Windows中的NPM未安装模块或未添加到package.json

Question

I have no idea why I get an error for mongoskin . I used this module before but I got rid of it. I removed the node_modules directory then did a fresh npm install, fine everything installs. Then I tried to add a new module minimist as seen below:

C:\www\instantynode\src>npm install minimist --save

npm install minimist --save does not work as you can see, does not install or add itself to the package.json file. And it is still mentioning mongoskin ?

I have a feeling that the NPM in Windows is buggy?

Answer 1

You are trying to install minimist, which has its own package.json with its own dependencies. In these it says that it wants mongoskin to be installed, which has a dependency on mongodb itself, but in another version than you have it (you have 2.1.4 but as the error says, it needs ~1.4).

So, because you provided the --save parameter, you want npm to respect these dependencies and do not install mongodb in the desired version on top of it.

Answer 2

i think that mongoskin only work with mongodb driver older than 1.4. You might have installed mongoskin in global mode, try to remove it.

Answer 3

Ok I've found the issue. The NPM in Windows is way more sensitive than the one in Linux. In Linux I can manually remove the line from the package.json file and just remove the node_modules directory. However in Windows it appears to be cached by NPM, so I had to manually use the npm remove mongoskin --save command.

When I did this so that the package.json looked like it should I was able to install minimist via npm install minimist --save without issues!

I'm not surprised Windows... Not surprised...

Answer 4

In your package.json, try to change this:

"mongodb": "2.1.4",

to this:

"mongodb": "1.4.*",
