Question

我已按照以下命令（https://github.com/parse-community/parse-server）在本地安装解析服务器。

$ npm install -g parse-server mongodb-runner
$ mongodb-runner start
$ parse-server --appId myserver --masterKey myserver --databaseURI mongodb://localhost/test

将服务器文件下载并存储在~/.npm-global/lib/node_modules/parse-server。当我尝试运行第3个命令终端上的parse-server --appId myserver --masterKey myserver --databaseURI mongodb://localhost/test，我收到以下错误

parse-server: command not found

当我尝试从同一个文件夹在终端上运行npm start时，我收到以下错误

parse-server@2.7.4 start /home/user/.npm-global/lib/node_modules/parse-server
> node ./bin/parse-server

/home/user/.npm-global/lib/node_modules/parse-server/lib/ParseServer.js:124

我该怎么办呢？另一件事，我已经安装了mongodb并在尝试在我的笔记本电脑上安装parse-server之前使用它。

npm install -g parse-server mongodb-runner
mongodb-runner start

在我的笔记本电脑上安装另一个mongo db？

我可以使用以下命令将//Fetch the title of the active tab console.log("-----------Button Clicked------------"); var activeTab = browser.tabs.query({active: true, currentWindow: true}); console.log("---------Printing type of variable \"activeTab\""); if (typeof activeTab == "undefined") console.log("The object is undefined") else console.log("The type of activeTab is:" + typeof activeTab) console.log("The title of activeTab is:") console.log(activeTab.title);版本从nodejs更新为4.2.6来解决问题

8.11.1

之后，我添加了curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash - sudo apt-get install -y nodejs文件

的解析服务器路径

/etc/enviroment

附加了这一行sudo gedit /etc/enviroment 然后我运行:~/.npm-global/bin命令并能够从终端启动parse-server

source /etc/enviroment

parse-server无法启动
