I am encountering an issue when running MultiQC on FastQC reports. The report is generated, but I receive the following error: Could not include file ‘assets/js/packages/[jszip.min.js](https://search.eitaa.com/?url=https://jszip.min.js)’: [Errno 2] No such file or directory: ‘/tmp/tmpXXXX/assets/js/packages/[jszip.min.js](https://search.eitaa.com/?url=https://jszip.min.js)’ MultiQC output: Report : multiqc\_[report.html](https://search.eitaa.com/?url=https://report.html) Data : multiqc\_data MultiQC complete Details: MultiQC version: v1.18 Installed using: sudo install (system-wide installation) OS: Ubuntu (Linux) Running inside: standard terminal (not conda/venv) The HTML report is created, but I am concerned that some assets may not be properly embedded. Questions ?Is this caused by an incomplete installation ?Is this related to system-wide installation with sudo ?Would reinstalling inside a virtual environment (venv or conda) resolve the issue Thank you for your help. ---

Hi @mahsa You’re making this easy for me with the questions at the end! 1. Yes 2. Possibly 3. Very likely There’s definitely something weird going on with your installation, I can think of no reason why you’d have asset files within your `/tmp` directory. And using `sudo` is generally a big no-no. While you’re at it, I’d recommend upgrading to the latest version, [version 1.18](https://github.com/MultiQC/MultiQC/releases/tag/v1.18) is 2.5 years old now. > **[Installation | Seqera Docs](https://docs.seqera.io/multiqc/getting_started/installation)** > > How to install MultiQC on your system Hope that helps! ---

Thank you very much for your clarification and for pointing out the installation issue. I really appreciate your help. I have one additional question. When I tried to install MultiQC using pip install multiqc, I received the following error: ```auto error: externally-managed-environment This environment is externally managed. ``` It suggests that the Python installation is managed by the system (Debian/Ubuntu) and recommends using `apt`, a virtual environment, or `--break-system-packages`. Could you please clarify why this happens when using pip? Is this related to PEP 668 restrictions in newer Ubuntu/Debian versions? ---

Hi @mahsa, There are many answers to this question. As you said, trying to install with your system Python is almost always problematic and you should definitely not do that. I would instead try to use any of the following options: - Docker / Singularity (if running within a pipeline) - [Astral’s uv](https://docs.astral.sh/uv/) (`uv tool install multiqc`) - Conda ([miniforge](https://conda-forge.org/download/)) - Python virtual environments In all cases, MultiQC won’t be trying to install into / use your system version of Python and you shouldn’t get these conflicts.
