在 Ubuntu 15.10 上安装 Perl6 和 Panda。 bootstrap.pl 的问题

Question

我正在尝试在 Ubuntu 15.10 上安装 Panda。首先我尝试了：

git clone --recursive git://github.com/tadzik/panda.git
cd panda
perl6 bootstrap.pl

最后一条命令给出错误信息：

===SORRY!=== Error while compiling bootstrap.pl
Confused
at bootstrap.pl:3
------> use v6.⏏c;
    expecting any of:
        statement list

根据 @gfldex 的评论（见下文），我运行:

> perl6 --version
This is perl6 version 2014.07 built on parrot 6.6.0 revision 0

所以问题似乎是 Ubuntu 15.10 附带的旧版本的 Perl6。（我使用 sudo apt-get install rakudo 在 Ubuntu 上安装了 Perl6。）

我现在尝试将我的 Perl6 更新到最新版本：

wget http://rakudo.org/downloads/star/rakudo-star-2016.01.tar.gz
tar xzf rakudo-star-2016.01.tar.gz
cd rakudo-star-2016.01
perl Configure.pl --backend=moar --gen-moar
make
make install

但是最后一个命令失败了：

cd modules/panda && /home/hakon/install_rakudo/rakudo-star-2016.01/install/bin/perl6-m bootstrap.pl

在 @gfldex 的后续输入后，我尝试删除包 rakudo。也许二进制 /usr/bin/perl6 的存在会给安装程序造成混淆：

> sudo apt-get remove rakudo

Use 'apt-get autoremove' to remove them.

然后测试包是否被成功删除：

> pwd
/home/hakon/install_rakudo/rakudo-star-2016.01
> which perl6
./perl6
> perl6 --version
This is Rakudo version 2016.01.1 built on MoarVM version 2016.01
implementing Perl 6.c.
> cd ..
> perl6 --version
The program 'perl6' is currently not installed. You can install it by typing:
sudo apt-get install rakudo
> cd rakudo-star-2016.01

然后我重试了 make install，但它失败了，并显示了与之前完全相同的错误消息。

然后我尝试了完全重新安装：

cd ..
rm -rf rakudo-star-2016.01/
wget http://rakudo.org/downloads/star/rakudo-star-2016.01.tar.gz
tar xzf rakudo-star-2016.01.tar.gz
cd rakudo-star-2016.01
perl Configure.pl --backend=moar --gen-moar
make
make install

但我仍然从 make install 收到相同的错误消息。

然后我再次尝试手动重新安装 Panda

cd ..
git clone --recursive git://github.com/tadzik/panda.git
cd panda
../rakudo-star-2016.01/perl6 bootstrap.pl

但这也失败并显示相同的错误消息 (Perl v6.0.0 required--this is only v5.20.2)。

Answer 1

根据 irc.freenode.net 上 IRC 频道 #perl6 上的用户 RabidGravy：

the problem with installing panda there is due to PERL5LIB or PERLLIB being set in the environment

所以现在我尝试在安装前清除 PERL5LIB：

PERL5LIB= make install

而且效果很好。

最后，我必须将以下路径添加到 ~/.bashrc 以完成设置：

/home/hakon/install_rakudo/rakudo-star-2016.01/install/bin
/home/hakon/install_rakudo/rakudo-star-2016.01/install/share/perl6/site/bin

（很高兴知道为什么必须清除 PERL5LIB，很难。）
