I want to create an application on Frappe for garments manufacturing company. I ended up at Apprelo.

Apprelo

Is an application created on Frappe, which is used with ERPNext. Source

Setting up Apprelo

Installing Apprelo app on my local bench:

$ bench init apprelo-bench

This Apprelo is very old project. Last commit is 3 years ago. Will face issues definitely.

After creating the bench

$ cd apprelo-bench

Create a site inside the bench

$ bench new-site site.name
$ bench get-app erpnext https://github.com/frappe/erpnext.git
$ bench --site [site-name] install-app erpnext

Add the site link to hosts file too

$ bench --site site.name add-to-hosts

After installing erpnext, complete the setup wizard (need to be done before installing apparelo, as apparelo requires the entries made at the time of setup) and do the following

Install Apparelo App

$ bench get-app apparelo https://github.com/aerele/apparelo.git
$ bench --site [site-name] install-app apparelo

Error:

This Apprelo apps was created for ERPNext Version 12 and I am installing it along ERPNext 15. That’s the reason it is giving error.

I have called Apprelo developers too for support. Let’s see if they revert to my mail. Though this above info is provided by them only.

Turnaround solution:

Install Old:

• Bench
• Frappe
• ERPNext Then Install apprelo

$ pip install frappe-bench==5.0.0

I have downgraded the bench.

Error

After running

$ bench --version

Downgrading the markupsafe package

$ pip uninstall markupsafe
Found existing installation: MarkupSafe 2.1.3
ERROR: Cannot uninstall MarkupSafe 2.1.3, RECORD file not found. Hint: The package was installed by rpm.

To solve the error, run the pip install markupsafe==2.0.1 command to install the last version of markupsafe that supports soft_unicode. From here

Now install bench 5.0.0

Still old version of bench facing error while creating bench.

Install specific version of erpnext

$ bench get-app --branch version-14 erpnext

Install

1. Bench

$ bench init test

2. Frappe

This will install latest version of Frappe too.

• Create a site

$ bench new-site site.name
$ bench --site site.name add-to-hosts

3. ERPNext v12

$ bench get-app --branch version-12 erpnext

4. Apprelo

Error:
