La mia configurazione:
- Windows 10
- NVM 1.1.7 per Windows
- nodo 12.14.1 con npm 6.13.4
- Angolare 8.2.14 con @ angular / cli 8.3.22
Sto solo cercando di eseguire il modello angolare predefinito:
> npm install -g @angular/cli # this installed the angular version mentioned above
> ng new test # Chose default options for the project
> cd test
> npm ci # lots of error messages
L'ultimo comando provoca molti errori nell'output (ma non fallisce il comando):
> fsevents@1.2.11 install C:\test\node_modules\@angular\compiler-cli\node_modules\fsevents
> node-gyp rebuild
C:\test\node_modules\@angular\compiler-cli\node_modules\fsevents>if not defined npm_config_node_gyp (node "C:\Users\foo\AppData\Roaming\nvm\v12.14.1\node_modules\npm\node_modules\npm-lifecycle\node-gyp-bin\\..\..\node_modules\node-gyp\bin\node-gyp.js" rebuild ) else (node "C:\Users\foo\AppData\Roaming\nvm\v12.14.1\node_modules\npm\node_modules\node-gyp\bin\node-gyp.js" rebuild )

Tutti gli errori sono legati a fsevents
, node-gyp
e Python eseguibile non viene trovato. Esatto, non ho installato Python, ma non è un prerequisito per angolare.
Il comando in realtà termina con un codice 0 (che indica il successo - inoltre, ng build --prod
funziona dopo quello!) Ma sicuramente ci sono molti errori nell'output.
L'eliminazione node_modules
manuale della cartella e l'esecuzione npm install
anziché npm ci
produce un output che è molto più breve e senza errori. Inoltre, non modifica il package-lock.json
file, il che indica che sono installate le stesse versioni delle dipendenze.
Cosa sta succedendo? Perché tanti errori durante l'utilizzo npm ci
ma nessuno durante l'utilizzo npm install
?
