After a review of Baidu has provided solutions are as follows:
need to delete npmrc file.
He stressed: nodejs not install the files in the directory npmrc npm module
but in C: \ Users {account} \ file under .npmrc
Then the question again, so where is this .npmrc file in it?
I was full-text search on this computer, a query for a long time, the result was nothing, and then query on .npmrc documents related
queries npmrc path can enter the following command
npm config ls -l
Then I went to the folder to find it and found no
just another run of the edit command If not, then the editor is empty,
npm config edit
Then pop-up text files, view text files in the directory address I found consistent with the above
and then turn to the next account in the user query under the c drive, this time there, and then delete the file and execute it clear cache command
npm cache clean --force
Then pack
npm install
====================== Method Two
Ide shut down the program, and then delete all the files in the node_modules, then npm install, if not enough, you can turn off the antivirus software
Method three ======================
we sometimes pull someone else's package-lock.json file on git, direct npm install may install an error, prompting package breakage and the like, and then install the entire package under / node_modules / file because of the lack of package failed to install.
1. Empty npm agent
npm config rm proxy
npm config rm https-proxy
2. Empty cache npm
npm cache clean -f
3. Delete package-lock.json directly
npm install
.Npmrc under 4. Delete the user directory
as long as you had configured in npm command line parameters, such as
npm config set registry https://registry.npm.taobao.org
The document will be generated in the user directory
Not so that. Eventually there will be damage to the bags of the installation does not go. In fact, I did not think the easiest way is to find damaged files, separate installation
npm install **@X.Y.Y
