Why do Node modules go into .staging folder?

问题

I have an Electron app that I'm trying to install node modules for. When I run npm install, it creates the node_modules folder but all the modules go into a subfolder called .staging. Each module also has -xxxxx appended to it, where the x's are some random alphanumerics.

Other Electron apps I've created have never done this. All the node modules sit in the root of node_modules and don't have -xxxxx appended.

Any idea why this is happening?

回答1:

This only happens temporarily until the modules are downloaded and installed. Node seems to do this so it can place together common submodules from all the modules you are installing so it can better structure the node modules folder(mainly for windows users).

If this is happening after an npm install finishes it is likely that there is something wrong with your node installation or something in the install failed.

I was also facing the same issue, I tried the steps below:

Delete package-lock.json
Delete Node Modules folder
Try installing it using below command (should be in open network)
```
npm install
```

Note: - ".staging" means, those dependencies are getting downloaded so for the temporary basis it keeps all those dependencies under ".staging" folder. Once all gets downloaded properly then it will showcase them under node_modules only.

I hope this will work.

I was having 2 versions of node installed on my system. nodejs v4.2 and node v8.6

I thought this could be conflicting, so I deleted nodejs v4.2 with following commands.

sudo apt-get remove nodejs

and linked the path with

sudo ln -s /usr/bin/node /usr/bin/nodejs

Again I ran npm install and it got fixed

I faced similar issue and tried the above answers but it did'nt worked for me; I followed below steps to resolve this issue-

1.npm audit

By running npm audit I got list of pending packages to install-

2.npm i packagename

After installing one or two package one by one from list, I used

3.npm install

At this time the installation went smooth without any lag or hangup. Hope this help who is facing similar issue :).

Delete package.lock.json
Delete node_modules
run npm update

回答6:

If you have a windows machine where you do not posses Admin rights to it.

Try deleting node_modules and install using 'npm install' from command line as

'ADMINISTRATOR'

It works!

Anyways, it comes down to an open network thing ;)

If you're automatically installing node_modules using CI/CD you should check out npm ci. Also check out this Stackoverflow question.

npm ci

The documentation points out the differences between npm install and npm ci.

The project must have an existing package-lock.json or npm-shrinkwrap.json
If dependencies in the package lock do not match those in package.json, npm ci will exit with an error, instead of updating the package lock.
npm ci can only install entire projects at a time: individual dependencies cannot be added with this command.
If a node_modules is already present, it will be automatically removed before npm ci begins its install. This is nice, because it prevents having to do something like rm -rf node_modules.
It will never write to package.json or any of the package-locks: installs are essentially frozen.
