Go is already installed in my system.
and path variable is in .bashrc file.
# Golang
export PATH=$PATH:/usr/local/go/bin
$ go version
go version go1.16.14 linux/amd64
Now, I am willing to work with Beego and bee dev tools. For that, I installed Beego and Bee by using these commands.
$ go get -u github.com/beego/beego/v2
$ go get -u github.com/beego/bee/v2
both got successfully installed. but when I am using the command bee version it is resulting this in the Terminal.
Command 'bee' not found, did you mean:
command 'tee' from deb coreutils (8.30-3ubuntu2)
command 'see' from deb mime-support (3.64ubuntu1)
Try: sudo apt install <deb name>
I am a beginner in the programming world. I am not sure How to resolve it. Can Someone help me with this?
I had the same issue. When using the command bee is installed in home/go/bin. What I did was copy the bee file from there and paste it in usr/local/go/bin. Also I used go install instead of go get and at the end of the url I added the version I wanted, eg. #v2.0.2
You need to have GOPATH determination. If you don't, create a folder which named as go and it needs to have src,pkg,bin folders.
When you install successfully, you can see bee file in bin folder.
NOTE: You can see go environment with go env command.
I am trying to install Ruby on a remote server using rbenv.
However, when I run the command rbenv install 2.7.2, I get the error below:
ruby-build: TMPDIR=/tmp cannot hold executables (partition possibly mounted with noexec)
I have rbenv and other dependencies for the Ruby programming language properly installed.
After a few research and trials, I was able to solve it.
Here's how I solved it:
The issue was that the rbenv installer needed a directory to store temporary files while it is downloading and installing ruby, however, the /tmp directory which is the default directory for storing temporary files wasn't accessible by my current user.
I tried to change permissions for the /tmp directory to allow it become accessible to my current user, however, I was unsuccessful.
All I had to do was to create a new tmp directory in the home directory of my user:
mkdir ~/tmp
Next, I opened the .bashrc file in the home directory of my user:
sudo nano ~/.bashrc
Next, I added the line below to the bottom of the file and saved:
export TMPDIR="$HOME/tmp"
Finally, I restarted my terminal or ran the command below to load the newly added paths into my current shell/terminal session:
exec "$SHELL"
Now, I could run the command rbenv install 2.7.2 and it worked fine.
Resources: TMPDIR=/tmp cannot hold executables (partition possibly mounted with noexec)
Adding to the OP's answer, you don't need to create a new tmp folder. Only adding to the path should work as well.
For example, I'm trying to install pipenv using the following commands:
$ pip3 install --user pipenv
$ cd ~/Documents/myproject
$ pipenv install requests
zsh: command not found: pipenv
It seems that the issue can be resolved if I run sudo ln -s ~/.local/bin/pipenv /usr/bin. Is this a safe thing to do? I've also been having this issue with several other packages, like tensorboard and xflux. Is there something wrong with my system that makes it such that I need to manually create a symlink every time? How can I change things so that packages can install normally without me having to do this every time?
The problem you are having is that the tools you are installing are being installed in non-standard locations and are not being included in your PATH. One way to resolve this would be to include the paths in your PATH environment variable. In order for these programs to be in your path every time you login, do this (assuming you are using zsh as your shell):
1) Open ~/.zshrc using vim or any other editor:
vim ~/.zshrc
2) Append the following to this file:
export PATH=$PATH:/path/to/dir/containing/pipenv
Remember to replace /path/to/dir/containing/pipenv with the appropriate path.
3) Source your ~/.zshrc so that the path is included in your current session:
source ~/.zshrc
4) Now everytime you login, the paths should be available in your environment and you won't need to create symlinks.
I use v0.6, but certain packages do not function with v0.6 (such as Interact.jl). How can I install v0.5? I am running Ubuntu 16.04.
First we have to download the latest Julia version from https://julialang.org/downloads/
I used the “Generic Linux Binaries for x86” version. The choice between x86 and ARM depends on the processor of your machine. Also choose between 32 bit and 64 bit versions based on the operating system and processor you have on your machine.
After download, you will get a compressed tar.gz archive having name similar to “julia-0.6.2-linux-x86_64.tar.gz”. As the “julia-0.6.2-linux-x86_64.tar.gz” name suggests that I downloaded the Julia version 0.6.2 which is latest at the time of writing this.
The names may differ. Adapt the names accordingly.
Remember these are binaries, these don't need to be installed as they can be directly used from the directory they are extracted.
I am assuming that the downloaded file is in your ~/Downloads directory of Ubuntu.
Open the terminal and navigate to the directory where the downloaded tar.gz file is stored, in present case the Downloads directory.
The terminal when just opened will show:
x#xpc:~$
where x should be replaced by your username and xpc should be replaced by your computer name.
Navigate to the Downloads directory using cd Downloads and then press Enter to get following terminal:
x#xpc:~/Downloads $
Extract the tar.gz file using the command
tar -zxvf julia-0.6.2-linux-x86_64.tar.gz
Now a directory with extracted contents will be generated in the same parent directory as of the compressed archive with a name similar to julia-xxxxxxxxxx where xxxxxxxxxx may be a combination of alphabets and numerals.
This is the final directory you need to run the latest Julia version, no installation is needed.
To run Julia, you can directly run using the julia file in location julia-xxxxxxxxxx/bin/julia as discussed below.
Navigate to the bin directory in the extracted directory using
cd /Downloads/julia-xxxxxxxxxx/bin
The terminal will now be like:
x#xpc:~/Downloads/julia-xxxxxxxxxx/bin $
Now run the command ./julia to run julia on the terminal as shown below.
The terminal will now change to julia as presented below. I know the representation is little different here as this is all I can manage to copy from the terminal to present it to you.
julia>
But the problem is that I have to navigate to the directory every time to run Julia.
Many people have discussed on the internet about defining the path and alias through very complex procedures and as I am not a hardcore computer geek, it was really difficult for me to understand.
I came to know about making a soft link.
So I decided to make a soft link to the Julia to run it directly from anywhere with a short command without navigating to the directory containing it.
I always try to do things neatly, so I decided to keep the extracted directory named julia-xxxxxxxxxx in the /opt directory of my system as most of my important programs reside in that.
You need root permissions to copy a file into the /opt directory, so I used the command sudo su and then provided password to get the super user privileges:
x#xpc:~$ sudo su
[sudo] password for x:
root#xpc:/home/x#
Now navigate to the directory presently containing the extracted directory:
root#xpc:/home/x# cd /Downloads/
root#xpc:/home/x/Downloads#
Copy the directory using:
root#xpc:/home/x/Downloads# cp -r julia-xxxxxxxxxx /opt
After the directory is copied to the destination, now we will make the soft link in a directory which is in the system path so that the soft-link can be called from any location to run Julia.
To find out the directories in the system PATH use echo $PATH, you will get a list of paths of directories separated by colon(:) such as /usr/local/bin. You can use any of them. I used /usr/local/bin for the soft link.
Navigate to the chosen folder.
root#xpc:/home/x# cd /usr/local/bin
The terminal will become
root#xpc:/home/x/usr/local/bin#
Create the soft link using
root#xpc:/home/x/usr/local/bin# sudo ln -s /opt/julia-xxxxxxxxxx/bin/julia julia
Now return to the normal user terminal using the keyboard combination Ctrl+D at the empty terminal root#xpc:/home/x/usr/local/bin#.
The terminal prompt will become:
x#xpc:~$
Type the newly made soft link i.e. julia in the terminal as shown below
x#xpc:~$ julia
This is where the magic happens and you get this:
julia>
The instructions can be used for any version of Julia in Ubuntu.

Firstly, you should really read the post that Reza Afzalan linked. It gives you everything you need to know about how to install. If you prefer a list:
Go to the Julia download page.
Download the Generic Linux Binary for your OS (probably 64-bit for Ubuntu 16).
Install it.
Find where the installed Julia binary executables are stored on your machine.
Symlink Julia v0.5 and Julia v0.6 to different aliases, e.g. julia5 and julia6. You can store the symlinks in a directory like /usr/local/bin.
Open julia5.
Start downloading your packages with Pkg.add.
It's very easy, here's how to install it on Linux in 8 steps:
1- go to Julia downloads page
2- Choose you version (32bit or 64bit) from Generic Linux Binaries, and then download it.
3- extract .tar.gz file in home or any place you would like to install Julia on it.
4- run > gksudo gedit /etc/environment on your terminal to setup envirnment path.
5- edit file :/Path_To_extracted_File/bin in my case it was like this:
":/home/okasha/julia-d386e40c17/bin"
6- Save edits and close the file.
7- Restart your machine.
8- Open your terminal again and run > julia -version
you shoud get "julia version 0.6.2" for Example according to your installed julia version.
Run > julia to open julia session.

Just type this
sudo apt install julia
I am trying to set up Laravels Valet (Valet is a Laravel development environment for Mac). Everything works until it comes to the command "valet install". This command must be executed in terminal. But I got the error "command not found". Any ideas, why? Do I have to update my PATH or something else?
I switched to OS X a few days ago. Before that, I was a windows user. So I am a total newbie.
Yes, you need to make sure that ~/.composer/vendor/bin directory is in your system's PATH, you can check this by running:
echo $PATH
If you can't see it there, then you need to add this to your ~/.bash_profile:
export PATH=$PATH:~/.composer/vendor/bin
If you're getting the error message "valet: command not found", it's likely that PHP's Composer is not in your PATH variable, for instance:
$ valet install
-bash: valet: command not found
You can confirm if Laravel Valet was successfully installed by running the following command:
ls -al ~/.composer/vendor/bin/valet
If successfull, you'll see the symlink for Valet in Composer's bin directory pointing to Laravel in the vendor directory:
~/.composer/vendor/bin/valet# -> ../laravel/valet/valet
To test whether your PATH is missing Composer, try running the Valet command directly:
~/.composer/vendor/bin/valet --version
If you're shown the Laravel version number, (e.g. Laravel Valet 2.0.4), this indicates Valet is installed but you need to update your PATH variable to include Composer for the valet command to work globally.
In your Terminal, execute the following command which will append Composer to your shell's PATH:
export PATH=$PATH:~/.composer/vendor/bin
For the changes to take effect, you'll need to exit and re-open your Terminal window or tab.
Alternatively, you can simply source your shell's profile, which doesn't require quitting your active session:
source ~/.bash_profile
If you have a different shell environment or you're using a shell other than Bash, you will need to source its configuration profile instead (e.g. .bashrc, .zshrc, config.fish).
I'm using oh-my-zsh so:
echo "export PATH=$PATH:$HOME/.config/composer/vendor/bin" >> ~/.zshrc
source ~/.zshrc
You may replace .zshrc with .bashrc
you just have to use:
export PATH="$PATH:$HOME/.composer/vendor/bin"
then
valet install
ready :)
Make sure that ~/.composer/vendor/bin directory is in your system's PATH, you can check this by running:
echo $PATH
If not there, open your ~/.bash_profile and add this code:
export PATH=$PATH:~/.composer/vendor/bin
Then run:
composer global require laravel/valet --dev
Once it is done, run:
valet install
If valet install doesn’t work, but ~/.composer/vendor/bin/valet --version does work, try installing it via
~/.composer/vendor/bin/valet install
To See if that worked, check
valet --version
If you're using zsh, you cannot use ~ as path to home dir, use $HOME instead.
In .zshrc file, instead of adding this:
export PATH=$PATH:~/.composer/vendor/bin
Add this and the path will resolve:
export PATH=$PATH:$HOME/.composer/vendor/bin
If you have a fresh installation, you may not have the PATH variable contains your home path. So, adding the $HOME variable would require like the following:
export PATH="$PATH:$HOME/.composer/vendor/bin
This command might solve your problem
test -d ~/.composer && bash ~/.composer/vendor/bin/valet install || bash ~/.config/composer/vendor/bin/valet install
In Ubuntu 18.04 do this:
echo "export PATH=$PATH:$HOME/.config/composer/vendor/bin" >> ~/.bashrc
source ~/.bashrc
with new composer installation, you need to add a new path which is
export PATH=$PATH:~/.config/composer/vendor/bin
Then you need to
chown YOUR_USERNAME ~/.config
for accessing composer packages without sudo command.
I have installed Composer version 2 and found that composer default path is ~/.config/composer/ and similarly valet is also installed on /.config/composer/vendor/bin/valet.
So to solve this issues I added the composer path to ~/.bashrc file as:
export PATH=$PATH:~/.config/composer/vendor/bin
Add ~/.composer/vendor/bin directory to your PATH variable.
For me worked
write in console
cd ~/.composer/vendor/bin
pwd
copy pwd command result
export PATH=$PATH: (pwd command result)
valet install
I think I explained well
I found a fix on this website, and it fixed my issue.
test -d ~/.composer && bash ~/.composer/vendor/bin/valet install || bash ~/.config/composer/vendor/bin/valet install
https://hidayatabisena.medium.com/solving-issues-command-not-found-laravel-valet-install-on-macos-mojave-2a7629759a9f
In my case I've to update /etc/profile file
added
export PATH=$PATH:~/.composer/vendor/bin
in
/etc/profile
then
source ~/etc/profile
In my case I found the valet location by manual search
Then add the the valet file path to PATH variable
echo 'export PATH="$PATH:$HOME/.config/composer/vendor/bin"' >> ~/.bashrc
Then I ran the install command and it worked
valet install
Php may be not installed
Use your prefered version with:
brew install php
// or
brew install php#8.0
// or
brew install php#7.4
This solved my issue.
