Question

我试图构建sklearn.tree子包，其中包含一些Cython代码。我在Windows上使用python3.6.1和numpy1.12.1。在

文件setup.py（可以下载here）包含distutils配置，代码如下 config.add_extension("_tree", sources=["_tree.pyx"],...) 所以我希望sources（这个变量通过下面列出的一个长函数堆栈进行浮点运算）是一个字符串列表。在

但是，在尝试构建包时，我收到了下面列出的输出。这意味着build_src.py中函数中的source不是一个字符串而是一个列表。在

所以问题是：

1. 事实上，列表在哪里变成了一个字符串？在
2. 这个错误是由我构建模块的方式引起的吗？如果是，如何正确地构建它？在
3. 这个错误是由setup.py的写入方式引起的吗？如果是这样，如何改变？sklearn的开发者是如何使用它的？在
4. 这个错误是由我的环境造成的吗？如果是，我应该改变什么？在
