即使在代码和共享Web主机上的$ PATH中指定，无头Selenium驱动程序也无法找到Firefox二进制文件

Question

目标

我想让Selenium在我的Dreamhost共享网络主机上的虚拟python环境中运行Firefox无头。

问题

selenium驱动程序无法找到我的Firefox二进制文件，即使我已经在我的代码中指定了它的路径并将其添加到我的PATH中。

信息

我将64位firefox 46.0.1 tar解压缩到〜/ bin / firefox。 我也跑了chmod 777 ~/bin/firefox/firefox。 我没有sudo访问权限。

[SharedWebServer]$ cat ~/.bashrc
    export PATH="$PATH:~/bin/firefox"
    alias firefox="~/bin/firefox/firefox"
    alias pythonactivate='source $HOME/<DOMAIN>/env/bin/activate'
[SharedWebServer]$ hash
    hits    command
    0       /home/<user>/bin/firefox/firefox
[SharedWebServer]$ which firefox
[SharedWebServer]$
[SharedWebServer]$ export DISPLAY=:10
[SharedWebServer]$ export
    declare -x DISPLAY=":10"
    declare -x GEM_HOME="/home/<user>/.gems"
    declare -x GEM_PATH="/home/<user>/.gems:/usr/lib/ruby/gems/1.8"
    declare -x HOME="/home/<user>"
    declare -x LC_COLLATE="C"
    declare -x LOGNAME="<user>"
    declare -x MAIL="/home/<user>/Maildir/"
    declare -x OLDPWD
    declare -x PATH="/home/<user>/.gems/bin:/usr/lib/ruby/gems/1.8/bin/:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games"
    declare -x PS1="[\\h]\$ "
    declare -x PWD="/home/<user>"
    declare -x SHELL="/bin/bash"
    declare -x SHLVL="1"
    declare -x SSH_CLIENT="<blah>"
    declare -x SSH_CONNECTION="<blah>"
    declare -x SSH_TTY="/dev/pts/1"
    declare -x TERM="xterm"
    declare -x USER="<user>"

代码

firefox_binary = FirefoxBinary(firefox_path='/home/<user>/bin/firefox/firefox')
firefox_profile = custom_firefox_profile(images=False, css=True, flash=False)
driver=webdriver.Firefox(firefox_binary=firefox_binary,firefox_profile=firefox_profile)
vdisplay = Xvfb()
vdisplay.start()

错误

＆＃34;请指定firefox二进制位置或安装firefox＆＃34;）

RuntimeError：无法在系统路径中找到firefox。请指定firefox二进制位置或安装firefox

实际错误块：

[SharedWebServer]$ source $HOME/<DOMAIN>/env/bin/activate
(env)[SharedWebServer]$ python main.py
