/usr/local/bin/solc: Permission denied

[svidorozhd]

I tried to install solc-select as specified in the "Quickstart" description. When asked to overwrite /usr/local/bin/solc, the error, described in the title, occurs. Using -privileged flag in the Docker call does not solve this problem.

The same thing, macOS Mojave 10.14.3

I suspect the issue is one of the following:

1. You do not have Homebrew installed;
2. Homebrew is misconfigured; or
3. Your user does not have permission to write to /usr/local/bin.

If it's #1, then the easiest solution is to install Homebrew. To diagnose the other possibilities, what is the result of running ls -lad /usr/local/bin?

Alternatively, you can always install it to a different directory in your PATH by setting the PREFIX environment variable to the desired installation path before running the quickstart instructions.

I'm having the same issue, and for me the result is: drwxrwxr-x 239 paulcowgill admin 7648 May 22 16:04 /usr/local/bin

I have the same issue on 10.14.4.

Also tried removing solc brew uninstall solidity, this command docker run --read-only -i --rm --entrypoint='/bin/sh' trailofbits/solc-select:latest -c 'cat /usr/bin/install.sh' | bash -e runs with no output and yet -bash: solc: command not found

After pulling the image, I was having a lot of difficulty getting the docker run command working. It seemed to be failing silently. Removing the -e at the end of the command resulted in this error: bash: line 25: /usr/local/bin/solc: Permission denied.

So I tried installing in a different location:

export PREFIX=/usr/local
docker run --read-only -i --rm --entrypoint='/bin/sh' trailofbits/solc-select:latest -c 'cat /usr/bin/install.sh' | bash

This seemed to install solc successfully. But then, running the command solc --version resulted in -bash: /usr/local/bin/solc: Permission denied.

cd /usr/local/bin
chmod u+x solc

After that, solc seems to be working as expected. Hope this helps.

Similar issue here:

Overwrite /snap/bin/solc? [yN] y
bash: line 25: /snap/bin/solc: Permission denied

which I solved initially, but then I couldn't get to run solc:

$ solc --help

mount: mounting /bin on /workdir/bin failed: Permission denied
mount: mounting /dev on /workdir/dev failed: Permission denied
mount: mounting /proc on /workdir/proc failed: Permission denied
mount: mounting /sys on /workdir/sys failed: Permission denied

I tried installing solc-select on my Mac as per the README instructions but it silently failed

[~]$ docker pull trailofbits/solc-select
Using default tag: latest
latest: Pulling from trailofbits/solc-select

[~]$ solc --version
-bash: solc: command not found

Trying again without the -e gave the follow

docker run --read-only -i --rm --entrypoint='/bin/sh' trailofbits/solc-select:latest -c 'cat /usr/bin/install.sh' | bash
Overwrite /usr/local/bin/solc? [yN] y
bash: line 51: /usr/local/bin/solc: Permission denied
Installed solc to /usr/local/bin/solc

The same result if I ran it using sudo

My solc was previously installed using brew

[~]$ ls -l `which solc`
lrwxr-xr-x  1 nicholasaddison  wheel  34 14 Aug 08:29 /usr/local/bin/solc -> ../Cellar/solidity/0.5.11/bin/solc

After removing /usr/local/bin/solc, the script fails with as the default location is solc is not installed is /usr/bin/solc and not /usr/local/bin/solc

[~]$ docker run --read-only -i --rm --entrypoint='/bin/sh' trailofbits/solc-select:latest -c 'cat /usr/bin/install.sh' | bash
bash: line 51: /usr/bin/solc: Operation not permitted

I tried installing using to a different location using the PREFIX env variable, but that doesn't work either

[~]$ mkdir solc-select
[~]$ cd solc-select/
[solc-select]$ export PREFIX=~/solc-select
[solc-select]$ mkdir bin
[solc-select]$ touch bin/solc
[solc-select]$ docker run --read-only -i --rm --entrypoint='/bin/sh' trailofbits/solc-select:latest -c 'cat /usr/bin/install.sh' | bash

For those who encounter this later, I had the same problem. Either was getting permission denied, operation not permitted, or error relocating.

I took the following steps to get it to work:

export PREFIX=/Users/brockelmore/solc-select
docker pull trailofbits/solc-select
docker run --read-only -i --rm --entrypoint='/bin/sh' trailofbits/solc-select:latest -c 'cat /usr/bin/install.sh' | bash -e
sudo ln -s /Users/brockelmore/solc-select/bin/solc /usr/local/bin

Basically, all I am doing is building in a known permitted location via PREFIX then symlinking back to /usr/local/bin so that I can run the executable from everywhere and applications like slither can access the executable.

This shouldn't be a problem anymore as we changed solc-select to be a Python package https://github.com/crytic/solc-select/releases/tag/0.2.0.
