`zsh: no such file or directory .../undetected-chromedriver`

I encountered this confusing error and wanted to note the cause and solution here.

Executing the code gave:

Traceback (most recent call last):

FileNotFoundError: [Errno 2] No such file or directory: '/home/thanh/.local/share/undetected_chromedriver/undetected_chromedriver'

Try executing the binary gave:

zsh: no such file or directory: /home/thanh/.local/share/undetected_chromedriver/undetected_chromedriver

I was using zsh on NixOS and encountered this after pip install undetected-chromedriver. The problem was with the way NixOS handle paths, which makes some required C libraries missing:

ldd /home/thanh/.local/share/undetected_chromedriver/undetected_chromedriver

Manually adding the missing libraries and making them visible should help.

One horrible way to work around this is to use nix-alien to create a new shell with every libraries included:

nix-alien \
    -l libdl.so.2 \
    -l libpthread.so.0 \
    -l libglib-2.0.so.0 \
    -l libnss3.so \
    -l libnssutil3.so \
    -l libnspr4.so \
    -l libm.so.6 \
    -l libxcb.so.1 \
    -l libgcc_s.so.1 \
    -l libc.so.6 \
    -l ld-linux-x86-64.so.2 \
    -l libpcre2-8.so.0 \
    -l libplds4.so \
    -l libplc4.so \
    -l librt.so.1 \
    -l libXau.so.6 \
    -l libXdmcp.so.6 \
    /nix/store/91jlw0ppx0zbzwz01q6wdjqyakrz6kmf-system-path/bin/bash \
;

Replace .../bin/bash with your shell, and then activate virtual environment, and then start working as usual.

In case you don't need/can't afford "hard automation" (auto login/captcha bypassing) and therefore don't truly need undetected-chromedriver, you can try opening Chrome's WebDriver port like google-chrome-stable --remote-debugging-port=9222, do the login/captcha entering, and then attach your "normal" Selenium code to do your automation:

options = webdriver.ChromeOptions()
options.add_experimental_option("debuggerAddress", "127.0.0.1:9222")
driver = webdriver.Chrome(options=options)
