[1.0.0b4] poetry run fails with FileNotFoundError #1567

MrGreenTea · 2019-11-11T09:27:06Z

I am on the latest Poetry version.
I have searched the issues of this repo and believe that this is not a duplicate.
If an exception occurs when executing a command, I executed it again in debug mode (-vvv option). poetry run -vvv does not change anything about the output
OS version and name: Linux x86_64 (Elementary OS)
Poetry version: 1.0.0b4

Issue

Running poetry run without additional argument fails with

[FileNotFoundError]
[Errno 2] No such file or directory

Executing poetry run pip list for example works fine. It's just with either no argument or when the first argument is not found as an executable.

The text was updated successfully, but these errors were encountered:

hoefling · 2019-11-11T15:00:04Z

Me also getting this error with the 1.0.0b4. Using double dashes is broken in the latest beta, e.g. poetry run -- pytest -svx --lf ends with the FileNotFoundError message.

I also getting this error after renaming the parent dir.
And it resolved by removing .venv dir and executing poetry install

JavierL1 · 2020-01-20T13:02:19Z

I also getting this error after renaming the parent dir.
And it resolved by removing .venv dir and poetry install

Can you give a little bit more feedback on how did you resolve the issue? You removed the poetry install command from execution?

taketarouex · 2020-01-20T13:32:23Z

I'm sorry. I was mistaken.
I intended to say that I removed .venv dir, after that I executed poetry install and I resolved it

JavierL1 · 2020-01-20T17:41:30Z

I just solved my problem. I used for reference this issue #1198.
In my case, I have a project that uses a CLI interface implemented with click. So in order to run a command using poetry, first I had to register the group of commands as a poetry script, just like it's described here.
I hope it helps you!

kiudee · 2020-08-03T12:43:38Z

Same problem here using 1.0.10 on Ubuntu 20.04.

poetry run --help

results in

[FileNotFoundError]
[Errno 2] No such file or directory

while poetry run python or poetry run pip works.

Related to #2741.

dector · 2020-08-17T14:28:44Z

I have this issue too.

This works:

technillogue · 2020-12-25T21:45:21Z

it would be awfully nice if poetry told you to run poetry install or something instead of just FileNotFoundError

mattwelke · 2021-01-12T18:51:12Z

I'm getting this error even after I run poetry install.

Steps to reproduce:

Create new Poetry project with poetry init.
Create file app.py with contents print('hello').
Run poetry run app.py.

Something I notice is that poetry can't run my program but using python directly can:

poetry run app.py 

  FileNotFoundError

  [Errno 2] No such file or directory

  at ~/.pyenv/versions/3.9.1/lib/python3.9/os.py:607 in _execvpe
       603│         path_list = map(fsencode, path_list)
       604│     for dir in path_list:
       605│         fullname = path.join(dir, file)
       606│         try:
    →  607│             exec_func(fullname, *argrest)
       608│         except (FileNotFoundError, NotADirectoryError) as e:
       609│             last_exc = e
       610│         except OSError as e:
       611│             last_exc = e

python app.py 
hello

EDIT:

Oh wait, I'm just stupid. I misunderstood how to use the poetry run command. Checking the docs helped me:

poetry run python app.py
hello

rourich · 2021-02-05T09:56:38Z

Me also getting this error with the 1.0.0b4. Using double dashes is broken in the latest beta, e.g. poetry run -- pytest -svx --lf ends with the FileNotFoundError message.

were you able to circumvent this problem?

Nathaniel-Rink · 2021-03-02T18:27:04Z

EDIT:

Oh wait, I'm just stupid. I misunderstood how to use the poetry run command. Checking the docs helped me:
poetry run python app.py
hello

This was immensely helpful. I'd misread the instructions too

joker234 · 2021-03-16T19:26:43Z

I have a similar error:

$ poetry run --no-ansi echo "hello"

  FileNotFoundError

  [Errno 2] No such file or directory

  at /usr/local/lib/python3.8/os.py:601 in _execvpe

       600│         try:
    →  601│             exec_func(fullname, *argrest)
       602│         except (FileNotFoundError, NotADirectoryError) as e:
       603│             last_exc = e
       604│         except OSError as e:
       605│             last_exc = e

or

$ poetry --no-ansi run echo "hello"
USAGE
  poetry help [<command1>] ... [<commandN>]

ARGUMENTS
  <command>              The command name

vs.

$ poetry run echo "hello"
hello

According to the help, I can use --no-ansi and --no-interaction with every poetry command. Where am I supposed to put them? The help isn't clear on that terms.

