pycharm安装各种包的错误解决历程

---

镜像

首先，安装每个包的命令后面都加上了镜像-i https://pypi.douban.com/simple，是因为之前没加镜像都装不上，加了之后报错明显减少很多，可以参考这篇文章python pip install指定国内源镜像

安装jupyter包

起初，在命令提示符（cmd）中安装jupyter包，使用的是pip install --user jupyter -i https://pypi.douban.com/simple”命令，结果安装中途报错，如下图。（其中我需要加–user，主要是因为脑热把python装在C盘了，所以需要系统权限）


注意到第二个图中，最后几行：

 distutils.errors.DistutilsError: Command '['c:\\users\\asus\\appdata\\local\\programs\\python\\python39\\python.exe', '-m', 'pip', '--disable-pip-version-check', 'wheel', '--no-deps', '-w', 'C:\\Users\\asus\\AppData\\Local\\Temp\\tmpi2fi2veo', '--quiet', 'Cython']' returned non-zero exit status 2.
    ----------------------------------------
ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.

其中讲到了“-m”等，并且受到博客python xxx.py和python -m xxx.py有什么区别！的启发（路径和启动），加上了python -m，如下：

python -m pip install --user jupyter -i https://pypi.douban.com/simple

结果：

安装成功了！
其中，提示由于少了wheel包，所以安装部分包使用的是py旧版本安装，所以后面再装上wheel包即可，防止在出现这种警告。

安装lmdb包

同上，使用命令python -m pip install --user lmdb -i https://pypi.douban.com/simple

    During handling of the above exception, another exception occurred:

    ----------------------------------------
ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.

错误提示少了“patch_ng”文件，查了痕迹也没找到解决方案，在网上也没找到过“patch_ng”源文件，但后来突然想，直接也用上面命令安装这个文件行不行（虽然它不是包），结果成功了！
不过换了一个错误：

 building 'cpython' extension
    error: Microsoft Visual C++ 14.0 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft.com/downloads/
    ----------------------------------------

主要是缺少Microsoft Visual C++ 14.0，可以从这里提取包Microsoft Visual C++ 14.0(安装包)
然后出现了以下错误：

 LINK : fatal error LNK1158: cannot run 'rc.exe'
    error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\\link.exe' failed with exit code 1158

错误是少“LINK : fatal error LNK1158: cannot run ‘rc.exe’”，所以参照一下博客：出现LINK : fatal error LNK1158: cannot run ‘rc.exe’ 错误的解决办法
成功解决问题！

安装mahotas包

出现错误：

numpy1.19.3；platform_system"Windows"
numpy1.19.4；platform_system"linux"
windows只能安装1.19.3，直接使用pip3 install命令安装的是最新的1.19.4版本，因此在安装时需要指定版本：
先卸载原版本：

pip uninstall numpy

然后安装1.19.3版本：

python -m pip install --user numpy==1.19.3 -i https://pypi.douban.com/simple

这样，继续安装mahotas即可成功
