【问题描述】：
tl;博士：
sqlite3 无法在 WSL Ubuntu 环境中编译其原生扩展，而在其他非 WSL Ubuntu 原生环境中它不会失败。
总结：
我在 Windows 10 Pro (19042.1288) 上安装了运行 Ubuntu 20.04.1 LTS 的 WSL2。我有一个安装了 Ruby 2.7.4 和 Ruby 3.0.2 的工作 rbenv 环境。在 gem 原生扩展编译时 (gem install sqlite3 -v '1.4.2' --source 'https://rubygems.org/') 它会吐出大量警告和错误，但第一个真正的错误是这个：
sqlite3.c:33:37: error: invalid type argument of ‘->’ (have ‘int’)
33 | # define RBIGNUM_LEN(x) RBIGNUM(x)->len
| ^~
我的尝试
包更新
我已经更新了我被告知相关的软件包：
$ sudo apt-get update
$ sudo apt-get install sqlite3 libsqlite3-dev libxslt-dev libxml2-dev
安装标志
我试过像这样使用--with-sqlite3-include 标志运行：
$ gem install sqlite3 -v '1.4.2' --source 'https://rubygems.org/' -- --with-sqlite3-include=/usr/include
从源码安装 sqlite3
这会导致从源代码（在 $PATH 中正确加载）有效安装 sqlite3，但不会更改 gem 本机扩展编译时的错误。
$ wget https://www.sqlite.org/2021/sqlite-autoconf-3360000.tar.gz
$ tar xvf sqlite-autoconf-3360000.tar.gz
$ cd sqlite-autoconf-3360000
$ ./configure
$ make
$ make install
在真正的 Ubuntu Machine™ 上进行操作
这很好用。这是让我相信这个问题与 WSL 相关的部分原因。 （创建一个新的 WSL Ubuntu 实例会产生同样的问题，所以我认为这不是我的环境）

【问题讨论】：
-
尝试较早版本的 gem？尝试从 Github 存储库的源代码构建？
-
@Casper 我很欣赏这个建议——gem 的早期版本（我试过版本
'1.3.13'）实际上会产生一个奇怪且不同的错误，libsqlite3 完全丢失了。添加到帖子。
