我正在尝试在Alpine 3.10 docker容器中专门运行GeckoDriver v0.26.0 python:3.6.6-alpine3.10。
python:3.6.6-alpine3.10
在弄清楚一些事情之后,我碰壁了:
/ # geckodriver --version Error relocating /usr/bin/geckodriver: __register_atfork: symbol not found Error relocating /usr/bin/geckodriver: __res_init: symbol not found
我想念什么?
首先启动docker容器:
docker run -it python:3.6.9-alpine3.10 /bin/sh
然后尝试安装GeckoDriver
/ # wget https://github.com/mozilla/geckodriver/releases/download/v0.26.0/geckodriver-v0.26.0-linux64.tar.gz / # tar -zxf geckodriver-v0.26.0-linux64.tar.gz -C /usr/bin / # geckodriver --version /bin/sh: geckodriver: not found.
真?但我只是提取了它…嗯…好 提取正确吗?是对的$PATH吗
$PATH
/ # ls -lah /usr/bin/geckodriver -rwxr-xr-x 1 1000 1000 6.7M Oct 12 10:19 /usr/bin/geckodriver / # echo $PATH /usr/local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
是。好吧,让我们用谷歌搜索。好吧,也许我应该检查一下file信息。默认情况下,Alpine没有。
file
/ # apk add file fetch http://dl-cdn.alpinelinux.org/alpine/v3.10/main/x86_64/APKINDEX.tar.gz fetch http://dl-cdn.alpinelinux.org/alpine/v3.10/community/x86_64/APKINDEX.tar.gz (1/2) Installing libmagic (5.37-r1) (2/2) Installing file (5.37-r1) Executing busybox-1.30.1-r2.trigger OK: 24 MiB in 36 packages / # file /usr/bin/geckodriver /usr/bin/geckodriver: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.26, BuildID[sha1]=32c4cfc2d9346336dc7c20e99a62df9be344d609, with debug_info, not stripped
对于同一问题的答案说要检查/lib64/ld- linux-x86-64.so.2:
/lib64/ld- linux-x86-64.so.2
/ # ls /lib64 ls: /lib64: No such file or directory
失踪。好的,我们如何得到呢?在pkgs.alpinelinux说,它的一部分libc6-compat。酷安装,一切都会起作用…对吗?
libc6-compat
/ # apk add libc6-compat (1/1) Installing libc6-compat (1.1.22-r3) OK: 24 MiB in 37 packages / # ls /lib64 ld-linux-x86-64.so.2 / # geckodriver --version Error loading shared library libgcc_s.so.1: No such file or directory (needed by /usr/bin/geckodriver) Error loading shared library ld-linux-x86-64.so.2: No such file or directory (needed by /usr/bin/geckodriver) Error relocating /usr/bin/geckodriver: __register_atfork: symbol not found Error relocating /usr/bin/geckodriver: _Unwind_Resume: symbol not found Error relocating /usr/bin/geckodriver: __res_init: symbol not found Error relocating /usr/bin/geckodriver: _Unwind_GetIP: symbol not found Error relocating /usr/bin/geckodriver: _Unwind_Backtrace: symbol not found
…好吧,至少现在它可以将其识别为可执行文件…好,所以我们需要libgcc_s.so.1。在libgcc中。说得通。
libgcc_s.so.1
/ # apk add libgcc (1/1) Installing libgcc (8.3.0-r0) OK: 24 MiB in 38 packages / # geckodriver --version Error loading shared library ld-linux-x86-64.so.2: No such file or directory (needed by /usr/bin/geckodriver) Error relocating /usr/bin/geckodriver: __register_atfork: symbol not found Error relocating /usr/bin/geckodriver: __res_init: symbol not found
什么?我们ld-linux-x86-64.so.2进去了/lib64,在哪里看?我确实注意到该gcompat包装为/lib/ld-linux-x86-64.so.2,也许它在那儿?
ld-linux-x86-64.so.2
/lib64
gcompat
/lib/ld-linux-x86-64.so.2
# / apk add gcompat (1/2) Installing libucontext (0.1.3-r1) (2/2) Installing gcompat (0.4.0-r0) OK: 24 MiB in 40 packages # / geckodriver --version Error relocating /usr/bin/geckodriver: __register_atfork: symbol not found Error relocating /usr/bin/geckodriver: __res_init: symbol not found
那就是我的位置。搜寻__register_atfork并__res_init不会返回任何有用的信息。
__register_atfork
__res_init
因此,此问题的根本原因似乎是Alpine使用musl libc和GeckoDriver(间接)使用glibc。
SGerrand 为Alpine Linux提供了一个很棒的glibc兼容性层软件包,我们将利用它。
