Error running npm install

[im1dermike]

Today, I started getting errors when running npm install on my solution. The error referenced "microtime" which I assume is a dependency of one of my packages. This was the original error:

C:\Development\node_modules\microtime>if not defined npm_config_node_gyp (node "C:\Users\me\AppData\Roaming\npm\node_modules\npm\bin\node-gyp-bin\....\node_modules\node-gyp\bin\node-gyp.js" rebuild ) else (node "" rebuild )

I did some researching and trying of suggested solutions. I believe at some point I ran npm install -g node-gyp. Now when I try to run npm install microtime@latest, I get the following error:

Your first error says:

gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable.

So check that you have python installed and set up correctly.

The second error says:

File "C:\Users\me\AppData\Roaming\npm\node_modules\npm\node_modules\node-gyp\gyp\pylib\gyp\MSVSVersion.py", line 434, in SelectVisualStudioVersion
versions = _DetectVisualStudioVersions(version_map[version], 'e' in version)
KeyError: '2017'

I'm guessing you are using VS2017? It looks like support for that version was added in node-gyp 3.6.0, so try upgrading your node-gyp.

[im1dermike]

Here is my challenge... this is for a web application. Why python would be needed for whatever javascript library is using is it concerning.

Ignoring that, I just tried to install that specific version of node-gyp (which is a dependency for who knows what library I'm importing) and get this:

I think you probably need to open a ticket on https://github.com/nodejs/node-gyp because it appears your error is happening in there, before the build steps really get to this library.

[im1dermike]

For posterity: nodejs/node-gyp#1195

[ukphillips]

I still think this might be an issue with microtime, here is the error I have:

C:\Users\k_phillips\test ([email protected])
npm install [email protected]

[wadey]

@ukphillips The key error in there is:

TRACKER : error TRK0005: Failed to locate: "CL.exe". The system cannot find the file specified. 

Without CL.exe, no native modules can be built. Please install the required tools listed here: https://github.com/nodejs/node-gyp#installation (see the Windows section).

I think the issue that affected everyone here is browserify/pbkdf2@ad53c33. That bump essentially screwed over everyone using browserify.

I can verify that running the following in an elevated CMD works on Windows (after installing Python 2.7 and setting %PYTHON%):

npm install --global --production windows-build-tools
npm install -g npm

[gibfahn]

Here is my challenge... this is for a web application. Why python would be needed for whatever javascript library is using is it concerning.

@im1dermike Native node modules use the GYP build system, which is written in Python. If you're using node-gyp (through npm install or directly) you're compiling a native npm package, which means you need the compiler dependencies (i.e. a C++ compiler and Python).

[wadey]

@cadsit the latest version of pbkdf2 has microtime listed as an optional dependency, so even if you see an error during install it shouldn't fail:

https://github.com/crypto-browserify/pbkdf2/blob/v3.0.11/package.json#L57-L59

[abock]

I second @cadsit's findings. We also initially worked around this breakage by pinning pbkdf2 to an older version:

"devDependencies": {
  "pbkdf2": "=3.0.9"
}

Basically, https://github.com/crypto-browserify/pbkdf2, should have done a larger version bump due to the build implications (@calvinmetcalf).

@wadey it's specified as optional on GitHub but it's definitely not optional in npm. From node_modules/pbkdf2/package.json on disk, freshly installed:

  "dependencies": {
    "create-hash": "^1.1.2",
    "create-hmac": "^1.1.4",
    "microtime": "^2.1.3",
    "ripemd160": "^2.0.1",
    "safe-buffer": "^5.0.1",
    "sha.js": "^2.4.8"
  },

[abock]

There are also a number of issues already opened about this against pbkdf2. This issue should probably be closed since it's not specifically @wadey's issue.

• Make microtime a devDependency again browserify/pbkdf2#63
• Issues after 3.0.11 update browserify/pbkdf2#64
• Issue with microtime on windows after 3.0.11 browserify/pbkdf2#65

[calvinmetcalf]

and we're fixed

[ukphillips]

I'm still relatively new to npm - while this did fix my issue, I'm having a hard time grasping how the change resolved (and created) the problem. pbkdf2 from looking at the dependencies depends on microtime - how did making a change to pbkdf2 affect the ability to install microtime?

[wadey]

@ukphillips your computer is not set up to compile and build any native C++ modules (like microtime). You didn't notice before because nothing in your project used native modules, but when pbkdf2 added microtime as a dependency you encountered your first native module. So the answer is, your computer could never install microtime, you just didn't notice before. If you want to install native modules, you need to follow these steps: https://github.com/nodejs/node-gyp#installation

I just re-ran the automated builds and microtime builds on windows for all current versions of Node.js: https://ci.appveyor.com/project/WadeSimmons/node-microtime/build/88

[calvinmetcalf]

how did making a change to pbkdf2 affect the ability to install microtime?

I removed microtime from the pbkdf2 dependencies so that now you were no longer trying to install it

[wadey]

FYI to everyone that had issues here. The latest release (2.1.4) of microtime now uses node-pre-gyp to provide pre-built binaries for Windows users.

I can`t understand it....

I've also got the similar error when I tried installing vue-funnel-graph-js package in nuxt. I've searched a lot but didn't find a proper solution. I've also tried both with python3 and python2 but still won't work.
Any idea about how to fix it? Thankyou.
