When I install pyproj, pip returns error 127

[bluems]

OS: Raspbian latest version(Kernel 4.19.42)
Python: 3.6.8
Proj: 6.1.0

When I install pyproj, pip returns error 127.

Error Message:

subprocess.CalledProcessError: Command '['/usr/local/bin/proj']' returned non-zero exit status 127.

run sudo find / -name proj:

/usr/local/bin/proj

How do I install this?

Interesting, what happens when you execute /usr/local/bin/proj? Also, what are the permissions on /usr/local/bin/proj?

@snowman2

pi@raspberrypi:~ $ /usr/local/bin/proj
Rel. 6.1.0, May 15th, 2019
usage: proj [-bdeEfiIlmorsStTvVwW [args]] [+opt[=arg] ...] [file ...]

and

pi@raspberrypi:~ $ ls -al /usr/local/bin/proj
-rwxr-xr-x 1 root staff 150372 May 28 14:18 /usr/local/bin/proj

Currently, it works as normal.
The only action I have taken is to attempt to rebuild venv several times through PyCharm or virtualenv.

pip install -r requirements.txt

Run this from a python console:

import subprocess
proj_ver_bytes = subprocess.check_output(['/usr/local/bin/', 'proj'], stderr=subprocess.STDOUT)

It should give you the same Exception.

Try this one:

proj_ver_bytes = subprocess.check_output('/usr/local/bin/proj', stderr=subprocess.STDOUT)

I saw some forum post that were suggesting that the first argument in subprocess.check_output() should be a string for Raspberry Pi Python, instead of a list.

When you run pip, the first example is essentially what setup.py is doing in check_proj_version(). It is making sure that you have the correct version of PROJ installed.

EDIT added below:
One more test. From bash run the following:

$ /usr/local/bin/proj

$ echo $?

$? should print out the exit code.

Run this from a python console:

Return Exception:

It's interesting.
Because, run /usr/local/bin/proj is correctly return.

Try this one:

But, the above code seems to work normally.
Your thoughts are right.

One more test. From bash run the following:

Run echo $?:

0. No Error.

Check my proj permission:

I messed up the my first test. I should have testing it out before posting. Sorry. Ignore that one.

So, it sounds like the second test worked.

Does this work (Test 4)? (This is actually what is being run in setup.py by pip).

proj_ver_bytes = subprocess.check_output(['/usr/local/bin/proj'], stderr=subprocess.STDOUT)

If that reproduces the problem, this should be an easy fix.

@bluems can you try:

pip install git+https://github.com/snowman2/pyproj@657cc427

Looks like merging the change to master closed this issue. @bluems wr would still appreciate your feedback. Thanks!
