安装WWW::HtmlUnit时找不到类com.gargoylesoftware.htmlunit.WebClient

Question

我正在尝试在64位的Ubuntu12.04中安装WWW::HtmlUnit for perl。我在遵循CPAN page的指示。

然而，我收到了一个错误，说明

Class com.gargoylesoftware.htmlunit.WebClient not found at /usr/local/lib/perl/5.14.2/Inline/Java.pm line 619.

我已经在下面粘贴了我的整个日志输出。我还看到了其他一些对这个问题的回答，但都是针对Windows而不是Linux。

Answer 1

然而，把另一个答案留给后人，问题是作者借用了最新的版本。正如您在消息中看到的，他忘记了包括几个关键文件。

Warning: the following files are missing in your kit:
    lib/WWW/HtmlUnit/jar/commons-codec-1.4.jar
    lib/WWW/HtmlUnit/jar/commons-io-2.0.1.jar
    lib/WWW/HtmlUnit/jar/commons-lang-2.6.jar
    lib/WWW/HtmlUnit/jar/cssparser-0.9.5.jar
    lib/WWW/HtmlUnit/jar/htmlunit-2.9.jar
    lib/WWW/HtmlUnit/jar/htmlunit-core-js-2.9.jar
    lib/WWW/HtmlUnit/jar/httpclient-4.1.2.jar
    lib/WWW/HtmlUnit/jar/httpcore-4.1.2.jar
    lib/WWW/HtmlUnit/jar/httpmime-4.1.2.jar
    lib/WWW/HtmlUnit/jar/nekohtml-1.9.15.jar

这需要一个bug标签(实际上有两个，我在类路径代码中发现了一个bug )。

在此期间，您可以尝试安装旧版本：

cpanm http://cpan.metacpan.org/authors/id/A/AW/AWWAIID/WWW-HtmlUnit-0.16.tar.gz

(根据需要使用sudo和JAVA_HOME )。

Answer 2

你跟踪installation instructions了吗？看起来Inline::Java找不到你的java库了。

您可能需要检查是否将JAVA_HOME设置为正确的路径。我相信你可以通过运行下面这样的命令来获得它：

update-alternatives --query java | perl -ne 'print if s/Value: //'

对我来说，这给了我：

/usr/lib/jvm/java-6-sun/jre/bin/java

但是你不想要垃圾桶的部分所以我会用

JAVA_HOME=/usr/lib/jvm/java-6-sun

编辑:我也不想要/jre
