Hi please execute bench update again after running the command

kdevloper · January 28, 2017, 9:03am

I have run bench update but I have same error

johnskywalker · January 28, 2017, 9:12am

How did you install your python before? Do you have python pre installed in your server at that time you first setup your server? Or you installed it by your own. Because as far as I can remember, I encountered somewhat similar to this error when I installed python libs wrongly

rmehta · January 28, 2017, 9:31am

This seems to be a problem!

kdevloper · January 28, 2017, 9:32am

Hello,
This is a working ERPNEXT instance.
I installed the it using the Easy Install Step. But It seems I made a Mistake using root user.
I tried to do some update but this time with frappe user, but I discovered there was file permission issue.
I ran the Linux command: “Sudo chown -R $USER:$USER bench-repo frappe-bench” to reset the permission to frappe user.

This caused so git problems, but I did a hard reset.

I tried bench update, but it failed.

kdevloper · January 28, 2017, 9:35am

How can I repair this,
On my Virtual Machine local instance, I noticed there is a file “pip” inside frappe-bench/env/bin/pip but It is missing on the Live server.
Should I copy this file over?
Are there some other files that could be missing too

navdeepghai · January 28, 2017, 12:04pm

When you’ll execute bench update it’ll also upgrade the pip in virtual env.
if there is version mismatch in /bin/pip and /home/frappe/frappe-bench/env/bin/pip then you’ll get this error while bench update.

Solution:
Try to upgrade pip manually:
Step 1 (System Environment) execute :
sudo /bin/pip install pip --upgrade
Step 2 (Python virtual Environment) Inside frappe-bench execute :
./env/bin/pip install pip --upgrade

Now again try to update your bench.

kdevloper · January 29, 2017, 5:26pm

I have tried this you solution but it did not work.
For Step 1: I run this command to see where pip is located on the system

frappe@erp:~$ pip show pip

STEP 2: Frappe-bench Directory Python Virtual

frappe@erp:~/frappe-bench$ ./env/bin/pip install pip --upgrade
bash: ./env/bin/pip: No such file or directory

Actually the pip fill is missing on the /home/frappe/frappe-bench/env/bin/

navdeepghai · January 29, 2017, 6:19pm

Ohkay got it!

Reason why pip doesn’t exists inside virtual enviroment:
When you execute bench update, it automatically update your pip, but before updating its always required uninstalled your older pip version.Here unfortunately your pip version haven’t update and older has uninstalled.

So you’ve to install it manually in virtual environment:
Execute < ./env/bin/easy_install pip > inside frappe directory and try to upgrade pip in virtual environment and then try again with bench update to update bench.

Its Architecture related error.
you are trying to install 32 bit lib on your 64 bit Operation System.

Which type of ERPNext setup are you using ?
a) Virtual Image
b) Or trying to install on Linux using sudo python setup.py --user frappe --production or --develop .

kdevloper · January 30, 2017, 12:04pm

b) Ubuntu 14 production

kdevloper · January 30, 2017, 1:13pm

After re creating env as above
I have solved this problem. Using the following command

./env/bin/easy_install mysql-python

./env/bin/pip install -e ./apps/frappe
./env/bin/pip install -e ./apps/erpnext
./env/bin/pip install -e ./apps/shopping_cart

Then bench update

Resolved
Thanks everyone
