I've been using Cypress locally on my MacBook for some time and it's been going great. Lately my device has been having trouble, so I set up WSL on my PC so I could have a backup in case the worst were to happen.
We use yarn to handle dependencies, and I used NPM to install Cypress and Yarn.
Originally everything I was installing was going into a mounted virtual drive, where nothing was working. I eventually got it running off the linux directory, and Yarn and the dependencies installed fine. I also was able to install Cypress#9.5.4, which is the current version I'm using.
Every time I try to run Cypress headed or headless, I'm being met with the following:
No version of Cypress is installed in: /home/workterminal/.cache/Cypress/9.5.4/Cypress
Please reinstall Cypress by running: cypress install
----------
Cypress executable not found at: /home/workterminal/.cache/Cypress/9.5.4/Cypress/Cypress
----------
A couple coworkers took a stab at it, and this is as far as we could get before I decided to reach out for help here. We got me off the mounted virtual drive, we got NPM and Yarn installed properly after using the linux directory, and then reinstalled Cypress using yarn add cypress#9.5.4, which completed successfully.
We've tried expanding $PATH to include everywhere where Cypress exists, but it always looks in .cache. What can I do to toubleshoot further?
I'm trying to get an electron forge app running on my Windows 10 machine via Linux on windows (using the new built-in windows bash functionality).
When running electron-forge start I am getting back the error message:
[1484:1126/222326.466455:FATAL:setuid_sandbox_host.cc(157)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /mnt/c/.../node_modules/electron/dist/chrome-sandbox is owned by root and has mode 4755.
From some searching, this thread on the electron Github makes it pretty clear that this is somewhat by design and the way to get around it is to run chmod as a root user post-installing all of the dependencies.
I attempted to do this and the command looked like it had worked (no error on running the chmod to 4755), but that didn't fix running electron-forge start - I still got the same error message. I looked into that a bit and it seems that this has to do with what files the linux subsystem are allowed to control permissions for per this Microsoft thread.
Is there some other trick to getting electron forge to work with bash on Windows?
I found that running the electron-forge init from Windows powershell into a native Windows directory allowed me to subsequently use npm start in my-app (for example) in WSL. So ultimately what I ran was
powershell npx create-electron-app my-app
(I have alias powershell="/mnt/c/windows/system32/WindowsPowerShell/v1.0/powershell.exe" in my .bashrc file)
I'm having a very strange issue:
Working on a project, which is a monorepo managed with lerna, I am unable to run tests for some reason unless I use sudo. I know it is not a project configuration issue, because no one else on my team is experiencing this problem.
The error, which is thrown immediately, ends up being:
Jest encountered an unexpected token
...
/Users/jasmar/dev/project/src/__setup__/setupTest.js:1
({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,global,jest){import { configure } from 'enzyme';
My environment is:
Mac OS X High Sierra
yarn (installed via brew)
Node 8.10.0 (via nvm; installed via curl)
I am an admin on the machine and have run sudo chmod -R ug+w . against the project directory to no avail.
I've also tried npm run test to no avail.
The test script that yarn runs is FORCE_COLOR=1 lerna --concurrency=4 run test and I have tried dropping concurrency to 1.
While running sudo yarn test does work, it is problematic as it generates new snapshots with incorrect permissions and makes managing version control extremely difficult.
Any ideas would be hugely appreciated.
Thanks!

I'm new to Selenium webdriver but the issue that I am running into does not seem like a common problem (looked everywhere for solutions for 4+ hours).
macOS High Sierra 10.13.2 - Selenium 3.13.0 [via pip3] -
ChromeDriver 2.40 [via web source] - Chrome 68 - Python 3.7
Here's what happened:
Initially chromedriver is in my Applications directory with .bashrc and .bash_profile including:
export PATH="$PATH:/usr/local/Cellar/python/3.7.0/bin:/Applications"
I was building a scraper in Python 3.7 everything is working fine executing from command line:
python3.7 scraper.py
I want to start running scraper.py from inside SublimeText3.
I copy chromedriver into /usr/local/Cellar/python/3.7.0/bin to be available for my python3 Sublime build system.
Doesn't work: something to do with it not being the original.
