Can't install web3 version 1.2 on Windows 10

[taducquang]

Hi, i don't know why but seem like i can't install web3's latest version even on new project on Windows 10.
Command:
npm install web3 or yarn add web3

Details of Error:

rm -rf node_modules/websocket/.git

'rm' is not recognized as an internal or external command,
operable program or batch file.

I have encountered the same problem

This is because package web3-providers-ws uses pre-install script which contains rm command to delete websocket's .git directory. But rm command is not availible on Windows.

To clarify what @filips123 said: This is a bug in web3 and currently makes 1.2.x incompatible with Windows. Needs to be fixed.

[filips123]

@levino Why does package need to delete .git directory? If it is really needed, it needs to be fixed to use rm -r or rmdir depending on what's available.

[levino]

I was not talking about a fix. I was talking about the status quo: You cannot install this package on Windows atm. I do not know why there is a preinstall script and I have not looked into how this can be fixed. Your analysis above sounds right. I just wanted to clarify that this is a bug that needs to be fixed here. One could read your comment like instructions for a workaround, which they are not.

The preinstall script is a red herring, and isn't needed; it should be removed from web3-providers-ws because it's pointless. rm works fine on Windows, not sure exactly what's gone wrong in this case, but I think it's a permissions problem.

There's a nasty bug in npm that's fixed in 6.10.1: https://npm.community/t/installing-with-git-url-results-in-spurious-git-directory-within-node-modules/8815.

(this after-effects of this bug can manifest weird behavior on Windows like not being able to delete sudirs in node_modules, no idea why though)

To overcome this problem, you may need to do a combination of the following, or all of them:

• upgrade to npm 6.10.1 or newer
• clear your npm cache: npm cache clear --force
• delete your project's node_modules directory
• manually edit your project's package-lock.json or as a last resort delete it and regenerate it.

On Windows I found I had to upgrade to the latest npm (6.10.2) and/or I had to run npm cache clear --force in an admin shell... I'm not sure which of those things did the trick, maybe both together. But it's definitely an npm thing, not a problem with web3 per se.

[taducquang]

Not really an idea solution if i have to upgrade npm since it comes with nodejs LTS version.
How about Yarn @michaelsbradleyjr?

• I installed the latest version of Node-Gyph because apparently the current version is not compatible with Node 12.x: Fails to install with node 12 microsoft/node-pty#319
• I did an upgrade of npm by doing this: npm install -g npm
• After that I cleaned the npm cache: npm cache clear --force
• I removed the node_modules and package-lock.json
• Restarted my terminal and executed npm install.

I still run into the same error though:

@devedse the screenshot helped me understand, thank you! @taducquang I apologize for a bit of misdirection in my previous replies. Indeed, rm isn't available in cmd.exe by default.

I've kept a Windows laptop (or at least a VM) around for cross-platform testing the past couple of years, but one of the first things I do when setting up a Windows environment is install tools like cmder and Git for Windows (note: there is a cmder download that bundles the two things). That makes *nix commands like rm available in the shell (note it's not a bash shell, it's an augmented cmd.exe environment that cmder provides).

So the "fix" in this case will be to remove the preinstall script from web3-providers-ws. I'll make a PR shortly. An alternative fix, if the preinstall script was actually needed, would be to make rimraf a dependency of web3-providers-ws and have the script use the rimraf command instead of rm.

As for the npm bug I linked to earlier — it's a real thing over which web3 has no control and there's no easy way to get around it other than for users to upgrade their npm, sorry @taducquang. Maybe web3 1.x can switch to using a websocket version that's downloaded from the registry (change already made in web3 2.x), but I think there's still some problem whereby web3 1.x needs to install the version directly from github — it's the install from github that triggers the bug. Note that on linux/macOS using a github: specifier instead of git:// masks the bug (for reasons I don't know) but on Windows the bug shows up either way and the only fix I found is to use latest npm.

Can any one please help? can't install web3 on windows

[michaelsbradleyjr]

@sabby19 after discussing with @nivida the plan is to switch from the github: specifier that installs the websocket package from a fork on github to a version that will come from the NPM registry. The preinstall script that's causing problems on Windows will also be removed. Both changes will likely land together in a forthcoming release of web3 1.x.

In the meantime, you can install the Cmder bundle that includes Git for Windows. Also, you will need to upgrade to the latest npm (6.10.2 presently). When running npm install commands in a Cmder (+ Git for Windows) session the rm command should be available. And the upgraded npm will prevent your being affected by the npm bug re: dependencies installed from github:/git:// specifiers.
