How can I resolve the 'env: can’t execute 'node ' error in my custom n8n Docker image?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I am building a custom Docker image using the Dockerfile from the n8n GitHub master branch (https://github.com/n8n-io/n8n/blob/master/docker/images/n8n-custom/Dockerfile). When running the image either via docker-compose or with a single docker run command, I encounter the following error:

BASH
2025-02-14 16:15:49 env: can’t execute 'node  ': No such file or directory

I have done some debugging inside the container:

BASH
ldd $(which node)
        linux-vdso.so.1 (0x00007ffce09e2000)
        libstdc++.so.6 => not found
        libgcc_s.so.1 => /nix/store/19avl2s0rd4whz3b0n118qdrv6yr3b0g-xgcc-13.2.0-libgcc/lib/libgcc_s.so.1 (0x00007f5508a95000)
        libc.musl-x86_64.so.1 => not found
        libc.so.6 => /nix/store/87848rvrg5c7jmplpi0iapvbxyj9kfid-glibc-2.39-52/lib/libc.so.6 (0x00007f5503413000)
        /lib/ld-musl-x86_64.so.1 => /nix/store/87848rvrg5c7jmplpi0iapvbxyj9kfid-glibc-2.39-52/lib64/ld-linux-x86-64.so.2 (0x00007f5508abc000)

BASH
which node
/usr/local/bin/node

BASH
ls -l /usr/local/lib/node_modules/n8n/bin
total 8
-rwxr-xr-x 1 root root 2633 Feb 14 12:59 n8n
-rwxr-xr-x 1 root root   34 Feb 14 12:59 n8n.cmd

BASH
ln -s /usr/local/lib/node_modules/n8n/bin/node /usr/local/bin/node
ln: failed to create symbolic link '/usr/local/bin/node': File exists

From my investigation, it appears there may be two underlying issues:

Missing shared libraries for the node binary (e.g. libstdc++.so.6 and libc.musl-x86_64.so.1), suggesting a mismatch between the expected and available C libraries in the container.
A potential issue with an existing symlink or a malformed shebang (possibly containing extra spaces), which results in env trying to execute a wrongly named binary (like "node ").

I am using n8n version 1.79.0 on Windows 11 with Docker and SQLite. Here are the steps I used to build and run the container:

BASH
docker build -t n8n-custom -f docker/images/n8n-custom/Dockerfile .
docker volume create n8n_data
docker run -it --rm --name n8n -p 5678:5678 -v n8n_data:/home/node/.n8n n8n-custom

How can I adjust the Docker image to properly locate and execute the node binary and resolve this error?

The error

env: can’t execute 'node
': No such file or directory

indicates that while a node binary exists (as shown by which node returning /usr/local/bin/node), it isn’t executing properly. In your case the investigation reveals two issues:

Missing Shared Libraries:
Running ldd on the node binary shows missing libraries (for example, libstdc++.so.6 and libc.musl-x86_64.so.1). This suggests that the node binary (or one of its dependencies) is built against a different C library version or expects libraries that aren’t available in your Alpine‑based container. Without these libraries the binary cannot be executed.
Existing Symlink and Potential Shebang Issue:
You attempted to create a symlink from /usr/local/lib/node_modules/n8n/bin/node to /usr/local/bin/node but it failed because the file already exists. Also, the error message (with an apparent extra whitespace after "node") hints that the shebang line of one of the scripts might be malformed or include unexpected whitespace. In many cases, such an issue causes env to look for an executable literally named "node " (with trailing space), which naturally is not found.

Suggestions to Resolve the Issue

Ensure Compatibility of the Node Binary:
If the custom Dockerfile is based on alpine (using, for example, node:16‑alpine), verify that the node binary in use matches the expected C library (musl vs. glibc). You may:
- Either add the missing dependencies to the image (for instance, installing libstdc++ via apk may help)
- Or base your image on a Debian‑based Node image (like node:16) so that the node binary and its dependencies are aligned.
Check and Clean Up the Symlink/Shebang:
Since the symlink already exists and the error shows extra whitespace, inspect the script (for example, /usr/local/lib/node_modules/n8n/bin/n8n) for its shebang line. Ensure it uses a clean line such as:
#!/usr/bin/env node
with no trailing spaces or hidden characters.
Rebuild and Test Your Image:
Once you adjust the base image or install the missing libraries and make sure the shebang lines are correct, rebuild your custom image and test again with your standard commands:
```
BASH
docker build -t n8n-custom -f docker/images/n8n-custom/Dockerfile .
docker volume create n8n_data
docker run -it --rm --name n8n -p 5678:5678 -v n8n_data:/home/node/.n8n n8n-custom
```

By addressing the missing shared libraries (or choosing a compatible base image) and ensuring the node command is referenced correctly, you should be able to resolve the startup error.