Accidentally deleted original.... So I remove all traces of chromedriver and redownload to Applications directory (original working conditions).
Now, I try to run again from command line and I'm getting Only local connections are allowed.
I try to execute chromedriver on the command line and I get bash: command not found. Even when I am in the Applications directory! Whereas before I could execute chromedriver from any directory.
Every solution online suggests that it's either a compatibility issue or a PATH issue but neither is the case.
Tried rebooting my system, reinstalling python, reinstalling Selenium, reinstalling chromedriver again, moving chromedriver/redirecting PATH, rebooting my system again, everything...
Any input would be greatly appreciated. I'm thinking it has more to do with the OS then anything else. But can't make heads or tails of this. Also wondering if using a virtualenv would be able to circumvent this issue?
UPDATE: To anyone experiencing a similar issue, I would recommend just using a virtualenv. This allows you to work in an isolated python environment without having to clutter up your system with global packages and potentially risking a bug in your system's configuration.
I'm interested in web development on the Node.js platform. My host OS is Windows 7. What would be the preferd way to set up a development environment. Run it directly on the host or in a linux based virtual machine? What are the pros and cons between these two methods?
If I go with a VM, can I still run the text editor and web browser in Windows (for performance reasons)?
Eh from experience, use Linux Docker.
edit Use Docker. bake in your dependencies, mount your project at run time, pin to a particular version of LTS node only. I'd take a 2gb docker image over un-runnable project leading to days lost being forced to upgrade to new packages. - 2018/04/10
But from someone whose spent the last 8 years developing in a linux based environment, and having spent the last 6 months developing software using nodejs in a windows dot net environment, here are my discoveries, shocking or otherwise...
Problems on windows:
can't effectively utilise docker Latest version of the docker toolkit solves this as far as I'm concerned. ymmv.
most node modules require node_gyp, which on the surface doesn't seem problematic (since gyp is supposed to be cross platform compiler), except when you delve into what it takes to get this working on windows: nothing short of installing visual studio will work. This sucks for me due to several reasons:
I'm normally on linux, so I never want to have to use visual studio.
It's entirely the most ridiculous idea that compiling something on windows requires at minimum a 3GB installation of an IDE... not libs but an entirely monolithic piece of GUI software I'll never ever launch.
the windows equivalent of debians build-essentials is actually a disparate sprawling ill named collection of gui only installers scattered across the internet all requiring a specific installation sequence. This, compared to sudo apt-get install build-essentials is overly time consuming and fraught with hidden gotchas.
developing on windows will allow you the bad habit of mixed case path names, unless your team either has a strict policy that is followed/enforced this will be a slippery slope to problems later on.
while windows supports more than 256 characters in paths, important tooling through out does not. enter stage left: rimraf and robocopy... ugh.
the windows terminal sucks... so does the default shell: cmd.exe...
Powershell is far too verbose in it's syntax and not to my taste... Installing Cmder aleviates this somewhat, however the only way for Cmder to interface with cmd.exe is to basically copy keystrokes to a hidden windows terminal running cmd.exe. (lolwut). Cmder works a lot better with shells that a more modular (zsh, bash, etc).. update: I now use powershell with pshazz and scoop, which is actually pleasant to use.
Having still improved the shell and terminal situation, nodejs for
windows will still assume your environment variables are %OF% %THE%
%WINDOWS% %VARIETY%... not the $UNIX $STYLE. So you'll basically be
using bower and npm mostly from cmd.exe... more ugh. I dont' seem to be having this issue anymore since I've incorporated a mix of cross-env and commander or yargs.
You'll also need to install python for windows, not a problem because choco exists and has you back there. update: have a look at boxstarter, will help automate your new machine setup with recipes (or you could actually graduate to using ansible or salt).
experienced python, ruby developers will tell you that old projects will need the version of their engine silo'd for when you need to revisit them (upgrading to newer versions is mostly not expedient or practical, read: rabbit holes), so you'll want something like rvm and virtualenv...
nvm (which only works on unix systems linux and macosx) because it's
a collection of bash scripts. I recommend using ZSH as your shell along with Zgen and Tarrasch/zsh-autoenv plugin.
nodeenv, which is more likely... a python program that integrates with virtualenv. Some people like this. I have no problem with it, but our team uses nvm.
however, you're better off with nvm-windows because "reasons". scratch that, use nodist on windows... bar far the better choice, you won't need to worry about some kind of autoenv since nodist by design handles this.
