Vue-cli 3: “command failed: npm install --loglevel error”

问题

Every time I try to create a new project (vue create my-project), I get this error:

ERROR : command failed: npm install --loglevel error

I'm on PC / Windows 10, Vue-cli 3.2.1, Node 8.11.3, Npm 5.6.0. Presets: Babel, ESLint & Prettier, SASS, Vue router, Vuex

From the log:

2736 silly saveTree `-- vuex@3.0.1

2737 warn ajv-keywords@2.1.1 requires a peer of ajv@^5.0.0 but none is installed. You must install peer dependencies yourself.

2738 verbose stack Error: EINVAL: invalid argument, read

Any idea what that means and how to solve it?

EDIT: I figured out that excluding any lint feature makes the problem disappear. So the question becomes: how can I still use linting and make it work?

回答1:

Try

npm cache clean --force

If it doesn't work then manually delete %appdata%\npm-cache folder. Then try to create the project again.

回答2:

I've tried everything above but still the error kept occuring. Finally I upgraded my npm version and node version, both to the latest ones and it worked.

回答3:

I am using "vue-cli 3.0.0-rc.1", I solve the problems by setting the ~/.vuerc from "useTaobaoRegistry": true, to false. Hope it help to you!!

回答4:

I am using vue-cli 3.7.0-rc.1, I solve the problems by editing the ~/.vuerc from "useTaobaoRegistry": false to true.

Hope it works for you!

回答5:

回答6:

%appdata%\npm-cache Just run on the "Run" Then Delete all the files
npm install -g @vue/cli
Just use npm 6 or greater
vue create projectName

Likely issue is your proxy settings:

I was having this issue recur intermittently and in the end I found out it was being caused by network proxy issues. See this article on how run npm behind a proxy server
