“Incorrect header check” suggests that either the archive file that is generated (and which contains the app code) is invalid, or there’s an issue with the HTTP response compression. Both issues are very strange (but I don’t use Windows so don’t know if it’s a generic Windows issue, or it has something to do with your specific setup). ---

My homey is Brand new and nearly blank. Only some Apps are installated, no flows are created… So maybe, i think there is an incompatibility between Mapulo Devolo App - and homey firmware version. Github file is older… ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/c/7c8c0be603c1e46b545b0d1de5722ad6f2fa59cb.jpeg) Did anyone have a idea? Maybe i will ask Mapulo… ---

Looks like you’re using a proxy or a firewall that’s blocking access to the NPM repository. ---

Thanks @robertklep it was my firewall. I had to uninstall… Now it worked untill I want to install the devolo app: I unpacked the files to the desktop. What could be wrong?? Do I have to rename the file, or type the name of the file in the cmd? ![grafik](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/f/2/f2b0b69d81aaeba1f1acdfc868e9ecfe55a4e4b0.png) thanks! ---

Hi all, I think something whent wrong somewhere. Getting this message. What could be wrong? Already installed it, but didn’t work so i removed it and installed it again. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/e/8/e8b5776ab4af3a763fd7bf9ef44e5ac209d9c6f1.png) ---

Please follow the exact instructions [from the first post](https://community.homey.app/t/how-to-cli-install-method/198/1). The correct command is: ```auto npm install -g homey ``` ---

Hi @robertklep, I suppose you use a Mac, too, right? The CLI method and also the use of the terminal is new to me, but according to the information here, it should not be a problem. It shouldn’t be a problem… But… The installation of node.js (v. 14.8.0) worked without problems. But when I execute the command **npm install -g homey** I get some error messages because I don’t have the necessary write permissions. But I am logged in as admin. What can I do? I use macOS Catalina v. 10.15.6 (should this be relevant). ---

If you’re installing a module as admin, you need to add the `--unsafe-perms` flag: ```auto npm install -g --unsafe-perms homey ``` ---

Oh wait, you wrote _“But I am logged in as admin”_, and I assumed that you ran the `npm` command with `sudo`, but I guess you’re running it as a regular user (that also happens to be an admin). In that case, the best solution would be to change the ownership of the global `node_modules` directory to your user id: ```auto sudo chown -R $USER /usr/local/lib/node_modules ``` After that, you should be install to install global modules as a regular (admin) user (and you don’t need `--unsafe-perm`). ---

At least that’s what I thought. Something has changed, but I still don’t seem to have write access, at least not to the named files. ``` Dirks-MacBook-Pro:~ goebeldi$ npm install -g homey npm ERR! code EACCES npm ERR! syscall symlink npm ERR! path ../lib/node_modules/homey/bin/homey.js npm ERR! dest /usr/local/bin/homey npm ERR! errno -13 npm ERR!

I found this [link](https://github.com/nodejs/node-gyp/blob/master/macOS_Catalina.md) on the official [nodejs.org](http://nodejs.org). If I understand it correctly, there are some problems with Catalina and node.js, right? However, the topics “programming” and “node.js” are a new world for me with lots of question marks. When you know what I mean. ---

Ah, you may have to change the ownership of `/usr/local/bin` as well: ```auto sudo chown -R $USER /usr/local/bin ``` I don’t use Catalina because of all the “enhancements” that are making life for users and developers much worse.
