Error: Cannot find module 'portfinder' when doing any ng commands #1782

zjkipping · 2016-08-20T23:02:40Z

I am currently using Windows 10 on this device, same as my laptop which doesn't seem to be having issues with the cli. I also have npm version 3.10.6 and nodejs version 6.4.0. I am running the command prompt in Administrator mode if that's makes a difference.

Regrettably like stated in the title I cannot run any angular-cli commands without the error, including "--version", but I did install angular-cli@webpack with npm. I also haven't started creating an app yet on this device due to this error.

Log from command prompt: (same error on everything command)

$ ng --version
(node:11820) fs: re-evaluating native module sources is not supported. If you are using the graceful-fs module, please update it to a more recent version.

I have tried solutions from these: Angular2 : Need to create angular2 folder structure using latest angularCLI Webpack
and Error: Cannot find module 'portfinder' with Webpack release and NPM 2 #1770 with no success and cannot seem to find anything else about this on google. Unlike the latter link, I do not care what version of npm I am using.

The text was updated successfully, but these errors were encountered:

filipesilva · 2016-08-23T14:30:35Z

I can't reproduce this on Windows 10 myself. It looks like your install is missing a package, which can be the result of a broken install or of a NPM upgrade without reinstall.

This should work if that's the case, but you say you've tried it already:

 npm uninstall -g angular-cli
 npm cache clean 
 npm install -g angular-cli@webpack

I'll leave the issue open in case there's a way to repro this I can use to debug.

web-dave · 2016-08-24T12:44:47Z

Same Problem here.
uninstall and install not solveing this.

If i run any ng command outside a cli Project it works fine.

$ ng v
angular-cli: 1.0.0-beta.11-webpack.2
node: 4.4.0
os: win32 x64

History:
I build a app with cli yesterday. Everything works fine.
Then I moved my files into a Project to push all to git.
clone this Project and run:
npm i
npm install --save-dev angular-cli@webpack
this throws error:

hmmpf

package.json says:

"typescript": "^2.0.0"

Why????

I Change it to
"typescript": "^1.8.10".
Next try

ng version works now
ng serve throws error:

run ng init
ng serve works. PUH! hard work.

dcavanagh · 2016-08-24T13:32:14Z

I am seeing the same or similar problem on mac. I have attached the npm debug file
npm-debug.txt

web-dave · 2016-08-25T09:23:29Z

I found (for me) followed solution:
Just short my last post.

clone project
npm i
npm install --save-dev angular-cli@webpack
ng init (no overwrite)

i find out that you need node v4.x to get it work, (had this problem with a team member)

regards

zjkipping · 2016-08-26T03:23:39Z

So I ended up taking a look at this again, since it would be preferable if I could get my desktop to run angular-cli vs my laptop.

I went ahead and uninstalled nodejs and wiped anything npm from appdata/roaming. Then installed the exact versions of Node.js (6.1.0) and npm (3.10.6) that my laptop has. Then attempting to install Angular-cli on the version of 1.0.0-beta.11-webpack.

I managed to watch the install closely this time and noticed some errors, that I haven't seen before on my laptop... Below are images of the errors

The first was an error then followed by a ton of warnings, that I have never noticed

The second is a much larger error

Still ending up with the same 'portfinder' error when I attempt ANY ng commands, such as just typing ng by itself and hitting enter, ng init, ng new test_prog, ng -v, etc...

bbohling · 2016-08-27T16:02:50Z

So I had this same issue during a project upgrade and resolved by going through a few hoops...

First off I was using an LTS version of node (v4.x with npm v2.x) which resulted in the portfinder error
I then tried to update to the latest LTS version, but still failed
Succumbed to the fact that the pre-reqs are true I used nvm to install the latest node 6.x and npm 3.x
I performed the uninstall and cache clean steps
This time I got a different error: could not find module config-chain
Following the instructions in Cannot find module 'exists-sync' #1186 I navigated to my local (project) instance of node_modules/angular-cli/ and ran npm install
Ran ng init with no issues

zjkipping · 2016-08-27T18:11:53Z

@bbohling Did something similar to what you suggested, as I don't even have a project created yet since I cannot run any commands. I went to where my angular-cli was installed globally, appdata/roaming/npm/node_modules, and ran npm install there. Unfortunately I still get the above npm install errors and the portfinder error outlined in the images of my previous comment...

bbohling · 2016-08-27T18:29:58Z

Sorry @zjkipping I should have explicitly stated that I navigated not to the global angular-cli instance, but my local (project) instance.

retallicka · 2016-09-07T10:29:18Z

I got the same problem and I solved the issue for me by going to my angular-cli folder and installing portfinder there with npm install portfinder it's working now but not sure why I got the error. My colleagues have a very similar setup (mac, node 6.5.0, npm 3.10.6) and they didn't get this error.

I can reproduce this by wiping angular-cli or node modules and reinstalling

jodytate · 2016-09-09T18:06:47Z

If a local npm install portfinder fails to fix the issue, a global install of portfinder works.

zjkipping · 2016-09-11T00:24:48Z

Thank @retallicka and @jodytate for the very helpful answers. This seems to have done the trick for me. I can now run ng perfectly fine outside of another older angular-cli webpack project. I believe this problem is just that I am now on a newer version of the cli (beta.11-webpack.8) vs when I created it in the early days of beta.11-webpack.2. I'll go ahead and close this since my issues have been resolved.

foaudkajj · 2016-09-18T18:33:07Z

Worked for me thanks 👍
cd your_project_folder
Then :
npm install --save-dev angular-cli@webpack
ng init

mohammedzamakhan · 2016-10-10T18:31:33Z

@retallicka @jodytate followed both steps, but doesn't works on my MAC

damoqiongqiu · 2016-10-26T12:49:20Z

@jodytate
npm install portfinder solved the problem on my MAC.

rocky-bgta · 2016-11-02T14:34:49Z

Please install those dependence manually such as reflect-metadata and portfinder globally.
