Question

我正在尝试升级到Babel到6.4。在解决了require的一系列问题之后，现在我对丢失分号有很多错误：

ERROR in ./src/components/views/HomePage/main.js
Module build failed: SyntaxError: /Users/chris/ss/components/views/HomePage/main.js: A semicolon is required after a class property (16:23)

     |                        ^

    at Parser.pp.parseTopLevel (/Users/chris/ss/node_modules/babel-core/node_modules/babylon/index.js:1823:8)

是否有一个linter或一些实用程序可以自动修复所有这些？

Answer 1

哇，人们真的为此付出了努力！ See this issue on the Babel Repo

看完这篇文章后，巴贝尔会改变这一点。

此外，this response to the same issue建议还原Babel版本，直到问题解决为止：

<强>的package.json

"babel": "<6.3.0",
"babel-cli": "<6.3.0",
"babel-core": "<6.3.0",
"babylon": "<6.3.0",

据我所知，尽管如此，仍然可以告诉我们已经提到的TC39规范。

您可以使用JSCS＆＃39; requireSemicolons规则自动修复此内容。

https://github.com/jscs-dev/node-jscs/pull/2057 - 在2.9.0版本中添加了此内容。
