Merged with strange permissions problems for virtualenv python executable (lubuntu-12.10).
I installed virtualenv-1.7.1.2 on python-2.7 using pip-1.0.2.
when I run the command
$sudo virtualenv --distribute .
it raises the following error
ERROR: The executable ./bin/python2.7 could not be run: [Errno 13] Permission denied
can anyone help?!!

I am running Ubuntu 16.04 with Xilinx Petalinux 2018.03 SDK. After a number of successful compilations I am now facing this error
$ petalinux-build
[INFO] building project
[INFO] sourcing bitbake
ERROR: Failed to source bitbake
ERROR: Failed to build project
How can I solved this issue?
Another reason to get the errors "ERROR: Failed to source bitbake" as well as "ERROR: Failed to build project" is a possible upgrade of Python on the build machine. The Petalinux SDK requires python v2 (>= 2.7.3) for the 2018.3 edition.
You can check under [YOUR_PROJECT]/build/build.log and you might see a log similar to this one below:
[INFO] building project
[INFO] sourcing bitbake
SDK environment now set up; additionally you may now run devtool to perform development tasks.
Run devtool --help for further details.
OpenEmbedded requires 'python' to be python v2 (>= 2.7.3), not python v3.
Please set up python v2 as your default 'python' interpreter.
ERROR: Failed to source bitbake
ERROR: Failed to build project
To remedy this issue remove the symbolic link under /usr/bin and make sure to create a new one that is pointing to Python 2.7:
sudo rm /usr/bin/python
sudo ln -s /usr/bin/python2.7 /usr/bin/python
First you need to investigate the error a little further, do this:
source /opt/pkg/petalinux/2018.3/settings.sh
It will return something similar to this below:
PetaLinux environment set to '/opt/pkg/petalinux/2018.3'
INFO: Checking free disk space
INFO: Checking installed tools
INFO: Checking installed development libraries
INFO: Checking network and other services
Source the environment setup:
source /opt/pkg/petalinux/2018.3/components/yocto/source/aarch64/environment-setup-aarch64-xilinx-linux
followed by:
devtool --help
In my case I can see more about the actual error:

This is pointing to the /proc/sys/fs/inotify/max_user_instances that need to be increased. In my case I went from 128 to 256 by doing this:
sudo su
echo 256 > /proc/sys/fs/inotify/max_user_instances
You need to become root with "su" and change the mac_user_instances.
I want to setup a private tangle on my own virtual machine with Ubuntu 18.04, 4GB RAM and 20GB memory.
I have follow this instructions: https://docs.iota.org/docs/compass/0.1/how-to-guides/set-up-a-private-tangle. Every command works fine until reach this one: bazel run //docker:layers_calculator.
It shows an error as follows:
Starting local Bazel server and connecting to it...

How can I solve this problem? what I have missed?
read carefully the message given after running bazel installer:
Make sure you have "/home/yourusername/bin" in your path. You can also activate bash completion by adding the following line to your :
source /home/yourusername/.bazel/bin/bazel-complete.bash
You can check with: "bazel info" or "bazel version"
Unfortunately, there are further errors:
https://github.com/iotaledger/compass/issues/142
I have solve this issue by using this commands:
Step 3: Set up your environment
If you ran the Bazel installer with the --user flag as above, the Bazel executable is installed in your $HOME/bin directory. It’s a good idea to add this directory to your default paths, as follows:
export PATH="$PATH:$HOME/bin"
You can also add this command to your ~/.bashrc or ~/.zshrc file to make it permanent.

I'm setting up a project inside veracrypt and it's throwing this error when I try to setup the environment.

I've tried to look for the source of the issue and it seems it's related to how it's a virtualdrive with limited rights
admin#kali:/media/veracrypt1$ ln -s testfile

Looks like you are running this in an environment with limited permissions.
Some report this behavior when running on Linux,
but in a folder that is mounted to a "FAT32" partition -
see Chris Lope's blog-post:
permissionerror: [errno 1] operation not permitted
I have experienced this behavior while running in an Ubuntu VM
in a folder that was mounted to the host-OS (Windows-NTFS) as type 'vboxsf'.
Solved it by moving to work in a partition that is native Unix.
I need to install robotframework-autoitlibrary to use on my test cases.
My problem is when I try to install AutoIt Library through command line with the following command:
pip install -U robotframework-autoitlibrary --no-cache-dir --pre
I have this error:

Thanks for your help,
The error looks like the environment variable HOMEDRIVE is not set, even though it has a value according to your test (the library installer uses it to copy some files).
Can you try this - manually set it, and straight after that run the pip - in the same Command Prompt (cmd) session:
set HOMEDRIVE=C:
pip install -U robotframework-autoitlibrary --no-cache-dir --pre
I'm getting this error when trying to compile
lessc: ENOENT, open '/Users/William/Desktop/websites/grace/agency.less'
I'm using a MAC I've tried
$ lessc agency.less > agency.css & sudo lessc agency.less
same error. What am I doing wrong?
