运行 npm build 时找不到 Parcel 命令

Question

我正在尝试为 openlayers 创建一个捆绑包。我已按照教程https://openlayers.org/en/latest/doc/tutorials/bundle.html进行操作，当我到达时，npm run build出现以下错误。

\n\n

openmap@1.0.0 build /accounts/linuxuser/web_projects/openmap\nparcel build --public-url . index.html\nsh: parcel: command not found\n

\n\n

当我进入lsnode_modules文件夹时，我得到了。parcel -> ../parcel-bundler/bin/cli.js。\n当我cd进入node_modules文件夹时，找不到parcel-bundler文件夹。当我跑步时，npm install --save-dev parcel-bundler 我得到以下信息。

\n\n

  deasync@0.1.15 install /accounts/linuxuser/web_projects/openmap/node_modules/deasync\n  node ./build.js\n  sh: node: command not found\n  openmap@1.0.0 /accounts/linuxuser/web_projects/openmap\n

\n\n

我确实有 npm 安装。

\n\n

npm --version\n3.5.2\n

\n\n

运行后出错npm install --save-dev parcel-bundler

\n\n

文件夹结构是

\n\n

   openmap/\n       index.html\n       index.js\n       package.json\n       node_modules/\n

就我而言，我错误地运行了它，应该使用以下命令之一运行它：

npx parcel ...
yarn parcel ...
