The following sections provide troubleshooting suggestions.以下部分提供了故障排除建议。

View npm Log Files查看npm日志文件

The npm log files are a good place to start if you encounter a problem. 如果遇到问题，npm日志文件是一个很好的起点。The log file location will vary depending on your npm installation. 日志文件的位置将根据您的npm安装而有所不同。It will be something like:它将类似于：

/<NPM USER HOME>/.npm/_logs/2021-09-16T22_03_34_534Z-debug.log

When you locate the log files, check the most recent one.找到日志文件后，请检查最新的日志文件。

Non-specific Error Message非特定错误消息

Problem: mongosh returns a non-specific error message when you try to start the shell.：mongosh在您尝试启动shell时返回一条非特定的错误消息。

Solution: Disable snippets, restart mongosh to continue debugging.：禁用snippets，重新启动mongosh以继续调试。

mongosh --nodb --eval 'config.set("snippetIndexSourceURLs", "")'

Error: Cannot find module

Problem: mongosh returns an error message like this when you try to start the shell:：mongosh在尝试启动shell时返回如下错误消息：

Error: Cannot find module '/<PATH to USER HOME>/.mongodb/mongosh/snippets/node_modules/@<REGISTRY NAME>/bad-snippet-name'

The npm log file may have lines like these:npm日志文件可能有如下行：

36 error code ELSPROBLEMS
37 error missing: @<REGISTRY NAME>/bad-snippet-name@*, required by snippets@

Solution: Edit the ~/.mongodb/mongosh/snippets/package.json file to remove the line with the bad-snippet-name.：编辑~/.mongodb/mongosh/snippets/package.json文件以删除具有bad-snippet-name的行。

In this example, do not forget to delete the trailing comma from the line above as well.在本例中，也不要忘记删除上面一行的尾部逗号。

{
   "dependencies": {
      "@mongosh/snippet-analyze-schema": "^1.0.5",
      "@mongosh/snippet-spawn-mongod": "^1.0.1",
      "npm": "*",
      "@<REGISTRY NAME>/bad-snippet-name": "^1.0.7"
   }
}

Problem: Uninstall fails, but the error message refers to a different snippet.：卸载失败，但错误消息引用了不同的代码段。

The following error message below is reformatted for readability:为了便于阅读，下面的错误消息已重新格式化：
