我已经使用Pip3成功安装了Ipython 6.0.0：
pip3 install IPython
但是尝试运行命令
Ipython
我收到此错误：
bash: IPython: command not found
这是pip list的结果：
这是pip3 show IPython

这是区分大小写的问题...
正确的字体是IPython。
pip 不区分大小写，请参见Is PyPI case sensitive?
IPython已安装为ipython（小写），如您的
class ViewController: UIViewController {
@IBOutlet weak var reportTableView: UITableView!
let reportGroup = ["Dietary", "Weight", "Sleep", "Meditation", "Fitness"]
let report = [["Calorie Breakdown", "Net Calories"], ["Last 3 Months"], ["Last 3 Months"],["Last 3 Months"],["Exercises by Type"]]
func numberOfSections(in tableView: UITableView) -> Int {
return report.count
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return reportGroup[section]
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "reportSegue" {
if let reportVC = segue.destination as? Report1ViewController, let indexPath = reportTableView.indexPathForSelectedRow {
reportVC.dataToDisplay = report[indexPath.section][indexPath.row]
}
}
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
}
extension ViewController: UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return report[section].count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
cell.textLabel?.text = report[indexPath.section][indexPath.row]
return cell
}
}
extension ViewController: UITableViewDelegate {
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
performSegue(withIdentifier: "report1Segue", sender: nil)
}
}
bash 区分大小写...
因此，只需输入pip3 show IPython。
正如您指定的ipython一样，我还建议调用pip3以避免python2 / 3的混乱。