Installing on Windows:
install chocolatey
choco install cmder nodejs python2 choco install python2
install http://scoop.sh, then use it to install pshazz.
remove any versions of node manually installed globally.
install nvm-windows install nodist.
install visual-studio 2012 express, then never launch it if you treasure your cpu cycles. this may be overkill as microsoft have released an equivalent to build-essentials.
install windows 7/10 64bit sdk
Problems on Linux:
tldr; use nvm. for more reasons other than the below.
you'll have to set the global npm node_modules path to a user owned directory (I've started using ~/.local/share/npm). Pleasantly, this is something I found the windows installation of nodejs got right (probably not intentionally). A non issue when using nvm.
Ubuntu already has a binary called node, so #!/usr/bin/env node will by default not run nodejs. luckily debian systems have a neat management tool for controlling what the env binary emits: update-alternatives. ignore suggestions to use symlinks here, which will only cause problems later on in subtle ways. also a non issue when using nvm.
Installing on Linux :
$ sudo apt-get install git-core git-flow build-essentials python-dev python- pip
$ curl https://raw.githubusercontent.com/creationix/nvm/v0.20.0/install.sh | bash
$ npm config set prefix ~/.local/share/npm
$ nvm install stable
$ nvm alias default stable

We have a system via which we just use a config file, which handles all our problems like path differences ("c:\blarg" vs "~user/blarg") and, as a bonus, lets us control differences between debug and production environments.
Node.js is cross platform, so we totally have developers working on all sorts of computers, and it's no problem at all.
This is an example config file I use on a file storage project:
/**
* All of these are mandatory except for log_level (which defaults to "info", 1)
* and log_echo_to_console (which defaults to false)
*/
exports.config = {
log_level: 0,
log_file: "/path/to/send.log",
request_log_file: "/path/to/send_requests.log",
log_echo_to_console: true,
port_number: 8088,
no_notification_emails: true,
image_url_base: "http://s3.amazonaws.com/", // MAKE SURE THIS ENDS IN "/"
tmp_file_folder:"/tmp/",
s3_info: {
key: 'xxxxxx',
secret: 'yyyyy',
file_bucket: 'sendtransfer/',
},
backend_info: {
db_info: {
server: "localhost",
user: "db_user",
password: "secret",
database: "SendRemote",
pooled_connections: 125,
idle_timeout_millis: 30000
},
memcache_info: {
host: "127.0.0.1",
port: "31111",
pooled_connections: 200,
timeout: 20000
}
},
debug_server: true
};
For Windows machines, just change the paths. It's all good!
Then in code, you can just type:
var local = require('local.config.js');
fs.writeFile(local.config.log_file);
// etc
Embrace multiculturalism!!!
I am also on Windows 7 and use Virtualbox with a Linux ( debian ) guest, i would recommand it because I for myself am faster doing some stuff in the commandline then clicking arround in Windows.
Another nice feature is that if you put your VM on an USB stick you can take it with you and use it everywhere where a Virtualbox Host is installed, so you can take your whole development environment with you.
It's no problem at all to use your favourite text editor or browser in Windows, just install samba and mount your home directory into Windows.
Same goes for your browser since the VM is just another machine in your LAN, instead of pointing your browser to localhost point it to the VMs Ip and you are fine.
Obvious con here is if you don't have any experience with Linux yet you should probably stick to windows because it will take you some time to get into it.
just my two cents maybe even less:
I'll suggest you a third option: to double install windows/ubuntu setup (preferably ubuntu dist which is most gui friendly) and research this option as well this way you would be more familiar with the linux/unix and even iOS which will even make you understand windows better and a better programmer. Sometimes the virtual box is too slow, while linux is very efficient with resources.
If you have the ability to install a virtual machine,you can also give a go to installing a linux distribution and get yourself familiar with this language/system of OS which a lot of the web is structured upon
I really enjoy coding node.js on windows using git bash:

It's seems faster then and easier then running VirtualBox. Given that I still use Virtual Box for testing before going to production.
