Question

我运行以下命令：

node_modules/.bin/jsdoc -r --destination /home/user/public_html/jsdoc-meta/ node_modules/jsdoc/

这就是我得到的。我在正则表达式中找不到错误：

/home/user/node_modules/jsdoc/lib/jsdoc/name.js:77
    var regexp = new RegExp('^' + memberof.toString() + REGEXP_SCOPE_PUNC);
                 ^
SyntaxError: Invalid regular expression: /^harmonyTestFixture.ES6 Template Strings.`\u{000042}\u0042\x42\u0\102\A`[~,#,.]/: Unterminated character class

节点（或者更确切地说是V8）尝试将其解析为UTF8转义序列：

/^harmonyTestFixture.ES6 Template Strings.`\u{000042}\u0042\x42\u0\102\A`[~,#,.]/
                                                                ^^^^^^

但是，由于\u0和102之间的反斜杠缺少字符，因此错误消息（Unterminated character class）。根据您要实现的目标，您可以删除该反斜杠：

/^harmonyTestFixture.ES6 Template Strings.`\u{000042}\u0042\x42\u0102\A`[~,#,.]/
                                                                  ^

或逃避反斜杠：

/^harmonyTestFixture.ES6 Template Strings.`\u\{000042\}\u0042\x42\u0\\102\A`[~,#,.]/
                                                                    ^^
