Question

我正在尝试以用户身份安装HTML :: TreeBuilder :: XPath。但是我得到了这个错误：

Building and testing HTML-Parser-3.71 ... FAIL
! Installing HTML::Entities failed. See /home/user/.cpanm/build.log for details.

因此，如果我查看此文件 /home/user/.cpanm/build.log ，我会收到此错误：

Result: FAIL
Failed 3/48 test programs. 0/423 subtests failed.
make: *** [test_dynamic] Error 255
-> FAIL Installing HTML::Entities failed. See /home/user/.cpanm/build.log for details.

-> FAIL Bailing out the installation for HTML-TreeBuilder-XPath-0.14. Retry with --prompt or --force.

所以我尝试手动安装 HTML :: Entities ，我收到此错误：

  Successfully installed HTML-Tagset-3.20
    Building and testing HTML-Parser-3.71 ... FAIL
    ! Installing HTML::Entities failed. See /home/user/.cpanm/build.log for details.
    1 distribution installed

Can't locate HTML/Tagset.pm in @INC (@INC contains: /home/user/.cpanm/work/1403630727.28688/HTML-Parser-3.71/blib/lib /home/user/.cpanm/work/1403630727.28688/HTML-Parser-3.71/blib/arch /etc/perl /usr/local/lib/perl/5.14.2 /usr/local/share/perl/5.14.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.14 /usr/share/perl/5.14 /usr/local/lib/site_perl .) at /home/user/.cpanm/work/1403630727.28688/HTML-Parser-3.71/blib/lib/HTML/TokeParser.pm line 10.

所以它说它找不到HTML :: Tagset，但它之前只安装了几行！最后，我得到了这个错误：

Result: FAIL
Failed 3/48 test programs. 0/423 subtests failed.
make: *** [test_dynamic] Error 255
-> FAIL Installing HTML::Entities failed. See /home/user/.cpanm/build.log for details.

如果我看看/home/user/.cpanm/build.log，我会得到完全相同的输出。

请问有什么不对？

Answer 1

鉴于你无法从命令行找到HTML :: Tagset模块，你可能没有实际安装它，尽管被告知你有。

另一项测试是：

    $ perldoc HTML::Tagset

然后我会使用locate(1)

寻找它

    $ locate HTML/Tagset.pm

你可能会得到很多你需要经历的输出，或者你可能得不到。您可能会被告知定位所依赖的数据库未初始化或已过期。您可以刷新数据库，也可以尝试find(1)

   $ find / -name 'Tagset.pm' -print  | less

如果您仍然无法找到它，或者您厌倦了搜索，那么只需启动您最喜爱的CPAN客户端，然后明确安装HTML::Tagset然后HTML::Entities。

Answer 2

我没有告诉cpanminus使用我的本地图书馆。

以下是以用户身份安装所有模块的解决方案：

cd ~/;
cpanm local::lib;
echo 'eval `perl -I$HOME/perl5/lib/perl5 -Mlocal::lib`' >> ~/.bashrc ;
source ~/.bashrc;

之后，我可以用

作为用户安装所有模块和依赖项

cpanm module::name

无法使用cpanm安装HTML :: TreeBuilder :: XPath
