Question

我在拿我的手法时,就谈了一个问题。

I installed Python 2.7 on Windows 7, bit 64. I got an error "No module named serial" when I compiled my code:

import serial

ser = serial.Serial("COM5", 9600)

ser.write("Hello world")

x = ser.readline()

print(x)

I tried many ways to crack this problem, such as installed Canopy to setup virtual environment, make sure pip is there, no Python v 3.x installed. But still cannot get it out.

任何建议都会得到赞赏。

Answer 1

Serial is not included with-030. 这是你需要单独安装的一揽子方案。

Since you have pip installed you can install serial from the command line with:

pip install pyserial

或者,您可从。它希望你再次使用3号,这样就点击了3号安装机。

然后,你就能够进口你此前所尝试的序列。

Answer 2

第一次使用指挥

pip uninstall pyserial

Then run again

 pip install pyserial

上述指挥系统将配备系统口译员。

Answer 3

You must have the pyserial library installed. You do not need the serial library.Therefore, if the serial library is pre-installed, uninstall it. Install the pyserial libray. There are many methods of installing:-

pip install pyserial
Download zip from pyserial and save extracted library in Lib>>site-packages folder of Python.
Download wheel and install wheel using command: pip install <wheelname>

链接:

After installing Pyserial, Navigate to the location where pyserial is installed. You will see a "setup.py" file. Open Power Shell or CMD in the same directory and run command "python setup.py install". Now you can use all functionalities of pyserial library without any error.

Answer 4

在我的案件中,以下指挥官做了工作:

pip3 install pyserial

Answer 5

sudo apt install python-serial python3-serial

将其处理完毕,将其用于Esp32

sudo python setup.py install

Answer 7

I had this same problem multiple times but finally found solution.

我安装了多台沙里。同Raspberry Pi一样,有人安放了Adhur3.5,我还安装了3.9.2套,没有安装3.5套。然后,我安装了有镜头并尝试了我的节目。无模块但是,理由是,python3中的气球象征联系指Python3.9.2版本,但pip3则指python3.5。因此,在Python3.5安装了玩具,在Python3.9.2的操作中,无法理解。然后,我把第3页的象征意义改为右版和沃伊拉,所有东西都做不起!

Answer 8

Firstly uninstall pyserial using the command pip uninstall pyserial

Then go to https://www.lfd.uci.edu/~gohlke/pythonlibs/
download the suitable pyserial version and then go to the directory where the file is downloaded and open cmd there
then type pip install "filename"(without quotes)

Answer 9

对我表示高兴。 Some断了。提出的所有解决办法都是徒劳的。

sudo pip install serial Requirement already satisfied: serial in /usr/local/lib/python3.8/dist-packages (0.0.97)

sudo pip3 install serial Requirement already satisfied: serial in /usr/local/lib/python3.8/dist-packages (0.0.97)

Same for pyserial, it was already installed.

解决办法: 我替换了使用Python3而不是python2的象征联系。

Answer 10

通常情况下,与我的情况一样,手工安装新版本能够将宇宙的位置从最低程度改为升级版本。

例如,在安装Arduino IDE之前,我刚刚安装了3,10枚,这只是造成问题重重。

I uninstalled pyserial by trying pip uninstall and then

页: 1

sudo apt purge python3.10

之后,我安装了ip,然后又安装了erial,这是trick的。

当有人用 su子 ran倒时,我发现这种错误,用 su子重新安装了细菌,帮助我:
