Platformio-atom-ide: Serial Monitor: pio: command not found

[kalsan]

Atom: 1.15.0 x64 Linux
Platformio: IDE 2.0.0-beta.2 · Core 3.4.0a4

Steps to reproduce:
-> Press Serial Monitor
-> Select any port and baud rate
-> The following error occurs

pio device monitor --port /dev/ttyS0 --filter colorize --eol LF --echo
[me@laptop Directory] pio device monitor --port /dev/ttyS0 --filter colorize --eol LF --echo
bash: pio: command not found

(Build and Upload steps work fine though).

I am also seeing the same issue.

Atom: 1.15.0 x64 OSX
Platformio: IDE 2.0.0-beta.2.3 · Core 3.4.0a4

It also looks like when I open a Terminal the same bash: pio: command not found error occurs.

[tehnorm]

There seems to be a work around: https://github.com/platformio/platformio-atom-ide/issues/47#issuecomment-192302365

The path is different for the beta versions: Menu: PlatformIO > Settings > PlatformIO IDE Terminal > Auto Run Command and specify it to export PATH=export PATH=~/.platformio/penv/bin:$PATH

[kalsan]

@tehnorm thanks for sharing this workaround, it helps.

[ivankravets]

The problem is linked with customized .bash_profile. Please check that you don't override PATH variable. You need to keep previous value of PATH. For example, use

export PATH="/cusotm/paths:${PATH}"

instead of

export PATH="/cusotm/paths"

[kalsan]

Hmm, I don't actually override the PATH variable in bashrc or bash_profile.

In bashrc I simply have: export PATH=$PATH:'/home/sandro/.gem/ruby/2.3.0/bin'

And this is my acual path variable:

echo $PATH
/home/user/.gem/ruby/2.4.0/bin:/home/user/.gem/ruby/2.3.0/bin:/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/share/java/basex/bin:/usr/lib/jvm/default/bin:/opt/opencascade/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl:/home/user/.gem/ruby/2.3.0/bin

Why closing? The problem is not resolved, as stated in my comment on April 9th

[ivankravets]

@kalsan what is your shell?

[kalsan]

Thanks @ivankravets

I'm using bash on login. Sometimes I use fish, but it's unrelated to atom / platformio activities.

[ivankravets]

@kalsan what is your default shell? Could you check Fish initial configuration? Somewhere you override global $PATH.

[kalsan]

• My default shell is bash
• config.fish only contains a source with aliases
• fish handles paths specially: there is a $fish_user_paths which gets automatically prepended to the $PATH variable in fish. Digging through all configs, I can't find a single override.

When / how does platformio extend the PATH variable? Perhaps I can try to debug it this way.

[ivankravets]

@kalsan could you try this solution?

When / how does platformio extend the PATH variable? Perhaps I can try to debug it this way.

PIO IDE extends PATH with a path to PIO Core before starting a terminal instance. If you override PATH in your shell scripts, you will not see PIO Core here. You can try manually to make a few echo $PATH in different places.

[kalsan]

@kalsan could you try this solution?

My shell is already bash:
user@machine ~> echo $SHELL
/bin/bash
user@machine ~> sudo chsh -s /bin/bash user
[sudo] Passwort für user: 
Shell für user ändern.
chsh: Shell nicht geändert.

(Translation: "chsh: shell not changed")

I just installed the latest PlatformIO update. It didn't help.

This is what attempting to open a serial monitor looks like without the workaround linked by @tehnorm :

pio device monitor --port /dev/ttyS1 --filter colorize --eol LF --echo
[user@machine bitthief]$ pio device monitor --port /dev/ttyS1 --filter colorize --eol LF --echo
bash: pio: command not found
[user@machine bitthief]$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/share/java/basex/bin:/usr/lib/jvm/default/bin:/opt/opencascade/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr
/bin/core_perl:/home/user/.gem/ruby/2.3.0/bin
[user@machine bitthief]$

This is what happens if I apply the workaround:

export PATH=export PATH=~/.platformio/penv/bin:$PATH
pio device monitor --port /dev/ttyS1 --filter colorize --eol LF --echo
[user@machine bitthief]$ export PATH=export PATH=~/.platformio/penv/bin:$PATH
[user@machine bitthief]$ pio device monitor --port /dev/ttyS1 --filter colorize --eol LF --echo
--- Miniterm on /dev/ttyS1  9600,8,N,1 ---
--- Quit: Ctrl+C | Menu: Ctrl+T | Help: Ctrl+T followed by Ctrl+H ---
 
--- exit ---
[user@machine bitthief]$ echo $PATH
/home/user/.platformio/penv/bin:/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/share/java/basex/bin:/usr/lib/jvm/default/bin:/opt/opencascade/bin:/usr/bin/s
ite_perl:/usr/bin/vendor_perl:/usr/bin/core_perl:/home/user/.gem/ruby/2.3.0/bin

(Translation: "chsh: shell not changed")

You said that you have a fish shell, try to change to it and back to bash:

• http://georgik.rocks/workaround-failed-to-activate-the-platformio-ide-package/

---

Could you place this export PATH=~/.platformio/penv/bin:$PATH in your bash profile?

[kalsan]

@ivankravets here's a log of the experiments I did following your suggestions:

1. Changing shell

• Changing shell to /usr/bin/fish
  
  
  
  • pio works without the export workaround
  
  
• Changing shell back to '/bin/bash'
  
  
  
  • previous behaviour restored: 'pio: command not found'
  
  

2. Adding the penv path to .bashrc

• This is a valid workaround, works without the export workaround in the pio terminal settings

The second option would be an acceptable workaround for me, since it survives pio updates (unlike the previous export workaround). If you are satisfied with this solution as well, the issue can be closed in my opinion. However if you'd like to investigate further to get more insights and maybe find a potential bug, I'll be happy to assist.

Issue still exists in 2.0.0-rc2

[ghost]

Issue still exists in 2.0.0-rc4
Running Manjaro (Arch)

Fixed with: export PATH=export PATH=~/.platformio/penv/bin:$PATH added to ~/.bashrc

[VanKurt]

I have the same problem (just installed PlatformIO on macOS). When opening the serial monitor I get:

pio device monitor --port /dev/cu.SLAB_USBtoUART --baud 115200
Boriss-Air:RobotArm borisbrock$ pio device monitor --port /dev/cu.SLAB_USBtoUART --baud 115200
bash: pio: command not found

[VanKurt]

Any updates? I still can't work on my project because of this :-(

[ghost]

Does the use of the export command not work for you?

[ivankravets]

@VanKurt do you use a custom shell?

[VanKurt]

No, I don't use a custom shell.

To be honest I don't know what "~/.bashrc" is and how to add anything to it. So I didn't try the export command...

[ivankravets]

@VanKurt
Please provide an output from a system Terminal

echo $PATH
echo $PYTHONPATH
python --version
pip --version
pip list

[VanKurt]

Hi,
here's what I get:

Boriss-Air:~ boris$ echo $PATH
/Library/Frameworks/Python.framework/Versions/3.4/bin:/opt/local/bin:/opt/local/sbin:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/tools:/platform-tools
Boriss-Air:~ boris$ echo $PYTHONPATH

Boriss-Air:~ boris$ python --version
Python 2.7.10
Boriss-Air:~ boris$ pip --version
-bash: pip: command not found
Boriss-Air:~ boris$ pip list
-bash: pip: command not found

Could you try PlatformIO IDE for VSCode? Do you have the same issue?

• http://docs.platformio.org/en/latest/ide/vscode.html

[herm]

I also had this problem on a fresh install of Manjaro Linux (based on Arch). I did no customization wrt PATH. Compiling and programming works fine but serial monitor doesn't find pio. For me the soultion was to set Settings->Platform IO Terminal->Login shell to false. Probably somewhere in the systemwide config the path is overwritten for login shells.

[Sufomba]

Same problem with MX Linux, I did what 'herm' did and now it is working fine.

[dvera2004]

Hi,

For fix it, please make a symlink of pio to /bin

sudo ln -s /home/daniel/.platformio/penv/bin/pio /bin/pio

Works perfect.

Regards

[itsjimbo]

Setup bashrc path

echo "export PATH=~/.platformio/penv/bin:$PATH" >> ~/.bashrc
source .bashrc

Now test

cd my-platformio-project
pio run -t uploadfs

[ivankravets]

We have just released a new version 2.7.0, please upgrade.

Please note that we HIGHLY recommend moving to PlatformIO IDE for VSCode which resolves tons of issues and brings a lot of new features.
