safe to delete to delete `package-lock.json` and do `npm i` – Shashank Vivek Apr 04 '20 at 18:57
  • After deleting package-lock.json and did npm i : I noticed that it wrote me many lines such: npm WARN enoent SKIPPING OPTIONAL DEPENDENCY: ENOENT: no such file or directory, rename 'C:\web development\projects\frontend current backup 8 - Copy\urigrossltdWebsite\node_modules\watchpack\node_modules\fsevents\node_modules\wrappy' -> 'C:\web development\projects\frontend current backup 8 - Copy\urigrossltdWebsite\node_modules\watchpack\node_modules\fsevents\node_modules\.wrappy.DELETE' What should I do next? – Uri Gross Apr 04 '20 at 20:30
  • Take a look at https://stackoverflow.com/questions/48384811/npm-enoent-no-such-file-or-directory-error-when-installing-sails-js-dependenc . give a try to its answers and let me know if it solved this – Shashank Vivek Apr 05 '20 at 04:18
  • Ok, what about the peer dependencies error messages that refusing to go away? npm WARN angular-cli-ghpages@0.6.2 requires a peer of @angular-devkit/architect@>=0.800.0 but none is installed. You must install peer dependencies yourself. npm WARN angular-cli-ghpages@0.6.2 requires a peer of @angular-devkit/core@>=8.0.0 but none is installed. You must install peer dependencies yourself. npm WARN angular-cli-ghpages@0.6.2 requires a peer of @angular-devkit/schematics@>=8.0.0 but none is installed. You must install peer dependencies yourself. – Uri Gross Apr 05 '20 at 09:22
  • Ohhh.... is it still coming ? After deleting `lock` file and doing `npm i` with `"@angular-devkit/architect": "^0.901.0",` etc in package.json ? are u sure you are doing `ng s` in proper project ? This does not make sense. I hope its not a `npm package` for other project where you need to add it in `dependency` . https://stackoverflow.com/questions/18875674/whats-the-difference-between-dependencies-devdependencies-and-peerdependencies – Shashank Vivek Apr 05 '20 at 13:00
  • Can you confirm that you have directory created for all 3 under `node_modules` such as `C:\YOUR_PROJ\node_modules\@angular-devkit\architect` and so on ? – Shashank Vivek Apr 05 '20 at 13:01
  • for example it write the command : npm i @angular-devkit/schematics@>=8.0.0 I get the message: npm ERR! Cannot read property 'match' of undefined npm ERR! A complete log of this run can be found in: npm ERR! C:\Users\uri\AppData\Roaming\npm-cache\_logs\2020-04-26T18_07_36_438Z-debug.log Then package-lock.json created inside: @angular-devkit/schematics": { "version": "9.1.3", Seems like schematics version is updated but i still get the message : @angular-devkit/schematics@>=8.0.0 but none is installed. You must install peer dependencies yourself. – Uri Gross Apr 26 '20 at 18:12
  • On lock file I saw the latest version. But still I get the same message. I tried it on Schematics dependency On windows explorer i cannot see the folder @angular-devkit under node_modules at all. I can see it only on the vs-code explorer. Is it ok? see link with the screenshot. Thank you for helping :) https://ibb.co/pP3wfjK – Uri Gross Apr 26 '20 at 18:30
  • I do not see any link for screenshot in either comment or question. Can you see any relevant error in `2020-04-26T18_07_36_438Z-debug.log` ? It must be having some more details of this error – Shashank Vivek Apr 27 '20 at 03:57
  • Cannot read property 'match' of undefined Was in the log twice. I also attaching the log here https://shrib.com/#LavaGull6Gebj7k Maybe my package.json is messed up? – Uri Gross Apr 27 '20 at 16:03
  • Uri: As one last try. Can you delete `node_module` folder entirely and `package-lock.json` and do `npm i` . Last time I didnt ask you to delete the node_modules folder. Also, if that does not fix, can u try the same thing on some fresh workspace. I am sorry for guessing so many things. This is weird issue – Shashank Vivek Apr 27 '20 at 18:11
  • Thank you @ShashankVivek but this is still doesn't work after deleting node_module, package-lock and then npm i. By the way, when doing ng s it compiled all the modules as es5. It apparently unrelated to the current issue. I appreciate your efforts to help me - Stay safe :) – Uri Gross Apr 30 '20 at 19:25
