运行 npm build 时找不到 Parcel 命令

Question

我正在尝试为 openlayers 创建一个包。 我遵循了教程https://openlayers.org/en/latest/doc/tutorials/bundle.html当我进入npm run build我收到以下错误。

openmap@1.0.0 build /accounts/linuxuser/web_projects/openmap
parcel build --public-url . index.html
sh: parcel: command not found

当我ls的node_modules文件夹中，我得到。 parcel -> ../parcel-bundler/bin/cli.js 。 当我cd到 node_modules 文件夹时，找不到parcel-bundler 文件夹。 当我运行npm install --save-dev parcel-bundler我得到以下信息。

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

我确实安装了 npm。

npm --version
3.5.2

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

 WARN engine parcel-bundler@1.12.3: wanted: {"node":">= 6.0.0"} (current: {"node":"4.2.6","npm":"3.5.2"})

 deasync@0.1.15 install /accounts/linuxuser/web_projects/openmap/node_modules/deasync
 node ./build.js

 sh: node: command not found
 openmap@1.0.0 /accounts/linuxuser/web_projects/openmap
 └── ol@5.3.3  extraneous

文件夹结构是

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

在我的情况下，我错误地运行它，应该使用以下任一命令运行它：

npx parcel ...
yarn parcel ...
