我试图相对神秘地要求一个文件,发生了以下情况
这很好,它指向 /Users/marcos/Desktop/Taper/lib/utils.js
myPath = "/Users/marcos/Desktop/Taper/lib/./utils";
require(myPath);
这不是,但它应该指向完全相同的文件:
require.paths.unshift("/Users/marcos/Desktop/Taper/lib")
require("./utils"); //Doesn't work with './'
require("utils"); //Works Fine
任何人都知道为什么在这种情况下我仍然不能使用 ./
来加载路径,因为
require("path").resolve("/Users/marcos/Desktop/Taper/lib", "./utils")
kết quả:
"/Users/marcos/Desktop/Taper/lib/utils"
不管怎样?
Cảm ơn trước
更新:
từ tài liệu :
A module prefixed with '/'
is an absolute path to the file. For example, require('/home/marco/foo.js')
will load the file at /home/marco/foo.js
.
A module prefixed with './'
is relative to the file calling require()
. That is, circle.js
must be in the same directory as foo.js
vì require('./circle')
to find it.
Without a leading '/' or './' to indicate a file, the module is either a "core module" or is loaded from a node_modules
thư mục.
If the given path does not exist, require()
will throw an Error with its mã số
property set to 'MODULE_NOT_FOUND'
.
这是原始答案,指的是 require.paths
(不再支持):
từ tài liệu :
在 Node 中,require.paths
是一个字符串数组,表示要搜索模块的路径当它们没有以 '/'
为前缀时,'./'
,hoặc '../'
.
(强调我的)