$ poetry help run
USAGE
  poetry run <args1> ... [<argsN>]

ARGUMENTS
  <args>                 The command and arguments/options to run.

Edit: some information on my system:

Tested within a python:3.8 docker container

NelsonAPenn · 2021-07-21T20:35:32Z

I get this error if I haven't properly added / installed a package within poetry. But the error is especially baffling in my case, because the directory it is trying to read from shouldn't be python related at all:

Below is some slightly censored output (just the file path censored) for if I run poetry run pytest without having first installed / added pytest.

poetry run pytest

  FileNotFoundError

  [Errno 2] No such file or directory: b'/path/to/my/godot/installation/godot-3.2.3/pytest'

       597│         path_list = map(fsencode, path_list)
       598│     for dir in path_list:
       599│         fullname = path.join(dir, file)
       600│         try:
    →  601│             exec_func(fullname, *argrest)

       604│         except OSError as e:
       605│             last_exc = e

I have no idea why poetry wants to look in the folder in which I installed godot, but it does, every time. Similarly:

 poetry run "the answer to life, the universe and everything"

gstravinskaite · 2021-09-24T08:47:25Z

I have the same issue as above, it tries to look to the Golang binaries to run Python program.

comalice · 2022-01-26T19:32:57Z

I have this same issue but it is looking for Perl binaries...

root@alatham <path to poetry project> (<virtualenv-name>) # poetry run

Note that I'm running from WSL2 on Arch Linux.

elyobo · 2022-02-04T09:22:00Z

Had the same problem, poetry install resolved it (even though nothing had changed 🤷‍♂️)

NelsonAPenn · 2022-02-20T23:53:50Z

In terms of the error message, it is raised during the call to os.execvpe. The reason the directory in the message is so weird in every case is because it is always the last path in the system path.

I think that the output of poetry run <command> could be much improved if it were to produce the same output that would appear if you ran poetry shell followed by <command> in the subshell. Running a nonexist command within poetry shell returns (on Ubuntu 20.04)


Command 'aoeu' not found, did you mean:

  command 'aoeui' from deb aoeui (1.7+20160302.git4e5dee9-2)

Try: sudo apt install <deb name>

which is kind of result you'd expect in this situation. I've looked into this a little and am not sure on the implementation details, but will create a PR if I come up with something I'm satisfied with.

branchvincent · 2022-02-27T06:10:25Z

Some of the UX issues around run have already been fixed on master:

$ poetry --version
Poetry (version 1.2.0a2)
$ poetry run

Not enough arguments (missing: "args")
$ poetry run --help

Description:
  Runs a command in the appropriate environment.
...
$ poetry run -vvv echo test
Loading configuration file /Users/Branch/Library/Application Support/pypoetry/config.toml
Using virtualenv: /Users/Branch/Code/python-poetry/poetry/.venv
test

I've filed #5243 to address the remaining cryptic FileNotFoundError when an executable isn't found

pkoch · 2022-03-18T19:29:01Z

Just got bit by this. In my case, I'd forgotten to run poetry install before poetry run pytest.

@1player that's not really a lot to work with. That might very well be something specific to your usage.

Can you make a repo with the minimum reproducible case for your problem?

1player · 2022-07-06T16:22:20Z

I literally just created a new repo with poetry init and ran poetry run. Running on Arch Linux.

pkoch · 2022-07-06T16:46:40Z

Indeed. Here's how I repro'ed it:

cd $(mktemp -d)

cat - > Dockerfile <<EOF
FROM archlinux

RUN pacman -Syyu --noconfirm python \
 && mkdir /code
WORKDIR /code
RUN (curl -sSL https://install.python-poetry.org | python3 -) \
 && /root/.local/bin/poetry init -n
EOF

# This takes a little while, give it time.
docker run --rm $(docker build -q .) /root/.local/bin/poetry run

dimbleby · 2022-07-06T17:36:51Z

On more recent versions of poetry you will see this:

$ poetry run

Not enough arguments (missing: "args")

which is a more helpful error message

pkoch · 2022-07-06T17:47:18Z

@dimbleby Can you name what's the version that starts happening? I've repo'ed @1player's problem with Poetry version 1.1.13.

dimbleby · 2022-07-06T17:54:03Z

no, I don't know where this changed. Try with the latest beta 1.2.0b2.

pkoch · 2022-07-06T18:00:35Z

Using curl -sSL https://install.python-poetry.org | python3 - --version "1.2.0b2", I do see that new error. 👌

NourKired · 2022-08-19T08:07:01Z

you have to add on you're pyproject.toml, this script:
example:
[tool.poetry.scripts]
converter-image-text = "converter_image_text.main:cli"
