Nodejs npm scripts fail with "SyntaxError: Unexpected token {"
Nodejs npm scripts fail with "SyntaxError: Unexpected token {"
我刚刚将我的 Reactjs 项目导入到 Ubuntu 上的一台新机器上,并使用 npm install
安装了大多数依赖项,但成功地禁止了以下内容:
npm WARN optional Skipping failed optional dependency /react-scripts/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: fsevents@1.0.17
npm WARN optional Skipping failed optional dependency /chokidar/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: fsevents@1.1.2
尝试 运行 带有 npm start
的项目失败:

尝试 运行 包括 npm run build

脚本全部失败,并出现完全相同的错误,在 SyntaxError 中引用每个文件中的相同行:

运行我原来机器上的相同脚本,一个Mac,成功。
我已尝试重新安装 node
/npm
,但未能解决问题。所谓的可选依赖项是否导致此失败?
感谢任何帮助。
您使用的 node.js v4 默认情况下不支持它失败的解构语法(const {field1, field2, ....} = object
)。
您有两个选择:
- 安装更新版本的 Node.js
- 运行 节点与将在版本 4.x.
中启用此功能的和谐标志
