javascript -/tmp/chromium : error while loading shared libraries: libnss3. 所以:无法打开共享对象文件:没有这样的文件或目录 Vercel

Question

当我尝试访问上传到 vercel 服务器上的 API 时，我收到了这个错误。
有没有人有同样的错误？
当我在本地运行它时，它工作正常。

我遇到了同样的问题，即 puppeteer 在我的本地环境中运行良好，但是当我部署到 AWS EC2 时，我遇到了同样的错误 共享加载库
解决方案

首先检查你正在运行的nodejs的版本，如果不是低于 v14.0 或高于 v14.0 .升级或降级(建议升级)并重新启动您的应用程序然后尝试。

The most common cause is a bug in Node.js v14.0.0 which broke extract-zip, the module Puppeteer uses to extract browser downloads into the right place. The bug was fixed in Node.js v14.1.0, so please make sure you're running that version or higher. Alternatively, if you cannot upgrade, you could downgrade to Node.js v12, but we recommend upgrading when possible.

琐碎:-确保您的项目文件夹所在的目录不属于root。

在windows环境下运行时可能遇到此问题的 friend 可以尝试通过 ignoreDefaultArgs: ['--disable-extensions'] 从代码启动 Chrome 时的选项，即

const browser = await puppeteer.launch({ignoreDefaultArgs: ['--disable-extensions']})

这将停用 puppeteer 的默认行为，以禁用 chromium/chrome 通常使用的任何扩展。
Linux 和 MACOS 使用
导致此错误的问题

UnhandledPromiseRejectionWarning: Error: Failed to launch the browser process! error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory TROUBLESHOOTING

大部分但并非所有时间都是由于缺少最新版本中所需的依赖项造成的。好消息是您可以轻松检查导致崩溃的缺失 chrome 依赖项。

确保您位于项目的根文件夹中

导航到 node_modules 文件夹

导航到安装 puppeteer chrome Linux 工具的文件夹

• cd /project_folder/node_modules/puppeteer/.local-chromium/linux-some number/chrome-linux
  replace the linux-some number with whatever ls will output
• ls at /.local-chromium to check name of your directory

在最后一个目录 [ chrome-linux ] 运行以下命令以检查缺少的依赖项
ldd Chrome |不是

如果您看到任何缺少的依赖项，请运行此命令以安装所有内容并重新启动您的应用程序。

sudo apt-get install ca-certificates fonts-liberation libappindicator3-1 libasound2 libatk-bridge2.0-0 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgbm1 libgcc1 libglib2.0-0 libgtk-3-0 libnspr4 libnss3 libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 lsb-release wget xdg-utils

瞧!!一切都应该修复
