配置Mocha以持续运行测试失败

Question

我试图配置mocha来运行测试，而不是使用命令手动运行：

node_modules\.bin\mocha -w

我得到的错误如下。

D:\Downloads\Bluemix\dw0015a\dw0015a\node_modules\mocha\lib\utils.js:626
    throw new Error("cannot resolve path (or pattern) '" + path + "'");
    ^

Error: cannot resolve path (or pattern) '-w'

我能够得到一种类似于您报告的行为，即在w选项前面加上一个"en dash“字符(Unicode U+2013)，而不是一个负字符。如下所示：

$ mocha –w
/home/x/local/lib/node_modules/mocha/lib/utils.js:626
        throw new Error("cannot resolve path (or pattern) '" + path + "'");
        ^

Error: cannot resolve path (or pattern) '–w'
    at Object.lookupFiles (/home/x/local/lib/node_modules/mocha/lib/utils.js:626:15)
[... etc ...]

确保使用减号(十六进制值0x2d)。
