error MSB8007 while downloading dependencies with npm and node - node.js

Question

I am trying to install some packages in my node app with npm, and I keep getting the error below. I get the same error with socket.io and mongo. I have gone through a number of different errors similar to this, and have install so many different things as per suggestion in other threads that I really have no idea what the problem is. If anyone has any suggestion as to what I need to download/set I would greatly appreciate it.

Answer 1

VS C++ Express 2010 32bit is free. if you installed 64bit edition of nodejs just remove it and install 32 bit version of the node.js

I had a simallar problem, and this is my solution. I am running windows 7 x64. I installed the x64 version of nodejs. I tried to run install and this is what I got:
At first it wanted me to put git into my path, which I did. then it wanted me to install python (not version 3.x.x but 2.x.x) and put that in my path, which I did. Then I installed visual studio 2010 (c++). after I did all of this I got this error:
D:\Source\xxxx\grunt-raptr\node_modules\node_modules\libxmljs\build\vendor\libxml\libxml.vcxproj(18,3): error MSB4019: The imported project "D:\Microsoft.Cpp.Default.props" was not found. Confirm that the path in the declaration is correct, and that the file exists on disk.
I read somewhere that if you run it in the visual studio cmd you can make it work, I tried that and I got this error:
C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Microsoft.Cpp.InvalidPlatform.Targets(23,7): error MSB8007: The Platform for project 'libxml.vcxproj' is invalid. Platform='x64'. You may be seeing this message because you are trying to build a project without a solution file, and have specified a non-default Platform that doesn't exist for this project. [D:\Source\xxxx\node_modules\grunt-raptr\node_modules\libxmljs\build\vendor\libxml\libxml.
vcxproj]
Once I saw this I re-installed nodejs with the x32 version and everything worked.
I hope this helps someone.

While trying to install node-inspector: C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Microsoft.Cpp.InvalidPlatform.Targets(23,7): error MSB8007: The Platform for project 'bufferutil.vcxproj' is invalid. Platform='x64'
My machine:
Win 7 64bit
node 0.12.7 64bit
Python 2.7 64bit
How I fixed it with all the advice found on the nets:
Uninstall all VC++ 20xx Redistributables
(use this MS FixIt if the uninstall fails)
Install Microsoft Windows SDK for Windows 7
Select only Visual C++ Compilers
Run npm install -g node-inspector --python="C:\Python27\python.exe"
If that still doesn't work try this:
install the MS SDK x64 Libraries
add this line 'AdditionalLibraryDirectories': 'C:\\Program Files\\Microsoft SDKs\\Windows\\v7.1\\Lib\\x64', in every addon.gypi you find
C:\nodejs\node_modules\node-gyp\addon.gypi
C:\Users\YOU\.node-gyp\0.12.7\deps\npm\node_modules\node-gyp\addon.gypi
?
addon.gypi:
...
'msvs_settings': {
'VCLinkerTool': {
'DelayLoadDLLs': [ 'iojs.exe', 'node.exe' ],
# Don't print a linker warning when no imports from either .exe
# are used.
'AdditionalOptions': [ '/ignore:4199' ],
# THIS LINE HERE
'AdditionalLibraryDirectories': 'C:\\Program Files\\Microsoft SDKs\\Windows\\v7.1\\Lib\\x64',
},
...
Good luck!
