node.js - As a centos7 root user, use npm to install yo. Is yo unusable?

Question

I installed node and npm as root user under centos.
Then install yo,

npm install -g yo

Running sanity checks on your system

✔ Global configuration file is valid
✔ Node.js version
✔ No .bowerrc file in home directory
✔ No .yo-rc.json file in home directory
✔ npm version
✔ NODE_PATH matches the npm root

Everything looks all right!
+ yo@2.0.0

However, when using yo, an error is reported.

[root@localhost address-book]# yo -v
/root/.node/lib/node_modules/yo/node_modules/insight/node_modules/configstore/index.js:53
                                throw err;
                                ^

Google didn't find the answer either. .
Isn’t it possible to install these with the root user?

Answer 1

You don't have access to this file.
It seems you don't have access to this file

Look at this file permissions.

ls -al /root/.config/configstore/insight-yo.json

Try to reinstall using the following command:

npm install --global yo --allow-root

Answer 2

I am running Ubuntu and have the same error as the original poster. Someone, please give me the answer. The method of changing access permissions does not work.

Answer 3

See GitHub Issue:

https://github.com/yeoman/yo/...

A feasible method is mentioned here: use NVM processing.

In addition, it is not recommended to use the root user to install the npm package. Various unpredictable problems often occur because you are the root user.
